摘要:

园艺植物富含类胡萝卜素,提高类胡萝卜素含量是园艺作物育种目标之一。概述了近年来在高等植物中类胡萝卜素的合成、氧化裂解和其它衍生代谢途径的研究进展,并在结构基因调控、转录因子调控、转录后调控和库源调控等多个层面上阐述了类胡萝卜素生物合成调控机制。其中,调控类胡萝卜素合成的转录因子已经成为近年来研究的热点,主要分为直接调控类胡萝卜素合成和影响果实成熟进而间接调控类胡萝卜素合成两大类。随着研究的不断深入,新转录因子、新基因和新调控方式正不断被挖掘。

Abstract:

Carotenoids are the most prevalent natural products. Horticultural crops are principal dietary sources of carotenoids,thus,the innovation of new germplasm packed with carotenoids becomes one of the long term focus for breeding goals. In this review,recent progress on precursor,linear carotenoids,cyclic carotenoids biosynthesis and other metabolism pathways were reviewed. Furthermore,the modulations of carotenoid production were divided into three levels:The direct regulation on structural genes in the biosynthetic pathway;The regulation through effects of transcription factors;The post- transcriptional control and the source-sink regulation. The transcription factors that directly involved in carotenoid biosynthesis and ripening process related but indirectly altered carotenoids profiles were also reviewed. It is believed that more new genes,transcription factors or modulations was to be discovered in the near future.

Key words: horticultural crop, carotenoid biosynthesis, regulation, transcription factors
