Outline of Final Research Achievements

European pear fruit can’t ripen on the tree. They are harvested at the mature green stage and ripened off the tree. A tree factor that inhibits ripening has been postulated to explain this effect. However, until now, nobody has elucidated its identity. Here, we have investigated the profiles of metabolic substances induced by girdling the fruit peduncle to inhibit phloem transport of the tree factor. And we have searched genes related to tree factor’s effect in European pear by RNA-seq analysis. Total 24 substances showed differences between fruit without girdling and with girdling by metabolome analysis. Also, up-regulated 9 genes and down-regulated 34 genes by girdling treatment were identified by RNA-seq analysis.
