本论文根据已建立的高等植物豌豆光合作用中心D1蛋白模型结构和前期工作经验，运用生物合理设计方法，对其中抑制希尔反应活性最好的一类化合物—氰基丙烯酸酯类除草剂的若干侧链进行修饰，以期得到抑制活性较好的化合物。

The main results are as following:(1) Arabidopsis in planta transformation were made by Agrobacterium tumefaciens carrying the activation tagging vector pSKI015 with herbicide-resistant Bar gene as a selective marker. About 12 000 independent transformant lines were acquired by the above method, from which two mutants related to plant defense response and development, asr1 (auxin and .salicylic acid responsive 1.) and dai1 (brought tolerant and obscisic acid insensitive 1) were isolated.

本文以拟南芥为实验材料，以激发标签为技术平台，构建了拟南芥的功能获得突变体库，从中筛选具有抗病、抗逆表型的突变体，克隆基因并进行基因的功能研究，取得的主要结果如下：(1)利用含激发标签质粒pSK1015的农杆菌直接转化拟南芥植株，以抗除草剂的Bar基因为筛选标记，获得了约有12000个独立转化株系的突变体库，并从中筛选到2个与抗病、抗逆和发育相关的突变体asr1(auxin and salicylic acid responsive 1)和dai1(drought tolerant and abscisic acid insensitive 1)。
