Abstract

The production of pectin lyase (Pnl) and carotovoricin (Ctv), as well as cell lysis in the plant-pathogenic bacterium Erwinia carotovora subsp. carotovora Er are induced by mitomycin C. Here, Pnl and Ctv production and cell lysis were found to be temperature-dependent. The optimal temperature for Pnl production was 30°C. However, the optimal temperature for both Ctv production and cell lysis was 23°C, at which Pnl production was reduced to 47% of the maximum. These data suggest the possible existence of novel regulation system(s) for the production of Pnl and Ctv, and cell lysis, in addition to the well-documented regulation system of recA, rdgA, and rdgB genes.
