WebbphasiRNA triggers. 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 … Webb2 Dynamic changes of small RNAs in rice spikelet development reveal specialized reproductive phasiRNA .. 来源：J EXP BOT( P 0022-0957 E 1460-2431 ) 发表时间: 2016/11. ... 3 Dynamic changes of small RNAs in rice spikelet development reveal specialized reproductive phasiRNA ..

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 ]. WebbIn rice, MULTIPLE SPOROCYTES1 (MSP1), a leucine-rich-repeat receptor kinase, plays an important role in anther development by limiting the number of sporocytes. OsTDL1a (a …

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 …
Webb16 aug. 2024 · The spatiotemporal pattern of 21 nt phasiRNAs in male reproductive tissues has been well-described in maize and rice 2, 4. These reproductive, 21 nt phasiRNAs lack … Webb15 okt. 2024 · Here we profile phasiRNA expression in premeiotic and meiotic spikelets as well as in purified male meiocytes at early prophase I, tetrads and microspores in rice. We show that 21-nt phasiRNAs are most abundant in meiocytes at early prophase I while 24-nt phasiRNAs are more abundant in tetrads and microspores.
WebbIn summary, sequencing data revealed the developmental modulation of phasiRNA biogenesis in rice anthers, with 24-phasiRNAs and their precursors disrupted in the …
Webb12 feb. 2024 · In rice anthers, MEL1-associating small interfering RNAs (masiRNAs) were composed of large amounts of premeiotic 21-nt phasiRNAs, plus low levels of both 24-nt repeat-associated siRNA and meiotic 24-nt phasiRNAs. Production of 24-nt phasiRNA during the meiotic stage was largely EAT1-dependent. michael brennan wells fargoWebbAbstract. Plant miRNAs can trigger the production of phased, secondary siRNAs from either non-coding or protein-coding genes.
