Summary Introduction
To write:
About the method of transmission of Pectobacterium carotovorum.
Introduction:
Pectobacterium carotovorum is a bacterium that infects plant species and belongs to the family Pectobacteriaceae. It synthesizes the pectolytic enzyme that is capable of hydrolyzing a compound pectin present between two plant cells. This results in a disease called bacterial soft rot.
