7、構(gòu)對(duì)其產(chǎn)量和品質(zhì)均有重要影響.對(duì)花器官形態(tài)結(jié)構(gòu)及發(fā)育機(jī)理的研究有助于提高水稻產(chǎn)量并改良其品質(zhì).花器官的形成和發(fā)育是水稻從營養(yǎng)生長(zhǎng)轉(zhuǎn)向生殖生長(zhǎng)的重要過程,其發(fā)育模式和分子機(jī)理,一直是生物學(xué)研究的熱點(diǎn)和焦點(diǎn).水稻小穗的穎殼是禾本科特有的器官,主要包括內(nèi)外稃、護(hù)穎和副護(hù)穎,關(guān)于其起源和形成的分子機(jī)制還知之甚少.近些年對(duì)穎殼的研究不斷深入,不僅有助于深入認(rèn)識(shí)水稻小穗或花器官的發(fā)育,而且能系統(tǒng)地了解水稻小穗或花器官發(fā)育的整個(gè)調(diào)控網(wǎng)絡(luò).本文主要介紹了水稻小穗穎殼發(fā)育的相關(guān)進(jìn)展及植
