Phytotoxic Effects and Phytoalexin-Elicitor Activity of Microbial Pectic Enzymes
Microbial pectic enzymes not only macerate plant tissue but also kill plant cells and elicit synthesis and accumulation of phytoalexins (Hahn et al., 1988). We have evidence suggesting that these three physiological activities of pectic enzymes may be regulated by factors such as endo-polygalacturonase inhibiting proteins (PGIP) and pH.
