Conteúdo: | Ethylene is involved in fruit rippening, wounding responses and other stress responses. 1-aminocyclopropane-1-carboxylate (ACC oxidase) catalyses the last reaction of ethylene biosynthesis and is a key enzyme in the pathway. Many ACC oxidase genes have been characterized in other plant systems. During the post-harvest physiological deterioration (PPD) of the cassava tuber ethylene production increased after a lag of 6 to 16 hours. The role of ethylene in the development of PPD is not clear, though there are some indications that ethylene is not directly involved in the process. To further understand the role of ethylene in the development of PPD, an ACC oxidase cDNA was isolated from a PPD-related cDNA library using tomato ACC oxidase cDNA as probe.
