Intensive agricultural practices have stimulated progressive degradation of soil quality in the Mollisols of Northeast China,resulting in curtailed crop productivity.Although conservation tillage patterns have been modified to better suit Mollisols in recent years,whether conservation tillage can effectively enhance soil organic carbon(SOC)and crop yield remains controversial.In our study,the effects of two modified conservation tillage(MCT)patterns,the strip tillage with straw cover(STSC)and straw mixture amendment tillage(SMAT),on soil aggregate stability,SOC stock,enzyme activities,microbial communities,and crop yields were evaluated after five years of implementation.The results revealed that compared with conventional tillage(CT),both STSC and SMAT increased soil dissolved organic carbon(DOC),easily oxidized organic carbon(EOC),particulate organic carbon(POC),and mineral-bound organic carbon(MOC),thereby raising SOC content and reinforcing the stability of soil aggregates.The microbial taxa,Bacillus,Gemmatimonadaceae,Sphingomonas,Nocardioides,Blastococcus,Streptomyces,Trichoderma,Holtermanniella,Talaromyces,Didymella,and Fusicolla,were identified as potential contributors to carbon(C)sequestration.Soil microbial diversity and key taxa were positively correlated with SOC.Additionally,both STSC and SMAT raised the effective panicle number,kernels per ear,and 100-grain weight,as well as nitrogen and phosphorus absorption by maize grains and rhizomes,further increasing maize yield,with a more pronounced effect of SMAT than STSC.To sum up,the implementation of MCT can considerably strengthen C sequestration and crop productivity in the Mollisol region of Northeast China,contributing to farmland ecological protection and improved agroecological efficiency. 展开更多

Phytolacca americana is a known rare earth element(REE)hyperaccumulator,notable for its high biomass and rapid growth rate.However,its capacity to tolerate and accumulate REEs under high-exposure conditions is relatively limited,which restricts its utilization in agromining on soils heavily contaminated with REEs.Silicon(Si)has been shown to effectively mitigate metal(loid)s stress in various plants,and to promote REE tolerance in the well-known hyperaccumulator fern Dicranopteris linearis.This study aimed to assess the effects of Si on REE agromining using P.americana and to elucidate the underlying mechanisms.The results show that foliar Si application significantly increases the REEs accumulation of P.americana by as much as 73.6%and 172.4%in hydroponic and pot experiments respectively.Notably,Si application enhances the retention of REEs within the cell walls,primarily through the formation of silicate particles and/or modifications of the cell walls.Transcriptome analysis indicates that foliar Si application initially mitigates the toxicity of REEs by inducing an upregulation of genes associated with stress response and antioxidant enzymes,which facilitates the rapid elimination of accumulated reactive oxygen species.With increasing Si application,the abnormal overexpression of stress response genes,as well as genes involved in flavonoid biosynthesis and cell division,is alleviated,further implying that the entry of REE into the cytoplasm can be effectively hindered.This study shows that foliar Si application represents a potentially cost-efficiency agronomic practice for improvement of REE agromining using P.americana. 展开更多

This study aimed to elucidate the effects of varying seedling ages at planting on the agronomic traits and nutrient content of stem lettuce.The early-maturing variety“WS120”and the late-maturing variety“WS1”were employed as experimental materials.Four seedling age treatments were established at 20,25,30,and 35 d.By measuring the agronomic traits and nutrient content of the stem lettuce,we employed correlation analysis,principal component analysis,cluster analysis,and the membership function method for a comprehensive evaluation.This study aims to elucidate the optimal planting age for stem lettuce in plateau regions.By addressing the issues of inconsistent quality and yield that arise from arbitrary selection of planting age in production,we seek to establish a theoretical foundation for the development of a high-quality and efficient cultivation technology system for this crop.The results of the correlation analysis revealed that a total of 18 pairs of indicators in WS1 exhibited significant correlations,comprising 8 pairs that were positively correlated and 10 pairs that were negatively correlated.In WS120,25 pairs of indicators reached a significant correlation level,with 13 pairs positively correlated and 12 pairs negatively correlated.Principal component analysis identified 14 agronomic traits and 4 quality indicators,which were consolidated into 3 principal components,achieving cumulative contribution rates of 94.068%.Cluster analysis results indicated that WS1 could be categorised into two groups based on different treatments.At 30 d and 35 d,the samples were grouped together due to superior root-related indicators and nutritional components,whereas at 25 d and 20 d,they formed a separate group owing to enhanced agronomic traits.WS120 was classified into Group I,reflecting relatively favourable agronomic traits at 25 d and 20 d.Group II(30 d)was characterised by all indicators falling within the mid-range.Class III(35 d)was distinctly categorised due to elevated levels of vitamin C,soluble sugars,and soluble proteins.A comprehensive evaluation employing the membership function method indicated that the overall performance of WS1 and WS120 under varying treatments was ranked as follows:25 d>30 d>20 d>35 d.It can be utilised directly to inform production practices and holds considerable practical importance for advancing the high-quality and efficient cultivation of stem lettuce,thereby contributing to the growth of the plateau vegetable industry. 展开更多

Jujube(Ziziphus jujuba Mill.)is a fruit crop of high economic value,renowned for its distinctive flavor and wide range of phenotypic diversity.Despite major advancements in jujube genomics,the role of genetic variants in underlying agronomic trait formation is still poorly understood.Here,we used seven high-quality jujube genomes to construct a pan-TE(transposon element)map and investigated how TEs shape genome evolution and agronomic traits.We found that TEs constitute 29.05%30.38%of the genome,predominantly long terminal repeat(LTR)retrotransposons such as Copia and Gypsy.A positive correlation(R2=0.76)between TE content and genome size underscores their role in genomic expansion.TE insertions within gene bodies significantly reduce gene expression,particularly for genes involved in cell wall biosynthesis and glucose metabolism.Population scale analysis of 1041 accessions identified 4176 transposable element insertion polymorphisms(TIPs)that distinguish wild and cultivated groups.Wild jujubes harbor stress-related TiPs(e.g.in peroxidase genes),whereas cultivated accessions carry TiPs linked to fruit development.Notably,a Gypsy insertion upstream of the cellulose synthase gene ZjCESA4 is associated with reduced expression and thinner pericarp in'Dongzao'compared to'Huizao'.Similarly,a downstream LTR/Gypsy insertion near the MADS-box transcription factor gene ZjAGL18 correlates with suppressed expression,highlighting the recurrent targeting of key regulatory genes by TEs during domestication.Our findings demonstrate that TiPs are a major source of genetic variation in jujube,providing molecular markers for breeding programs that aim to balance fruit quality and stress resilience. 展开更多

Pear(Pyrus L.)is a fruit tree of global commercial importance.Its genetic relationships,evolutionary history,dissemination routes,and genetic determinants ofmost agronomic traits remain to be elucidated.We conducted whole-genome resequencing of 495 Pyrus accessions.Phylogenetic and demographic analyses resolved geographic groupings of the accessions,identifying the Yunnan-Guizhou Plateau as the putative dissemination center for cultivated Pyrus pyrifolia and P.bretschneideri.Identification of two evolutionary bottlenecks provides insights into the population dynamics of pear species.Admixture and introgression analyses revealed both intraspecific and interspecific genetic exchanges,substantiating the complex emergence of cultivated populations.Genome-wide association study(GWAS)identified loci associated withnine crucial agronomic traits,together with eight candidate genes.The GWAS,molecular,and biochemical analyses suggested that PbeMADS25,PbeSPP,PbeDHQ-SDH,PbeARF2,PbePPO,PbePIN3,PbeCXE,and PbeMYB38 participate in the regulation of number of stigmas and number of locules,number of stamens,young leaf color,sepal persistence,astringency,acidity,aroma,and fruit skin color,respectively.Overexpression and metabonomic analysis of PbeCXE indicated that it affects the fruit aroma by affecting the balance between ester biosynthesis and substrate consumption.These findings expand our understanding of Pyrus evolution and provide a genomic foundation for genetic improvement of agronomic traits. 展开更多

Medicinal plants are foundational to global health systems,yet their increasing integration into modern pharmaceutical supply chains has intensified sustainability challenges associated with climate change,biodiversity loss,and market volatility.Artemisia annua L.,the sole commercial source of artemisinin—the cornerstone of artemisinin-based combination therapies for malaria—exemplifies these tensions.Despite decades of agronomic and biotechnological research,global artemisinin supply remains unstable,largely due to yield variability,monoculture-driven ecological risks,and socio-economic vulnerabilities faced by smallholder producers.This literature-based review synthesizes advances across agronomy,climate-adaptive breeding,artificial intelligence–enabled precision agriculture,and socio-economic governance to propose an integrated framework for the sustainable expansion of A.annua cultivation.Central to the framework is the repositioning of agrobiodiversity—from a perceived constraint on productivity to a primary mechanism for enhancing ecological resilience,yield stability,and farmer livelihoods.The framework emphasizes biodiversity-centric agronomic practices,multi-latitude phenological adaptation,inclusive intelligent farming systems,and Public–Private–Farmer Partnerships(PPFPs)designed to promote equitable value distribution.While the framework is conceptual in nature,it is grounded in empirical evidence from diverse disciplinary domains.To facilitate translation into practice,a structured roadmap for empirical validation is proposed,outlining multi-location,multi-year field trials integrating agronomic,ecological,and socioeconomic metrics.Collectively,this work provides a systems-level blueprint for stabilizing the global artemisinin supply while aligning medicinal plant production with biodiversity conservation,climate resilience,and social equity objectives. 展开更多

Powdery mildew is a serious disease caused by Blumeria graminis f.sp.tritici(Bgt)that critically threatens the yield and quality of wheat(Triticum aestivum L.).Using effective powdery mildew resistance genes is the optimal method for controlling this disease.Against the background of high genetic homogeneity among the modern commercial cultivars that are mainly derived from conventional interbreeding,the resistance genes from wheat relatives have especially prominent advantages.Octoploid triticale,produced from common wheat and rye(Secale cereale L.)through distant hybridization,is a new synthetic species and valuable gene donor for wheat improvement.In this study,we developed the wheat-rye line YT5 through the hybridization of octaploid triticale and two wheat lines.YT5 was confirmed to be a 6RL ditelosomic addition and 1R(1B)substitution line using genomic in situ hybridization(GISH),multicolor fluorescence in situ hybridization(mc-FISH),multicolor GISH(mc-GISH)and molecular marker analysis.Genetic analysis showed that the powdery mildew resistance in YT5 was derived from the rye chromosome arm 6RL.After inoculation with different Bgt isolates at the seedling stage,YT5 had compound reaction patterns with both obvious spores and hypersensitivity,and it gradually became highly resistant until the adult-plant stage,thus showing a resistance response significantly different from the reported Pm genes from rye chromosome 6RL.YT5 also showed promising agronomic performance,so it is expected to be an elite resistance donor for wheat improvement.To promote the transfer of the chromosome arm 6RL of YT5 in marker-assisted selection(MAS)breeding,we selected and verified two 6RL-specific kompetitive allelespecific PCR(KASP)markers that can be applied to efficiently detect this chromosome arm in different wheat backgrounds. 展开更多

Small signaling peptides,generally comprising fewer than 100 amino acids,act as crucial signaling molecules in cell-to-cell communications.Upon perception by their membrane-localized corresponding receptors or co-receptors,these peptide-receptor modules then(de)activate either long-distance or local signaling pathways,thereby orchestrating developmental and adaptive responses via(post)transcriptional,(post)translational,and epigenetic regulations.The physiological functions of small signaling peptides are implicated in a multitude of developmental processes and adaptive responses,including but not limited to,shoot and root morphogenesis,organ abscission,nodulation,Casparian strip formation,pollen development,taproot growth,and various abiotic stress responses such as aluminum,cadmium,drought,cold,and salinity.Additionally,they play a critical role in response to pathogenic invasions.These small signaling peptides also modulate significant agronomic and horticultural traits,such as fruit size,maize kernel development,fiber elongation,and rice awn formation.Here,we underscore the roles of several small signaling peptide families such as CLE,RALF,EPFL,mi PEP,CEP,IDA/IDL,and PSK in regulating these biological processes.These novel insights will deepen our current understanding of small signaling peptides,and offer innovative strategies for genetic breeding stress-tolerant crops and horticultural plants,contributing to establish sustainable agricultural systems. 展开更多

Epigenetics-mediated breeding(epibreeding)involves engineering crop traits and stress responses through the targeted manipulation of key epigenetic features to enhance agricultural productivity.While conventional breeding methods raise concerns about reduced genetic diversity,epibreeding propels crop improvement through epigenetic variations that regulate gene expression,ultimately impacting crop yield.Epigenetic regulation in crops encompasses various modes,including histone modification,DNA modification,RNA modification,non-coding RNA,and chromatin remodeling.This review summarizes the epigenetic mechanisms underlying major agronomic traits in maize and identifies candidate epigenetic landmarks in the maize breeding process.We propose a valuable strategy for improving maize yield through epibreeding,combining CRISPR/Cas-based epigenome editing technology and Synthetic Epigenetics(SynEpi).Finally,we discuss the challenges and opportunities associated with maize trait improvement through epibreeding. 展开更多

Banana breeding is hampered by the very low fertility of domesticated bananas and the lack of knowledge about the genetic determinism of agronomic traits.We analysed a breeding population of 2723 triploid hybrids resulting from crosses between diploid and tetraploid Musa acuminata parents,which was evaluated over three successive crop cycles for 24 traits relating to yield components and plant,bunch,and fruit architectures.A subset of 1129 individuals was genotyped by sequencing,revealing 205612 single-nucleotide polymorphisms(SNPs).Most parents were heterozygous for one or several large reciprocal chromosomal translocations,which are known to impact recombination and chromosomal segregation.We applied two linear mixed models to detect associations between markers and traits:(i)a standard model with a kinship calculated using all SNPs and(ii)a model with chromosome-specific kinships that aims at recovering statistical power at alleles carried by long non-recombined haplotypic segments.For 23 of the 24 traits,we identified one to five significant quantitative trait loci(QTLs)for which the origin of favourable alleles could often be determined amongst the main ancestral contributors to banana cultivars.Several QTLs,located in the rearranged regions,were only detected using the second model.The resulting QTL landscape represents an important resource to support breeding programmes.The proposed strategy for recovering power at SNPs carried by long non-recombined rearranged haplotypic segments is an important methodological advance for future association studies in banana and other species affected by chromosomal rearrangements. 展开更多

Alfalfa(Medicago sativa L.),a perennial legume forage,has been broadly cultivated owing to a variety of favorable characteristics,including comprehensive ecological adaptability,superior nutritive value and palatability,and nitrogen fixation capacity.The productivity traits of alfalfa,specifically its biomass yield and forage quality,are significantly influenced by a series of determinants,including internal developmental factors and external environmental cues.However,the regulatory mechanisms underlying the fundamental biological problems of alfalfa remain elusive.Here,we conducted a comprehensive review focusing on the genomics of alfalfa,advancements in gene-editing technologies,and the identification of genes that control pivotal agronomic characteristics,including biomass formation,nutritional quality,flowering time,and resistance to various stresses.Moreover,a molecular design roadmap for the‘ideal alfalfa’has been proposed and the potential of pangenomes,self-incompatibility mechanisms,de novo domestication,and intelligent breeding strategies to enhance alfalfa’s yield,quality,and resilience were further discussed.This review will provide comprehensive information on the basic biology of alfalfa and offer new insights for the cultivation of ideal alfalfa. 展开更多

Cherries are one of the economically important fruit crops in the Rosaceae family,Prunus genus.As the first fruits of the spring season in the northern hemisphere,their attractive appearance,intensely desirable tastes,high nutrients content,and consumer-friendly size captivate consumers worldwide.In the past 30 years,although cherry geneticists and breeders have greatly progressed in understanding the genetic and molecular basis underlying fruit quality,adaptation to climate change,and biotic and abiotic stress resistance,the utilization of cherry genomic data in genetics and molecular breeding has remained limited to date.Here,we thoroughly investigated recent discoveries in constructing genetic linkage maps,identifying quantitative trait loci(QTLs),genome-wide association studies(GWAs),and validating functional genes of edible cherries based on available de nouo genomes and genome resequencing data of edible cherries.We further comprehensively demonstrated the genetic architecture of the main agronomic traits of edible cherries by methodically integrating QTLs,GWAs loci,and functional genes into the identical reference genome with improved annotations.These collective endeavors will offer new perspectives on the availability of sequence data and the construction of an interspecific pangenome of edible cherries,ultimately guiding cherry breeding strategies and genetic improvement programs,and facilitating the exploration of similar traits and breeding innovations across Prunus species. 展开更多

High molecular weight glutenin subunits(HMW-GS),major components of seed storage proteins in wheat,have large effects on processing quality.GLU-1 genes encode HMW-GS and their expression is mainly controlled at the transcriptional level by interactions between cis-regulatory elements and transcription factors.We previously identified an Aux/IAA transcription factor TaIAA10-6D that bound to a conserved cis-regulatory module CCRM1-1,the most essential conserved cis-regulatory module in GLU-1.Here,we confirmed the binding of TaIAA10-6D to CCRM1-1 using yeast one hybrid and dualluciferase reporter assays.The enhanced expression of TaIAA10-6D suppressed glutenin accumulation and increased gliadin content.Dynamic transcriptome analyses revealed that TaIAA10-6D overexpression down-regulated glutenin and gliadin genes during an early stage of grain filling,but up-regulated gliadin genes during a late stage probably by endoplasmic reticulum stress,accounting for its effect on the tradeoff between glutenin and gliadin.Rheological property and processing quality assays showed that TaIAA10-6D overproduction reduced stabilization time and bread quality,but enhanced cookie quality.Overexpression of TaIAA10-6D also reduced plant height,leaf size,kernel number and grain yield.We identified two major haplotypes of TaIAA10-6D,Hap I and Hap II,and developed a breeding-friendly diagnostic marker.Hap I conferred higher expression of TaIAA10-6D and concomitantly reduced plant height and kernel number,but had little effect on grain yield,contributing to lodging resistance without yield penalty.Hap I was subjected to positive selection in breeding.The findings provide a useful gene for wheat improvement and broaden insights into the regulatory machinery underpinning auxin-mediated quality formation,plant morphogenesis and yield gain. 展开更多
