▶ AI Summary
The study performed integrative small RNA sequencing and transcriptomic profiling across ten anther developmental stages of Kitaake rice to map sRNA‑related gene expression and phasiRNA production. It uncovered previously undescribed post‑meiotic 21‑nt and 24‑nt phasiRNA loci with distinct accumulation patterns and nucleotide compositions, suggesting diverse biogenesis mechanisms and specialized roles in pollen development.
