林辰涛教授为植物光信号传导及蓝光受体研究领域的国际权威。其在该领域做出的主要成果包括:首次发现了植物蓝光受体隐花素(CRY1)的色素团化学成分;第2种隐花素CRY2以及在调控光周期开花中的作用;钙离子结合蛋白在光信号协同调节中的地位;隐花素磷酸化以及在光信号传递中的功能;隐花素信号传递的光诱导蛋白相互作用假设以及作为其直接证据的第一个植物CRY特异的信号传递转录因子基因CIB1的功能与作用机制;及大豆蓝光受体CRY1在控制大豆成熟期以及纬度分布上的作用。主持人实验室为受到美国国家卫生研究院(NIH)连续资助十多年的为数不多的植物科学实验室之一,其在Science、Nature、PNAS和Plant cell等刊物上发表50多篇研究论文。主持人于2003年开始在中国农科院开展农作物基因功能的合作研究。并于2009年成为中国农科院高层次人才(千人计划)入选者。

研究方向与主要研究内容:

水稻功能基因组学。主要采用显性变异基因组学与蛋白组学等方法研究水稻转录调节机理,以及其在水稻产量、氮肥利用率及抗逆性等重要农艺性状中的作用与功能。
