Changes in Fructose 26-Bisphosphate Levels in Green Pepper (Capsicum annuum L.) Fruit in Response to Temperature

摘要

The regulatory metabolite, fructose 2,6-bisphosphate (Fru 2,6-P2) was found in green pepper (Capsicum annuum L.). The Fru 2,6-P2 level was found to: (a) rise rapidly in response to heat; (b) drop rapidly, followed by recovery, in response to cold storage of fruit and, (c) oscillate during cold storage of fruit. The possible existence of a relationship between chilling injury and Fru 2,6-P2 is considered.
