【摘要】：番茄是重要的栽培蔬菜,在世界各地被大面积种植。根结线虫侵染番茄根部对寄主产生损伤,使植株黄化、矮化、下部叶片脱落、成熟期果实小。同时,常见的土传病害,如黄萎病(Cyanosis)、枯萎病、青枯病(Ralstonia solanacearum)等往往会在遭受线虫侵染后爆发。根结线虫病会严重影响番茄产量,甚至导致绝产。Mi-1做为目前唯一被转育到栽培品种中的番茄抗根结线虫基因,在番茄栽培中起着重要的作用。本研究通过对Mi-1基因结构功能分析,Mi-1基因对根结线虫抗性机理,分子标记与抗根结线虫育种应用等方面的研究进展加以综述,意在总结前人相关研究进展并对其存在的问题及今后发展方向进行展望。
[Abstract]:Tomato is an important cultivated vegetable, which is planted in large area all over the world. Root knot nematode infecting tomato root cause damage to the host, making plants yellow, dwarfing, falling leaves and small fruits at maturity. At the same time, common soil borne diseases, such as Verticillium Wilt (Cyanosis), wilt wilt disease (Ralstonia solanacearum) and so on, often suffer from the line. The root knot nematode will seriously affect the yield of tomato, and even lead to.Mi-1 as the only tomato resistant to root knot nematode gene, which plays an important role in tomato cultivation. In this study, the structure function analysis of Mi-1 gene, the mechanism of Mi-1 gene resistance to root knot nematode, molecular marker The research progress on the breeding and application of root knot nematode resistance is reviewed, which is intended to sum up the progress of previous studies and to look forward to its existing problems and future development direction.
