摘    要:研究了转PSAG12-ipt基因水稻和对照植株发育过程中叶片中的叶绿体结构的变化。发现水稻发育到乳熟期,转基因植株叶片中的叶绿体与对照植株开始出现明显的差别。对照叶绿体中嗜锇体体积增大,数目增多,大部分基粒的类囊体膜膨胀、裂解,片层结构解体。而转基因植株叶片中的叶绿体结构变化不大,嗜锇体相对有所增加,但体积较小,大部分基粒类囊体片层结构仍然排列整齐,少数类囊体垛叠化丧失。

关 键 词:P_(SAG12-ipt)基因  叶绿体  超微结构

Abstract:The structure of chloroplast was investigated during its development in transgenic rice(P_(SAG12-ipt))and control. The results revealed that there was an obvious differentiation of chloroplasts between transgenic rice and control during milky ripe stage. In control,the size and number of osmiophilic granules increased greatly and the thylakoid membrane of most grana swelled and split and most grana lamellae disappeared. Whereas in transgenic rice,only the number of osmiophilic granules increased and most grana-thylakoid lamellae arranged in order.
Keywords:P_(SAG12-ipt) gene  chloroplast  ultrastructure
