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. | ||||||
Curator Comment | Although pla1 and pla2 mutants showed similar phenotypes, results from double mutants and expression patterns suggested PLA1 and PLA2 genes act in the independent pathways to regulate leaf initiation and maturation in rice. |
