I. Summary
SecReT6 ID26 experimental
StrainRalstonia solanacearum GMI1000
Repliconplasmid pGMI1000MP [Browse all T6SS(s) in this replicon]
CommentTssB of R. solanacearum was required for secretion of Hcp, the hemolysin coregulated protein and a hallmark of T6S pathway. Deletion of tssB in R. solanacearum GMI1000 strain resulted in defect of biofilm formation, and the expression of the flagella operon is decreased, leading to decreased motility. More importantly, tssB mutant strain had significantly attenuated its virulence on tomato plants.
Functionanti-eukaryotic; effector translocation
