 * 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.

	* In the reproductive phase, APO2/RFL was expressed in the meristems of primary and secondary branches at primordial and elongating stages (Figure 5b,c), but the expression transiently downregulated from the meristems at stage In5 (Figure 5d). When spikelets were differentiated, APO2/RFL expression was recovered in floral meristems and in primordia of all floral organs, including lodicules, stamens, carpels and ovules (Figure 5e–h). This unique expression pattern during the reproductive phase has not been reported to date. Since the timing of the downregulation coincided with that of the meristem identity change from inflorescence to spikelet and the mutant inflorescence phenotypes seemed to be independent from those in spikelets/flowers, APO2/RFL may independently function between inflorescence and the spikelet/flower stages.		* In the reproductive phase, APO2/RFL was expressed in the meristems of primary and secondary branches at primordial and elongating stages (Figure 5b,c), but the expression transiently downregulated from the meristems at stage In5 (Figure 5d).

-* In the vegetative phase, APO2/RFL was expressed in shoot meristems and leaf primordia (Figure 5a), in contrast to the result of Kyozuka et al. (1998) who did not detect the expression in the vegetative meristems. Because apo2 mutants exhibited several phenotypes in vegetative phase, the expression in shoot apical meristems would be reasonable.
