Outline of Final Research Achievements

Fruit ripening and senescence induced by ethylene and low-temperature exposure were investigated using next generation sequencer and Real-Time PCR in kiwifruit, popular and Satsuma mandarin. The low-temperature induced fruit ripening shared gene and their regulatory mechanism with ethylene induced ripening in part, however, there are several distinct differences between the two ripening regulation. Identification of transcription factors, NACs and FRFs, responsible for ripening and senescence by low-temperature and ethylene will play important role for new global understanding of physiology in fruit ripening and senescence.
