Abstract

Bean leaf tumors induced by Agrobacterium tumefaciens strain 181 show enhanced growth in response to octopine or lysopine only if one of these compounds is present during the period of tumor induction. Either compound applied during this period results in tumors which subsequently respond to both. The combined action of the bacterium plus octopine or lysopine at induction is proposed to induce transcription of plant genes coding for enzymes involved in the degradation and/or biosynthesis of octopine and lysopine.

摘要

根瘤诱导的豆叶瘤仅在诱导期存在一种化合物(即:黄瓜碱或六氢吡啶羧酸)时,才会对该化合物表现出增强的生长反应。在该时期内施用任一种化合物,都会导致随后对二者均有反应的肿瘤。提出的诱导过程中细菌与黄瓜碱或六氢吡啶羧酸的联合作用,可诱导参与降解和/或生物合成黄瓜碱和六氢吡啶羧酸的植物基因的转录。
