LonB mutant

ABSTRACT: The bacterial Lon protease participates in a variety of biological processes. In Pseudomonas syringae, mutation of lon is known to activate hrpL and a few hrpL-regulated genes in the rich medium. The elevated expression of hrpL and hrpL-regulated genes results from of increased stability of HrpR, the transcriptional activator of hrpL, in the lon mutant. Here we conducted a microarray analysis to determine genes that are differently expressed in the lon- mutant of P. s. pv. tomato DC3000 grown in the rich medium KB. Most genes induced in the lon- mutant belong to the HrpL-regulon or are related to the transcription, protein synthesis, and energy metabolism. The major group of genes reduced in the lon- mutant is related to cell wall biogenesis. The HrpL-regulated genes exhibit different indu
