优异抗源欧洲山芥的研究与利用进展

Advances on Research and Utilization of Elite Resistant Resource–Barbarea vulgaris

欧洲山芥(Barbarea vulgaris R.Br.)是一种能合成皂苷的二年生十字花科植物,被认为是研究皂苷生物合成、植物与昆虫协同进化的理想模式植物。综述了欧洲山芥形态及生物学特性、起源演化、抗虫相关次生代谢、营养条件及环境对抗虫性的影响、作为"诱杀作物"的优越性、抗虫基因定位等研究进展,并对存在的问题和发展方向进行了讨论,以期为充分利用该优异种质资源进行十字花科作物抗病抗虫遗传育种研究和进行重要流行病虫害的综合防治提供参考。

Barbarea vulgaris is a biennial crucifer which can synthesize and accumulate saponins. It is an ideal model species for studying saponin biosynthesis,insect resistance and plant-insect co-evolution. In this paper,the research advances on B. vulgaris about the morphological and biological characteristics,evolution,insect-resistant related secondary metabolisms,effects of nutrition and environment on its insect resistance,the advantages as dead-end trap crops,gene mapping of insect-resistance genes were presented. The existing problems and the research orientation in the future were discussed. This review will provide the valuable information for the effective use of this wild species in pest management and genetic improvement of cruciferous crops.
