Distinct classes of 21 and 24-nt phasiRNAs suggest diverse mechanisms of biogenesis and function in rice anther development

Abstract PhasiRNAs (phased small interfering RNAs) are a major class of plant small RNAs known to be key regulators in male reproductive development of maize (Zea mays) and rice (Oryza sativa), among other plants. Earlier research focused primarily on premeiotic 21-nt phasiRNAs and meiotic 24-nt phasiRNAs, while new studies uncovered a premeiotic class of 24-nt phasiRNAs. The biogenesis and function of these phasiRNAs remain unclear.

Abstract PhasiRNAs (phased, small interfering RNAs) play a crucial role in supporting male fertility in grasses. Earlier work in maize (Zea mays) and rice (Oryza sativa) - and subsequently many other plant species - identified premeiotic 21-nt and meiotic 24-nt phasiRNAs. More recently, a group of premeiotic 24-nt phasiRNAs were discovered in the anthers of two Pooideae species, barley (Hordeum vulgare) and bread wheat (Triticum aestivum).

Abstract PhasiRNAs (phased, small interfering RNAs) play a crucial role in supporting male fertility in maize (Zea mays), rice (Oryza sativa), and bread wheat (Triticum aestivum). Disruption of their biogenesis or function can induce conditional male sterility.
