Identification and functional characterization of the distinct plant pectin esterases PAE8 and PAE9 and their deletion mutants.

abstract：:In spite of their silent and sessile life, plants are dynamic organisms that have developed advanced defence strategies in their adaptation to the pressure of herbivores and pathogens. Natural plant products play an important role as chemical weapons in this warfare. Characteristic of cruciferous plants is the synthes...
