Abstract
We screened for transposon-generated mutants of Synechocystis sp. strain PCC 6803 that exhibited aberrant phototactic movement. Of the 300 mutants generated, about 50 have been partially characterized; several contained transposons in genes encoding chemotaxis-related proteins, while others mapped to novel genes. These novel genes and their possible roles in motility are discussed.
摘要
我们筛选了集胞藻6803株系中转座子产生的突变体，这些突变体表现出异常的趋光运动。在产生的300个突变体中，约50个已得到部分表征；其中一些在编码趋化相关蛋白的基因中含有转座子，而其他一些则定位到新基因上。本文讨论了这些新基因及其在运动性方面可能发挥的作用。
