Abstract excerpt

Flavonols have been implicated in male sterility and pollen tube growth for over three decades; however, the molecular mechanisms mediating their accumulation in pollen grains remain poorly understood. In this study, a multidrug and toxic compound extrusion (MATE) transporter, OsMATE7, was identified as a key regulator of flavonol accumulation in mature pollen grains, thereby promoting pollen tube growth in rice...
