研究概述
Research Description
我们实验室研究兴趣主要集中在两个领域：其中一个领域主要是研究光调控的拟南芥幼苗发育过程的分子和生化机制。我们实验室在研究参与光调控的拟南芥发育过程的遗传通路时，找到了12个多效性COP/DET/FUS位点，确定它们介导了光对拟南芥幼苗发育过程的调节。其中，COP1是拟南芥光形态建成的关键的抑制因子，暗中在细胞核内作为E3通过26S蛋白体降解促进光形态建成的转录因子，而在光下COP1活性被抑制且在核内的丰度降低；另外一个基因COP10编码一个类似E2的蛋白；其余的多数基因编码一个高度保守的多亚基蛋白COP9复合体（COP9 signalosome）的不同亚基，COP9复合体是一个新的E3连接酶的调节因子，可以促进NEDD8/RUB1从特定的E3连接酶上解离下来。COP9复合体是细胞对外界刺激或胁迫产生反应的新的调节成分。目前，本实验室正在通过分子遗传和基因组学的方法，进一步深入地研究这类在所有多细胞有机体中保守的细胞调节复合体的功能。
我们实验室另外一个研究领域是在水稻中从基因组水平探讨DNA甲基化和chromatin的修饰和结构，我们已经建立了一系列的实验技术平台，包括全基因组表达芯片，高密度寡核苷酸tilling芯片，以及ChIP-chip分析方法，可用于研究全基因组水平的基因表达以及DNA和组蛋白修饰的模式，我们的目的是寻找水稻的栽培过程和杂种优势形成的分子及遗传基础。
My research at NIBS is focused on two areas. One is the molecular and biochemical basis for light control of Arabidopsis development. Our studies have revealed a dozen pleiotropic COP/DET/FUS loci responsible for mediating light control of seedling development. These include COP1, which functions as the master repressor of photomorphogenic development and acts within the nucleus as an E3 ligase by directly targeting photomorphogenesis-promoting transcription factors for degradation by the 26S proteasome in darkness. Light inactivates COP1 and causes a reduction in its nuclear abundance. Another gene, COP10, encodes a probable E2 component. Most remaining genes encode subunits of a highly conserved multi-subunit protein complex, the COP9 signalosome, a novel regulator of the E3 ligases that promotes de-conjugation of NEDD8/RUB1 from certain E3 ligases. This group of regulatory proteins enables the cell to respond to external stimuli or stresses. Currently, we are applying both molecular genetic and genomic approaches to further analyze the components of this novel cellular machinery, which is conserved among all multicellular organisms. Our second area of research is the genome-wide organization of DNA elements and chromatin in rice. We have constructed a series of technology platforms, including a whole genome expression microarray, a high density oligomer tiling microarray, and a ChIP-chip assay, to define genome wide gene expression profiles as well as DNA and histone modification patterns. Our goal here is to search for the genomic basis for rice domestication and heterosis.
