Following in vitro infection with Agrobacterium rhizogenes wild strain (mannopine, 8196) and two A. tumefaciens transconjugant strains (C58C1 pArA4abc and C58C1 pArA4b) transformed (hairy) roots were induced in pumpkin (C. pepo L.) cotyledons. The presence of pRi T-DNA in pumpkin long-term hairy root cultures was determined by Southern hybridization. The influence of plant growth regulators on ...

Interactions between root-knot nematodes and viruses were recently reviewed by Taylor (4). Compared to virus-free cowpea (vigna sinensis Endl.), cowpea mosaic virus-infected plants formed fewer galls on roots in response to infection by Meloidogyne incognita (Kofoid and White) Chitwood (2). On the other hand, tobacco plants (Nicotiana tabacum L.) infected with tobacco ringspot virus (TRSV) and ...
