Dicer-like 5 deficiency confers temperature-sensitive male

Index

Abstract

Small RNAs play crucial roles in plant development. Dicer-like 5 (DCL5) is implicated in generating 24-nt phased secondary small interfering RNAs (phasiRNAs) in monocots, particularly abundant in meiotic anthers. This study characterized *dcl5* mutants in maize, revealing their lack of 24-nt phasiRNAs, defective tapetal cells, and temperature-sensitive male sterility. DCL5 and 24-nt phasiRNAs are deemed essential for fertility under optimal yield conditions.
