变度

The VVA0326- mutant carrying a deletion of the GGDEF domain displayed smaller colony morphology on LB plate while compared to the wild type. No difference in colony forming units was found indicating that growth rate is not likely a major factor to confer the phenotype of small colony. In addition, VVA0326- appeared to swim better than wild type bacteria on the swimming plate. VVA0326- grew better, while VVA0328- mutant, which carried a deletion of the EAL domain, grew worse than wild type when the bacteria were cultured on CAS plate at 30°C. This implied that changes in surface structures of the mutants affected the bacterial susceptibilities to HDTMA contained in CAS plate.

缺损了包含一个GGDEF功能区域的突变株 VVA0326-，培养在LB的洋菜胶上，呈现出较小的生长菌落，在测定单位菌落数的结果发现，VVA0326-在生长速度上，相较於野生株并没有不同，因此我们推论生长速率并不是造成菌落变小的主要因子，除此之外，VVA0326-在游泳的分析培养皿中游的比野生株快，在CAS的分析培养皿上，与野生株比较，VVA0326-有比较好的生长状态，而缺损了包含一个EAL功能区域的突变株VVA0328-，却有被抑制生长的现象，可能是因为突变株影响了表面的结构，进而改变了细菌对於HDTMA的敏感层度。
