简介：在米饭的Phytochromes被由三个成员，PHYA，PHYB，和PHYC组成的一个基因家庭编码。通过以photomorphogenesis描绘phytochrome异种和野类型(WT)，单个phytochromes的角色preliminarily在调整米饭de青白化，flowering时间和富饶被探索了。然而，很少信息都没关于是否或怎么被报导phytochromes在米饭影响叶绿素生合成和叶绿体开发。在这研究，我们比较了野类型和phyA的叶绿素内容，在任何一个白人光(WL)下面成年或红的phyB和phyAphyB异种点亮(R)。结果建议phyB察觉R断然调整叶绿素生合成，当phyA的角色能仅仅在phyB缺乏的异种被检测时。涉及叶绿素生合成的基因的表示层次的分析表明phytochromes由调整protochlorophylloxidoreductaseA(PORA)影响了叶绿素生合成表示。在叶绿体开发的phyB的角色也被分析，并且结果建议phyB察觉R由影响叶绿体和grana的数字调整叶绿体开发，以及叶绿体膜系统。
