Resistance to root-knot nematode Meloidogyne incognita in transgenic tobacco lines expressing AtNPR1 (a) Shoot weight and (b) Root weight after six weeks of inoculation with nematodes. Transgenic plants show enhanced resistance to the nematode in all the parameters studied. The difference in means between the wild type and the transgenic lines was verified by Student's t- test and found to be significant at 5% level. Similar growth patterns in the unchallenged wild type and transformed plants were observed.
