Other claims from this paper (8)

Observation The hrpE mutant did not interact with rice cells.
Intervention effect The mutant grew less in rice tissues than wild-type bacteria.
Mechanism Loss of Hrp pilus formation in rice parenchyma explained the mutant’s loss of pathogenicity.
Intervention effect Complementing hrpE restored rice pathogenicity.
Intervention effect Complementing hrpE restored Hrp pilus formation between bacterial and rice cells.
Intervention effect The hrpE mutant lost ability to trigger hypersensitive response in tobacco.
Intervention effect Complementing hrpE restored hypersensitive response induction in tobacco.
Mechanism The authors infer that hrpE is essential for Hrp pilus formation and effector secretion into rice cells.
