During anther development,the transformation of the microspore into mature pollen occurs under the pro-tection of first the tetrad wall and later the pollen wall.Mutations in genes involved in this wall transition often lead to microspore rupture and male sterility;some such mutants,such as the reversible male sterile(rvms)mutant,are thermo/photoperiod-sensitive genic male sterile(P/TGMS)lines.Previous studies have shown that slow development is a general mechanism of P/TGMS fertility restoration.In this study,we iden-tified restorer of rvms-2(res2),which is an allele of QUARTET3(QRT3)encoding a polygalacturonase that shows delayed degradation of the tetrad pectin wall.We found that MS188,a tapetum-specific transcrip-tion factor essential for pollen wall formation,can activate QRT3 expression for pectin wall degradation,indicating a non-cell-autonomous pathway involved in the regulation of the cell wall transition.Further as-says showed that a delay in degradation of the tetrad pectin wall is responsible for the fertility restoration of rvms and other P/TGMS lines,whereas early expression of QRT3 eliminates low temperature restoration of rvms-2 fertility.Taken together,these results suggest a likely cellular mechanism of fertility restoration in P/TGMS lines,that is,slow development during the cell wall transition of P/TGMS microspores may reduce the requirement for their wall protection and thus support their development into functional pollens,leading to restored fertility. 展开更多
