Abstract

Research Note

Ferredoxin glutamate synthase (ferredoxin glutamine: oxoglutarate aminotransferase, or Fd-GOGAT, EC 1.4.7.1) activity was detected in grapevine (Vitis vinifera L.). Highest Fd-GOGAT activity was found in lamina tissue. Moderate levels of activity were found in petiole, tendril, rachis, and flower tissues. No activity was detected in extracts from pedicel tissue. Western blotting with rice Fd-GOGAT antibodies resulted in a positive reaction with single grape protein band of 73 kDa in all tissue types tested.
