| 1 | Conservation analysis of long non-coding RNAs in plants显示文摘Long non-coding RNAs(lncRNAs) are gene regulators that have vital roles in development and adaptation to the environment in eukaryotes. However, the structural and evolutionary analyses of plant lncRNAs are limited. In this study, we performed an analysis of lncRNAs in five monocot and five dicot species. Our results showed that plant lncRNA genes were generally shorter and had fewer exons than protein-coding genes. The numbers of lncRNAs were positively correlated with the numbers of protein-coding genes in different plant species, despite a high range of variation. Sequence conservation analysis showed that the majority of lncRNAs had high sequence conservation at the intra-species and sub-species levels, reminiscent of protein-coding genes. At the inter-species level, a subset of lncRNAs were highly diverged at the nucleotide level, but conserved by position.Interestingly, we found that plant lncRNAs have identical splicing signals, and those which can form precursors or targets of miRNAs have a conservative identity in different species. We also revealed that most of the lowly expressed lncRNAs were tissue-specific, while those highly conserved were constitutively transcribed. Meanwhile, we characterized a subset of rice lncRNAs that were co-expressed with their adjacent protein-coding genes, suggesting they may play cis-regulatory roles. These results will contribute to understanding the biological significance and evolution of lncRNAs in plants. | Pingchuan Deng Shu Liu Xiaojun Nie Song Weining Liang Wu | 2018 | Science China(Life Sciences)2018，61，2： | 4 |

| 7 | Patterns and impacting factors of gene evolutionary rate between wild and cultivated emmer wheat(Triticum turgidum)显示文摘Tetraploid emmer wheat(Triticum turgidum L.,BBAA)is the founder progenitor of bread wheat,providing the valuable genetic resource and gene pool for wheat improvement.However,the evolutionary trajectory of tetraploid wheat,especially the evolutionary fate of different types of genes has not been well studied.In this study,the rate of non-synonymous substitution(dN)and synonymous substitution(dS)was calculated by comparing the orthologs between the wild emmer and cultivated durum wheat at the whole genome and subgenome levels to obtain the positively selected genes(PSGs)and negatively selected genes(NSGs).Then,mutation rate,gene length,exon number,GC content,codon bias,and expression level were comprehensively investigated and compared between the PSGs and NSGs.Within both wild emmer and cultivated durum wheat,PSGs between A and B subgenome displayed shorter gene and exon lengths as well as fewer exon numbers compared with NSGs,whereas from wild emmer to cultivated durum wheat,PSGs showed longer gene length and more exon numbers.Furthermore,PSGs displayed much higher expression levels and stronger codon usage bias,but lower genetic diversity compared with NSGs.Finally,two PSGs TdER1-6B,and TdLC7-2A,were found to play the crucial roles in regulating grain width and plant height of tetraploid wheat,respectively.This study systematically investigated the evolutionary,structural,and functional difference between PSGs and NSGs in tetraploid wheat,which will contribute to a better understanding of the selective mode and evolutionary trajectory during wheat domestication and evolution. | Peng-Zheng Lei Qi Ai Zhu-Pei Xiong Jia-Nan Lu Xiu-Lan Wei Weining Song Xiao-Qin Liu Xiao-Jun Nie | 2023 | Journal of Systematics and Evolution2023，61，2： | 0 |
