Transcriptome Profiling of Genes Involved in Ethylene-induced Fruit Abscission, Cloning and Characterization of Ethylene-regulated Genes in Citrus Sinensis
Abscission is an important determinant of citrus yield. Ethylene is a major abscission hormone that regulates many biological processes involved in abscission such as cell division, cell expansion and cell wall decomposition. The biosynthesis of ethylene has been elucidated. Previous researches indicated that two ethylene production systems, systemⅠandⅡ, exist in both citrus fruit and leaves. During the first phase (3~5d in mature leaves and 6~7d in young leaves, after detachment)systemⅠis operating....
