Outline of Final Research Achievements

We investigated the degree of parthenocarpy of four citrus cultivars, Satsuma mandarin, Kiyomi, Hyuganatsu, and clementine. Especially, Satsuma mandarin had higher rate of development of ovaries at the early stage besides strong parthenocarpy. Microarray analysis suggested that there was difference in gene expression of gibberellin (GA)-biosynthetic pathway genes between parthenocarpy and non-parthenocarpy cultivars. Therefore, GA 20-, GA 2-, and GA 3-oxidase genes of Satsuma mandarin were isolated and subjected to functional analysis, resulting in the identification of enzymatic genes that have an activity of growth promotion or retardation.
