Progress Analysis of Long Noncoding RNAs(lncRNAs) in Plants

Gao Chengxiang;Deng Fenni;Shen Fafu;Weifang Nersing Vocational College;College of Agronomy, Shandong Agricultural University;  
Long noncoding RNAs(lncRNAs) are defined as RNA genes longer than 200 bp in length that have no apparent coding function. Lnc RNA can be divided into 5 groups based on the relative location of the genome source and the coding gene of neighboring proteins:(1) sense long non-coding RNA;(2) antisense transcripts(NATs) derived from introns;(3) intergenic non-coding(nc) RNAs(linc RNAs);(4) intronic nc RNAs(incRNAs);(5) bidirectional long nc RNA. LncRNAs may execute their functions via numerous mechanisms, including activating, gathering or transporting proteins to produce epigenetic silencing and repression, modifying promoter activities by nucleosome repositioning, and regulating the level of DNA methylation and histone modifications to produce epigenetic modification. Compared with m RNA, lncRNAs has the specificity of plant tissue expression Plant lncRNAs are involved in different metabolic pathways, and are associated with various biological functions.
