摘要:

大部分兰科石斛属植物都具有极高的药用和观赏价值。全球大约有1 200~1 500种石斛属植物,在我国分布的有76种,主要分布在西南、华南和台湾等地,其中云南最多,有62个种。花香是观赏植物重要的品质性状,随着分子生物学发展,在花香物质的生物合成途径、相关基因调节机制和基因工程方面等取得了较大进展,对近年来报道的石斛属26种植物中17种主要赋香成分和植物花香的生物合成途径、相关酶与基因调节机制的研究成果进行了综述,并对今后的研究和发展方向等进行了展望,旨在为今后植物花香性状的改良提供参考。

Abstract:

Most Dendrobium species in the Orchid family have high medicinal and ornamental value. There are about 1 200~1 500 species of Dendrobium in the world, among which 76 species of Dendrobium are distributed in China, mainly in Southwest, South and Taiwan, and Yunnan is the most distribution with 62 species. Floral scent is important ornamental trait of ornamental plants. With the development of molecular biology, great progress has been made in biochemical synthesis pathways, related gene regulation mechanisms and genetic engineering of floral scents. 17 major odorant components and the biosynthetic pathways, related enzymes and gene regulation mechanisms of 26 Dendrobium species reported in recent years were reviewed, and the future research and development direction were prospected, so as to provide reference for the improvement of floral scents in the future.

Key words: floral scent, Dendrobium, volatile constituent, terpene, terpene synthase
