Description The gene PLA2, also named LHD2, encodes a RNA binding protein which regulate the
time interval between leaf initiation (called plastochron) in rice. It is the
rice orthologue of maize TERMINAL EAR1(TE1). Expression of PLA2 is mainly
observed in shoot apical meristem,and floral meristems, floral organs thrughout
the reproduvtive stages. The mutants show several phenotypes including shortened
plastochron, dwarfism, the reduction of leaf size/tiller number, acceleration of
leaf maturation and ectopic shoot formation at the reprductive phase. Microarray
analysis suggests PLA2 may regulate plastochron and other phenotypes through
KNOX signaling and cytokinin/auxin metabolism in the meristem.
