Xanthomonas biofilm biomass

Sheet 1: The rsmA mutant also has increased biofilm and cell adhesion on a glass surface when assessed by crystal violet staining. Sheet 2: A triple disruption of XC_1803/XC_2715/XC_2866 in an rsmA mutant background leads to reduction in biofilm to a level similar to that of the wild-type strain. In contrast mutation of XC_1803, XC_2715 and XC_2866 alone or in pairwise combination has little or no effect on biofilm formation in the rsmA mutant.

工作表1：经结晶紫染色检测证实，rsmA突变体在玻璃表面的生物膜形成能力与细胞黏附活性均显著增强。
工作表2：在rsmA突变体的遗传背景下，对XC_1803、XC_2715、XC_2866实施三重基因敲除后，菌株的生物膜形成能力降至与野生型菌株相近的水平。与之相反，单独敲除或两两组合敲除XC_1803、XC_2715、XC_2866，对rsmA突变体的生物膜形成几乎无显著影响。
