Alternative sigma factor RpoN and its modulation protein YhbH are indispensable for Erwinia amylovora virulence.

Molecular plant pathology - 1 Jan 2014

Ancona Veronica, Li Wenting, Zhao Youfu

Abstract excerpt

In Erwinia amylovora, ECF (extracytoplasmic functions) alternative sigma factor HrpL regulates the transcription of hrp (hypersensitive response and pathogenicity)-type III secretion system (T3SS) genes by binding to a consensus sequence known as the hrp box in hrp gene promoters. In turn, the expression of hrpL has been proposed to be positively controlled by alternative sigma factor 54 (σ(54)) (RpoN) and HrpS,...
