目的基因 Bait gene 筛选基因 Prey gene 功能注释 Annotation RIP4/PHOT1 蓝光受体PHOT1, 可调节强弱蓝光诱导的下胚轴向光反应, 调节弱光诱导的叶绿体聚光运动、向光性。 Blue light photoreceptor. Mediates blue light-induced phototropism, chloroplast accumulation, stomatal opening, and leaf flattening. RIP2/KIX8 编码KIX8蛋白, 与PPD2相互作用, 调节植物拟分生组织分裂, 调控植物叶片大小发育。 Encodes KIX8. Interacts with PPD2. Regulates meristem division and leaf size. RIP1 功能未知。Unknown protein. RPT2 RIP3 功能未知。Unknown protein. RIP6 核蛋白, 功能未知。Hypothetical nuclear protein. RIP5/JAC1 JAC1蛋白, 定位在细胞质及叶绿体中, 参与叶绿体聚光运动但不参与叶绿体避光运动, 同时响应蓝光诱导。 Located in the chloroplast and cytoplasm. Involved in chloroplast accumulation, chloroplast avoidance movement, and cellular response to blue light.
