十字花科作物根肿病的侵染生理与抗性遗传研究进展

摘要

Clubroot disease is caused by obligate biotrophic protist Plasmodiophora brassicae and is one of the most damaging for crucifer plants. Recently it has become a severe problem globally, especially in Europe, North America, East Asia and other regions. It is also threatening the normal vegetable supply in China in the near future. This review summarizes recent advances in the field of the physiological, biochemical and molecular basis of root gall formation, inheritance of clubroot resistance, molecular markers and its genetic maps in crucifer crops. Finally, future research direction of clubroot resistance are proposed.%十字花科植物根肿病是由芸薹根肿菌侵染而引起的危害最大的病害之一,近年来,该病在世界范围尤其是在欧洲、北美、东亚等地区日趋严重,我国很多地区的十字花科作物也正面临着根肿病的严重威胁.本文就芸薹根肿菌侵染过程中寄主植物的生理生化变化及其分子基础、根肿病抗性遗传规律和分子标记与遗传图谱等多方面的研究进展做一概述,并对该领域今后的研究进行了展望.
