Root - lesion nematodes
Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals occur worldwide in all environments. Most species are beneficial to agriculture. They make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. Pla...
متن کاملResponses of Strawberry Species and Cultivars to the Root-lesion and Northern Root-knot Nematodes
The relative susceptibility of 44 genotypes of wild Fragaria L. and commercial cultivars of strawberry Fragaria ×ananassa Duch. to Meloidogyne hapla Chitwood and Pratylenchus penetrans (Cobb) Filipjev & Shuurmans Stekhoven was evaluated in the greenhouse. Eleven genotypes were highly resistant to populations of M. hapla from Washington State and Oregon, with Rf values (initial nematode density/...
متن کاملPhenol accumulation related to resistance in tomato to infection by root-knot and lesion nematodes.
Host-parasite relationships of Meloidogyne incognita acrita and Pratylenchus penetrans were compared on three closely related cultivars of tomato: 'Nemared', resistant to root-knot nematodes; 'Hawaii 7153', moderately resistant; and 'B-5', susceptible. Root-knot nematode larvae induced typical galls on the roots of B-5; larvae that entered Nemared were walled-off by necrotic cells; both reactio...
متن کاملMicrobiomes associated with infective stages of root-knot and lesion nematodes in soil
Endoparasitic root-knot (Meloidogyne spp.) and lesion (Pratylenchus spp.) nematodes cause considerable damage in agriculture. Before they invade roots to complete their life cycle, soil microbes can attach to their cuticle or surface coat and antagonize the nematode directly or by induction of host plant defenses. We investigated whether the nematode-associated microbiome in soil differs betwee...
