A Critical Appraisal of DNA Transfer from Plants to Parasitic Cyst Nematodes.

ABSTRACT: Plant-parasitic nematodes are one of the most economically important pests of crops. It is widely accepted that horizontal gene transfer-the natural acquisition of foreign genes in parasitic nematodes-contributes to parasitism. However, an apparent paradox has emerged from horizontal gene transfer analyses: On the one hand, distantly related organisms with very dissimilar genetic structures (i.e. bacteria), and only transient interactions with nematodes as far as we know, dominate the list of putative donors, while on the other hand, considerably more closely related organisms (i.e. the host plant), with similar genetic structure (i.e. introns) and documented long-term associations with nematodes, are rare among the list of putative donors. Given that these nematodes ingest cytoplasm from
