egulation of juvenile-adult phase change in rice

揭示了pps突变体幼期延长的致病基因编码拟南芥COP1同源基因。由于COP1与幼体-成体相变无关，水稻PPS在进化过程中获得了一种新的功能。突变前的幼期缩短。PRE编码一种参与茉莉酸生物合成的酶。我们还分离到了MORI1基因。此外，粳稻和籼稻类群在幼成虫期变化的时间上也存在差异。

Causal gene of pps mutant showing elongated juvenile phase was revealed to encode an ortholog of Arabidopsis COP1. Since COP1 is not associated with juvenile-adult phase change, rice PPS has acquired a novel function during evolution. Juvenile phase of pre mutant is shortened. PRE encodes an enzyme involved in jasmonate biosynthesis. We also isolated MORI1 gene. In addition, japonica and indica groups were revealed to have diversified in the timing of juvenile-adult phase change.
