| Abstract/Description: | A pot culture experiment was conducted to understand the biochemical and molecular changes associated with resistance reaction of banana against root-lesion and root-knot nematodes on five varieties of banana viz., Nendran (AAB), Robusta (AAA), Pisang Jari Buaya (AA), Karthobiumtham (ABB) and Musa balbisiana (BBB). The highest protein concentration and increased peroxidase activity was observed in cvs.Nendran and Robusta whereas minimum was observed in cvs.Musa balbisiana, Karthobiumtham and Pisang Jari Buaya. The activity of polyphenol oxidase was reduced in infected plants of cvs.Nendran and Robusta. But, the activity increased in cvs.Pisang Jari Buaya and Musa balbisiana. The phenylalanine ammonia lyase (PAL) activity was significantly lower in cvs.Nendran and Robusta compared to other three varieties. The phenolic accumulation was increased by 56% in cv.Nendran after nematode infection whereas there was only 2% increase in Karthobiumtham. The molecular analysis indicated a higher rate of mRNA synthesis soon after nematode infection. |
| Description: | The root-lesion (Pratylenchus coffeae) and rootknot nematodes (Meloidogyne incognita) are considered to be an important nematode pests of banana causing extensive crop damage (Reddy et al., 1989; Jonathan & Rajendran, 2000 and Sundararaju & Cannayane, 2003). One of the most economical and effective ways to control plant parasitic nematodes is exploiting resistant / tolerant cultivars of banana. Resistance is an incompatible reaction of plants towards nematode infestation. Narayana & Reddy (1980) correlated the levels of phenols in roots with resistance in tomato cultivars against root-knot nematode M.incognita. Hence, the present investigation was undertaken to study the biochemical and molecular changes in nematode resistant and susceptible cultivars of banana infested with P.coffeae and M.incognita. |
