Research Abstract |
Tomatoes and melons are classified as climacteric fruits, whose ripening was regulated by ethylene. A mutant melon cultivar 'Honey dew' cannot synthesize ethylene at ripening stage and then be stored with a long storage life. Based on characterization of the mutation of 'Honey dew', I tried to identify the transcriptional regulator for ethylene synthesize genes and elucidate the mechanism for ethylene signaling and transcription. Then, 2 type genes were cloned as candidate genes. To date, the preliminary experiments, gene silencing and expression manipulation, suggested a possibility that that they and their homologues might repress fruits ripening.
