Integrated Analysis of Grapevine Wounding Responses
Grapevines are continually wounded throughout cultivation, particularly during winter pruning. To limit pathogen infection and tissue dehydration, plants have evolved a wide range of wound responses that protect damaged tissues. These responses include changes in gene expression and the synthesis of protective compounds such as polyphenols. In addition to these molecular responses, plants occlude damaged xylem vessels following wounding and pathogen infection, forming structures such as gels, gums, and tyloses.
