Os04g0598300

The rice gene Os04g0598300 was reported as APO2 in 2012 by researchers from Japan.

Annotated Information

Function

• The rice aberrant panicle organization 2 (apo2) mutant which exhibits small panicles with reduced number of primary branches due to the precocious formation of spikelet meristems. The apo2 mutants also display a shortened plastochron in the vegetative phase, late flowering, aberrant floral organ identities and loss of floral meristem determinacy.

• APO2/RFL and APO1, the rice ortholog of Arabidopsis UNUSUAL FLORAL ORGANS, act cooperatively to control inflorescence and flower development.

• APO2/RFL plays a role in suppressing the transition to spikelet meristems.
