From: Introns targeted by plant microRNAs: a possible novel mechanism of gene regulation
Certain transcription form (s) of a rice gene could escape from the regulation of a specific microRNA (miRNA). (A) The 17th intron of LOC_OS01G07330.3, which does not exist in LOC_OS01G07330.1, LOC_OS01G07330.2 and LOC_OS01G07330.4, is regulated by osa-miR2123a/b/c. (B) The 2nd introns of LOC_OS06G24594.2, LOC_OS06G24594.5 and LOC_OS06G24594.6 were regulated by osa-miR446, whereas LOC_OS06G24594.3 and LOC_OS06G24594.4 lacking the corresponding binding site escaped from this regulation. (C) For the five transcription forms of LOC _OS11G07060, only LOC_OS11G07060.2 with a miRNA binding site within its 1st intron was regulated by osa-miR2123a/b/c. From (A) to (C), the introns containing miRNA binding sites (denoted by green vertical lines) were marked by orange boxes. The intron IDs and the miRNAs are listed. The graphic presentations of the transcription forms were retrieved from the rice genome annotation project (TIGR rice) (Yuan et al. 2003).
