Cell Surfaces in Plant-Microorganism Interactions

Abstract
Nine wild tomato species were surveyed for variability in ripening characteristics. External signs of ripening, age of fruit at ripening, and ethylene production patterns were compared. Ethylene production was monitored using an ethylene-free air stream system and gas chromatography. Based on these ripening characteristics, the fruits fell into three general categories: those that change color when they ripen, green-fruited species that abscise prior to ripening, and green-fruited species that ripen on the vine.
