Environmental stress conditions cause extensive losses to agricultural production worldwide. Individually, stress conditions such as drought, salinity, heat, post-harvest senescence and microorganisms have been the subject of intense research. Though a great deal of knowledge has been advanced in the past 20 years, a large array of genes responsive to stresses in Arabidopsis is still unknown and unstudied. In this team project we would like to study the basic aspect of abiotic and biotic stresses related genes and proteins. Two projects deal with the dehydration stress (sub-projects 1 and 6), two with salt stress (sub-projects 2 and 6), two with heat stress (sub-projects 3 and 4), two with pathogen stress (sub-projects 8 and 9) and one each with senescence and light stress. We will use functional genomics, proteomics, structure bioinformatics, molecular genetics and physiological approach to study the specific gene function. The approaches used by all sub-projects are complementary. All the genes will be explored in this team project have some preliminary results and play regulatory role in stress responses. These includes upstream regulatory genes, like lectin receptor kinases (LecRKs), histone deacetylase 15 (HDA15), LSD1-like histone demethylase (LDLs); calcium binding protein, like OsCaM1-1; transcription factors like, AtDS1, Aintegumenta-Like 7 (AIL7), AtWRKY70, AtWRKY 54, and S1 class bZIP11, and other unknown function genes like, miRNAs, C3HC4-type RING E3 ligase (SlREL1), an RNase L inhibitor (SlRLI), a, neutral invertase (AtCINV1), drought inducible protein 19-2 (AtDi19-2). This will enhance coherence and cooperation among sub-projects for the common interest. While carrying out the research independently, in fact, developing strong interactions among sub-projects or laboratories working on a defined biological problem will strengthen our basic research and has a potential to contribute to agriculture improvement.阿拉伯芥轉錄子Aintegumenta-Like 7AtDS1乾旱誘導負向調控者Arabidopsis thalianaAintegumenta-Like 7AtDS1ERF/AP2 transcription factornegative regulator優勢重點領域拔尖計畫-總計畫:系統性分析模式植物在遭逢環境逆境上的重要調節基因或蛋白質
