The research team led by Professor Wang Zhiqiang from the Zhengzhou Fruit Research Institute of Chinese Academy of Agricultural Sciences (CAAS) has been working on the study of Peach fruit quality biology for many years. The team made important progress in the molecular mechanism of ethylene and abscisic acid synergistically regulating fruit ripening and softening. Peach cultivars are classified as melting flesh (MF) or non-melting flesh based on their fruit firmness and texture. Generally speaking, Ethylene is essential for the ripening of climacteric fruits;and ABA played an important role in non-climacteric fruits ripening process. Peach are climacteric fruits and exhibit a marked increa...
