Pollination-Induced Expression of Ethylene Biosynthetic Genes at Transcription Level in Orchid Flowers

Abstract

Abstract: The authors investigated pollination-induced ethylene production and expression patterns of genes encoding 1-aminocyclopropane-l-carboxylate (ACC) synthase and ACC oxidase in orchid flowers (Doritaenopsis hybrida Hort. ). Following pollination both ACC synthase and ACC oxidase mRNAs were detected in the different organs of flowers, and the patterns of both ACC synthase and ACC oxidase mRNA accumulation were similar, mRNA accumulation of ACC synthase mRNA was more organ-specific than that of ACC oxidase mRNA. However, ACC oxidase mRNAs were much more abundant than ACC synthase mRNAs in the flower organs.

Key words: Pollination, Ethylene, ACC synthase, ACC oxidase, mRNA, Doritaenopsis hybrida
