Identify physiological/biochemical mechanisms that control potato tuber dormancy/sprout growth and wound-healing/skin set. Determine the roles of endogenous hormones in tuber dormancy progression and identify the biochemical mechanisms governing hormone homeostasis in tubers as related to dormancy. Identify and characterize genes controlling tuber dormancy/sprout growth and wound-healing/skin set. Identify hormones and endogenous elicitor systems initiating and regulating wound-healing in harvest-damaged and cut-seed tubers. Determine biochemical changes in tuber periderm cell wall conferring resistance to excoriation (skinning during maturation.) Project has been classified as "Exempt" by the rating Institutional Biosafety Committee, ltr dated 6-12-02.
