(Submitter supplied) Anthers are the male reproductive floral organs, but loss of the 24-nt class of phased small-interfering RNAs (phasiRNAs) may confer temperature-sensitive male sterility in maize. 24-nt phasiRNAs from 176 loci are abundant coordinately in fertile maize anthers after the last periclinal divisions are complete, all four wall layers are formed, and meiosis has initiated in the pollen mother cells. In this study, we found male sterile maize ms23, ms32, and bhlh122 mutants with various degrees of tapetal defects lack 24-PHAS mRNA precursors and 24-nt phasiRNAs, which were not affected in another male sterile mutant, bhlh51. more...
