Pepper Gene Confers Nematode Resistance in Tomato
July 20, 2007| |
A root-knot nematode resistance gene from hot pepper (Capsium annuum) called CaMi was found to confer nematode resistance in tomato, the first time that a nematode resistance gene has been introduced in the crop species.
The resistance gene CaMi was isolated from pepper line ‘PR 205’ and its function was confirmed by introducing it into root-knot nematode susceptible tomato plants using Agrobacterium tumefaciens-mediated transformation. Over-expression of the gene conferred durable resistance to root-knot nematodes. The Chinese researchers reported that in the transgenic tomato plants, there have been either no or only a few egg-masses on the roots after nematode infection.
Root-knot nematode is one of the major pests of pepper worldwide. Infected plants show symptoms of galls or root knots. These root structures severely affect the water and nutrient uptake in infected plants and may cause yield reduction, stunting and wilting in the crop.
