Abstract:	為瞭解植物耐受高溫逆境之機轉，進而以遺傳工程改良作物耐熱力以因應全球暖化之威脅，本實驗室以前向式遺傳學的策略，自ethyl methanesulfonate (EMS)處理過之阿拉伯芥M2子代中，篩選出一對高溫逆境失去耐受性之突變植株，命名為heat-intolerant 4 (hit4)。進一步的生理實驗發現，hit4雖失去先天性熱耐受能力(basal thermotolerance)，卻仍保有後天性熱耐受能力(acquired thermotolerance)。經基因定位、互補實驗及序列比對，確認hi;The Arabidopsis mutant heat-intolerant 4 (hit4) was isolated from an ethyl methanesulfonate-mutagenized M2 population on the basis of its inability to withstand prolonged heat stress (four days at 37°C). Further characterization indicated that hit4 was im;研究期間：10408~10507
