WebBy summing phasiRNA abundances from each PHAS locus, we obtained the overall phasiRNA abundances for both 21- and 24-nt phasiRNAs. In wild-type rice spikelets, the overall abundance of 21-nt phasiRNAs was ~120 000 RP5M in stage 3, increasing by >10-fold in stage 5, and then decreasing by <30% in stage 7 ( Fig. 3C ). WebMay 16, 2024 · The phasiRNAs can originate both from protein-coding and non-coding sequences such as transposable elements (TEs) and repetitive DNA. Overall, it can be concluded that the tasiRNA is a type of phasiRNA. The phasiRNAs derived from the nucleotide binding site-leucine-rich repeat (NBS-LRR) disease resistance genes regulate …
