图2 植物体内长链非编码RNA (lncRNA)的作用机制 (A) lncRNA参与染色质修饰; (B) lncRNA作为诱饵与转录调节子结合; (C) lncRNA作为小分子非编码RNA (sRNA)前体; (D) lncRNA编码产生小多肽顺式或反式调控目标基因; (E) lncRNA作为竞争性内源RNA抑制体内miRNA的积累; (F) lncRNAs调控染色质环的形成

Figure 2 Representative models for the roles of plant long non-coding RNA (lncRNA) (A) lncRNAs mediate the coordinated switching of chromatin states; (B) lncRNAs act as a bait by binding to transcriptional regulators; (C) lncRNAs act as precursors of sRNA; (D) lncRNAs can translated into small peptides to regulate target genes in cis or in trans; (E) lncRNAs act as a target mimic for miRNA; (F) lncRNAs regulate the formation of chromatin loops
