As an evolutionarily conserved microRNA(miRNA),miR396 regulates plant growth by integrating developmental and environmental signals.In the present study,CsaWPRa4,a WEB1(Weak Chloroplast Movement under Blue Light 1)/PMI2(Plastid Movement Impaired 2)-related protein(WPR)family member,was predicted to be a novel target gene of CsamiR396 in cucumbers.WPRa4 is a highly conserved protein in plants.Interestingly,bioinformatic analysis showed that WPRa4 acts as a conserved target gene ofmiR396 in cucumber and its related species in cucurbits,but not in other plants.ThemiR396 binding site is located within the coding region of the AAK(K/R)AVE motif in WPRa4,and it evolved by synonymous substitutions in cucurbits.Negative regulation of CsaWPRa4 by CsamiR396 was confirmed by reverse transcription-quantitative polymerase chain reaction(RT-qPCR),luciferase assay,gene overexpression,and tobacco ringspot virus(TRSV)-based gene silencing analysis.The subcellular localization assay showed that CsaWPRa4 was localized to both the cell periphery and nuclear periphery.Thereafter,Csawpra4 mutants were generated using CRISPR/Cas9-mediated gene editing.Chloroplast-and flower morphogenesis-related genes were altered,resulting in altered photosynthetic traits and flower morphogenesis in Csawpra4 mutants.In summary,our results showed that WPRa4 evolved as a novel target ofmiR396 through synonymous substitutions in cucurbits,uncovering the role of synonymous substitutions in genome evolution and providing a new perspective on miRNA-target evolutionary processes in plants. 展开更多

The study of synonyms based on corpus has become a hot topic in recent years,and the task of differentiating synonyms has always been a complex issue.The current study made an attempt to investigate the differences among English noun synonyms“opposition”,“resistance”and“defiance”from the perspective of frequency distribution,collocation and semantic prosody based on COCA.This research shows that in terms of frequency distribution,“opposition”and“resistance”are more frequently used than“defiance”.Both of the two are most commonly used in academic journals while“defiance”is most frequently used in fiction.All of these three words rarely appear in TV and movie subtitles.Second,from the perspective of collocation,“opposition”often collocates with words about politics and personal state,“resistance”usually appears with words concerning politics and medicine,and“defiance”mainly shows up in the fields of military,medicine,personal state and others.Third,from the dimension of semantic prosody,“opposition”presents negative semantic prosody,“resistance”has neutral semantic prosody,and“defiance”indicates mixed semantic prosody.The present study is able to enrich the relevant study on synonym differentiation,and highlight the importance of understanding the subtle differences among synonyms. 展开更多

Apple（Malus×domestica） has been proposed as an important woody plant and the major cultivated fruit trees in temperate regions. Apple whole genome sequencing has been completed, which provided an excellent opportunity for genome-wide analysis of the synonymous codon usage patterns. In this study, a multivariate bioinformatics analysis was performed to reveal the characteristics of synonymous codon usage and the main factors affecting codon bias in apple. The neutrality, correspondence, and correlation analyses were performed by Codon W and SPSS（Statistical Product and Service Solutions） programs, indicating that the apple genome codon usage patterns were affected by mutational pressure and selective constraint. Meanwhile, coding sequence length and the hydrophobicity of proteins could also influence the codon usage patterns. In short, codon usage pattern analysis and determination of optimal codons has laid an important theoretical basis for genetic engineering, gene prediction and molecular evolution studies in apple. 展开更多

For protecting the copyright of a text and recovering its original content harmlessly,this paper proposes a novel reversible natural language watermarking method that combines arithmetic coding and synonym substitution operations.By analyzing relative frequencies of synonymous words,synonyms employed for carrying payload are quantized into an unbalanced and redundant binary sequence.The quantized binary sequence is compressed by adaptive binary arithmetic coding losslessly to provide a spare for accommodating additional data.Then,the compressed data appended with the watermark are embedded into the cover text via synonym substitutions in an invertible manner.On the receiver side,the watermark and compressed data can be extracted by decoding the values of synonyms in the watermarked text,as a result of which the original context can be perfectly recovered by decompressing the extracted compressed data and substituting the replaced synonyms with their original synonyms.Experimental results demonstrate that the proposed method can extract the watermark successfully and achieve a lossless recovery of the original text.Additionally,it achieves a high embedding capacity. 展开更多

In this study,a comparative analysis of the codon usage bias was performed in Aeropyrum pernix K1 and two other phylogenetically related Crenarchaeota microorganisms(i.e.,Pyrobaculum aerophilum str.IM2 and Sulfolobus acidocaldarius DSM 639).The results indicated that the synonymous codon usage in A.pernix K1 was less biased,which was highly correlated with the GC3s value.The codon usage patterns were phylogenetically conserved among these Crenarchaeota microorganisms.Comparatively,it is the species function rather than the gene function that determines their gene codon usage patterns.A.pernix K1,P.aerophilum str.IM2,and S.acidocaldarius DSM 639 live in differently extreme conditions.It is presumed that the hving environment played an important role in determining the codon usage pattern of these microorganisms.Besides,there was no strain-specific codon usage among these microorganisms.The extent of codon bias in A.pernix K1 and S.acidocaldarius DSM 639 were highly correlated with the gene expression level,but no such association was detected in P.aerophilum str.IM2 genomes. 展开更多

The evolutionary suppression of synonymous codon sites is a controversial topic. Although some studies have indicated that synonymous substitution is under positive selection, most of these studies relied on comparison of homologous genes and/or a limited number of sequences. In the present work, we compared the selection strength at synonymous sites for two types of protein-encoding genes： genes encoding enzymes and protein genes encoding non-enzymes. Our method does not require assumptions concerning, for example, evolutionary equilibrium or population size. We compared -70 000 genes from the fully sequenced mammalian Homo sapiens, Pan troglodytes, Mus musculus, and Rattus norvegicus genomes and found that the percentage of C and G in the third position of a codon positively correlates with the percentage of the G/C content within 4- 20 ooo nucleotides of the gene. More interestingly, we found that synonymous sites in mammalian genes encoding enzymes have undergone stronger selection than did such sites in genes encoding proteins that are not enzymes. 展开更多

Objective:Autosomal dominant polycystic kidney disease(ADPKD)is mainly caused by the pathogenic mutation of PKD1 or PKD2 gene and usually affects bilateral kidneys.Synonymous mutations are generally assumed to be neutral as they do not alter amino acids.Herein,we described an extremely rare ADPKD child caused by a heterozygous synonymous mutation of PKD2 gene accompanied by massive proteinuria and congenital solitary kidney.Methods:Clinical characteristics of the patients were summarized.Whole-exome sequencing was performed to screen the disease-causing gene mutation,and reverse transcription polymerase chain reaction(RT-PCR)and Sanger sequencing were applied to analyze the impact of the identified mutation on gene transcription and splicing.Results:Polycystic changes were found in the solitary kidney of a girl initially presented with nephrotic-range proteinuria.Thereafter her mother and 2 other family members were diagnosed to be ADPKD.Whole-exome sequencing of the proband identified a heterozygous synonymous mutation(c.1716G>A,p.Lys572=)located in the splicing site of exon 7 in PKD2 gene,which was co-segregated with the PKD phenotype in the family.RT-PCR and direct sequencing of amplified products revealed that this heterozygous synonymous mutation led to exon7 skipping in PKD2 gene.Conclusion:We reported an extremely rare child case of ADPKD2 in combination with solitary kidney and nephrotic-range proteinuria,and firstly confirmed the pathogenicity of a heterozygous synonymous mutation(c.1716G>A)in PKD2 gene.The results indicate that synonymous mutations should not be excluded from disease-causing if they are located in splicing site of an exon. 展开更多

Word similarity(WS)is a fundamental and critical task in natural language processing.Existing approaches to WS are mainly to calculate the similarity or relatedness of word pairs based on word embedding obtained by massive and high-quality corpus.However,it may suffer from poor performance for insufficient corpus in some specific fields,and cannot capture rich semantic and sentimental information.To address these above problems,we propose an enhancing embedding-based word similarity evaluation with character-word concepts and synonyms knowledge,namely EWS-CS model,which can provide extra semantic information to enhance word similarity evaluation.The core of our approach contains knowledge encoder and word encoder.In knowledge encoder,we incorporate the semantic knowledge extracted from knowledge resources,including character-word concepts,synonyms and sentiment lexicons,to obtain knowledge representation.Word encoder is to learn enhancing embedding-based word representation from pre-trained model and knowledge representation based on similarity task.Finally,compared with baseline models,the experiments on four similarity evaluation datasets validate the effectiveness of our EWS-CS model in WS task. 展开更多

In this work,an approach is proposed to acquire synonymous attribute phrases of named entities(NEs) from an online encyclopedia.Synonymous attribute phrases are the phrases that express the same attribute with different surface forms for a class of NEs.Specifically,the proposed approach is composed of three stages.Firstly,the entries related to a given NE class are automatically selected from an online encyclopedia.Secondly,attribute phrases are extracted based on the statistics of phrase frequency.Thirdly,synonymous attributes are identified in a pairwise manner through a classification framework combining multiple features.The proposed approach is applied on Baidu Baike,a Chinese online encyclopedia,for four different NE classes.Experimental results show that the approach obtains an average precision of 74%and an average F-value of 65%for the four NE classes.In particular,thousands of synonymous attribute phrase pairs are acquired for each class,which demonstrates the effectiveness of the proposed approach. 展开更多

Goel and two related Euryarchaeota microorganisms （Picrophilus torridus str. DSM 9790 and Natronomonas pharaonis str. DSM 2160）. Results revealed that synonymous codon usage in Methanosarcina mazei str. Goel was less biased, which was highly correlated with the GC3S value. And the codon usage patterns were phylogenetically conserved among those Euryarchaeota microorganisms. By employing a hierarchical clustering analysis, it can be seen that it is more the species than the gene function that determines their gene codon usage pattems. Considering that those microorganisms live in different environments where the pH conditions vary quite a lot, it can be presumed that their living environments, especially the pH conditions, play an important role in determining those microorganisms＇ codon usage pattems. 展开更多

With the verification of the type specimen by six experts from the Nanjing Institute of Geology and Palaeontology, the specimen of Xianfengella prima He and Yang, 1982 described by Qian （Qian, 2001, flge2： la-c） is confirmed to be the holotype specimen （NIGP. 84430） of Yangtzedonta primitiva Yu, 1985, and consequently, Yu Wen＇s view that they are not the same specimen is impractical. This fact demonstrates that Yangtzedonta primitiva Yu, 1985 is undoubtedly a junior synonym of Xianftngella prima He and Yang, 1982, and is invalid.

To investigate how synonymous codons have been adapted to the formation of ribonucleic acid(RNA)G-quadruplex(rG4)structure,a computational searching algorithm G4Hunter was applied to detect rG4 structures in protein-coding sequences of mRNAs in five eukaryotic species.The native sequences forming rG4s were then compared with randomized sequences to evaluate selection on synonymous codons.Factors that may influence the formation of rG4 were also investigated,and the selection pressures of rG4 in different gene regions were compared to explore its potential roles in gene regulation.The results show universal selective pressure acts on synonymous codons in rG4 regions to facilitate rG4 formation in five eukaryotic organisms.While G-rich codon combinations are preferred in the rG4 structural region,C-rich codon combinations are selectively unfavorable for rG4 formation.Gene's codon usage bias,nucleotide composition,and evolutionary rate can account for the selective variations on synonymous codons among rG4 structures within a species.Moreover,rG4 structures in the translational initiation region showed significantly higher selective pressures than those in the translational elongation region. 展开更多

Synonym differentiation has always been a difficulty in English learning. Traditionally, definitions and examples from dictionaries are taken to illustrate shades of differences between synonyms, which fails to provide a comprehensive description of these differences for students to differ synonyms. However, with the large volume, authentic materials, fast and convenient retrieval provided by corpus, the corpus-based synonym differentiation method can make a comprehensive description of synonyms in terms of their distinctive features in frequency distribution, collocation, colligation and semantic prosody. A corpus-based method will be employed to analyze the differences among the three English synonyms"conquer""overcome"and"surmount"based on the data collected from COCA (Corpus of Contemporary American English), so as to throw new light on synonym differentiation, offering a new way to study synonyms, and to provide references for lexical teaching and second language acquisition. 展开更多
