Ethylene promotes fruit ripening, including softening. The fruit of melting-flesh peach (Prunus persica (L). Batsch) cultivar 'Akatsuki' produces increasing levels of ethylene, and the flesh firmness softens rapidly during the ripening stage. On the other hand, the fruit of stony hard peach cultivars 'Yumyeong', 'Odoroki', and 'Manami' does not soften and(More)
The fruit of melting-flesh peach (Prunus persica L. Batsch) cultivars produce high levels of ethylene caused by high expression of PpACS1 (an isogene of 1-aminocyclopropane-1-carboxylic acid synthase), resulting in rapid fruit softening at the late-ripening stage. In contrast, the fruit of stony hard peach cultivars do not soften and produce little ethylene(More)
Transgenic approach is an excellent way for the clarification of gene function, but it is generally difficult to create transgenic plants for most of the fruit trees including peach. Even if transgenic lines are successfully obtained, it will be extremely difficult to evaluate fruit traits due to the long juvenile phase of the plants. To overcome this(More)
A brown skin spot developed on the berries of Japanese grape cultivar Shine Muscat during storage at 0 °C for 3 months. The fungus isolated from these skin spots was identified as Cadophora luteo-olivacea based on the sequence of its ribosomal DNA internal transcribed spacer region. Morphological and culture characteristics corresponded to those reported(More)
