Suppressors of systemin signaling identify genes in the tomato wound response pathway.

Genetics - 1 Nov 1999

Howe G A, Ryan C A

Abstract excerpt

In tomato plants, systemic induction of defense genes in response to herbivory or mechanical wounding is regulated by an 18-amino-acid peptide signal called systemin. Transgenic plants that overexpress prosystemin, the systemin precursor, from a 35S::prosystemin (35S::prosys) transgene exhibit constitutive expression of wound-inducible defense proteins including proteinase inhibitors and polyphenol oxidase. To...
