Webb26 juni 2013 · In this study, at least 864 and 3,961 loci generating 21-nt and 24-nt phased siRNAs (phasiRNAs),respectively, were identified in three tissues from wild rice. Of these phasiRNA-producing loci, or PHAS genes, biogenesis of phasiRNAs in at least 160 of 21-nt and 254 of 24-nt loci could be triggered by interaction with miRNA (s). WebbPhased small-interfering RNAs (phasiRNAs) may be the newest member discovered in recent years. The photoperiod-sensitive male sterility (PSMS) rice is a very valuable germplasm that started the era of two-line hybrid rice. Here we show that phasiRNAs generated by a long-noncoding RNA PMS1T encoded by the Pms1 locus regulates PSMS …

WebbMoreover, we noticed that 21-nt phasiRNAs are more enriched in rice compared to 24-nt phasiRNAs across various rice tissues. Similar to miRNAs, the 21-nt phasiRNAs negatively regulate their target genes by cleaving mRNAs in complementary region at the post-transcriptional level [ 14, 28 ]. dutch chain storesWebb3 juni 2013 · In this study, at least 864 and 3,961 loci generating 21-nt and 24-nt phased siRNAs (phasiRNAs),respectively, were identified in three tissues from wild rice.

As shown in Figure 1c (Table S3), rice miR167 targets ARF6 gene (LOC_Os02g06910) and incites the production of abundant 21-nt phasiRNAs in non-reproductive tissues (i.e., leaves). Interestingly, the same gene can produce 24-nt phasiRNAs over the same region after miR167 cleavage site in rice anther (Figure 1c and … dutch chamber of commerce swedenWebb28 okt. 2024 · In grasses, two types of phased, small interfering RNAs (phasiRNAs) are expressed largely in young, developing anthers.
