Double-stranded RNA interference of a rice PI/GLO paralog, OsMADS2, uncovers its second-whorl-specific function in floral organ patterning.
Unlike many eudicot species, grasses have duplicated PI/GLO-like genes. Functional analysis of one of the rice PI/GLO paralogs, OsMADS2, is reported here. Our data demonstrate its essential role in lodicule development and implicate the second PI/GLO paralog, OsMADS4, to suffice for stamen specification. We provide the first evidence for differential contributions of grass PI/GLO paralogs in patterning second- and third-whorl floral organs.
