Abstract

Two highly homologous flagellin genes, flaA and flaB, are expressed in Bacillus thuringiensis subsp. alesti. Both genes were found to be transcribed during vegetative growth. After the onset of sporulation, transcripts could not be detected. Both flaA and flaB were found to be transcribed from sigma70-like promoters. In addition, the 3'-terminal half of flaA was cloned and sequenced, completing the sequence of flaA.

摘要

在苏云金芽孢杆菌以色列亚种中表达了两个高度同源的鞭毛蛋白基因，flaA 和 flaB。发现这两个基因在营养生长期间都进行转录。在芽孢形成开始后，无法检测到转录本。发现 flaA 和 flaB 均从类似 sigma70 的启动子转录。此外，克隆并测序了 flaA 的 3' 末端一半，完成了 flaA 的序列。
