MI00244.cl, for example, had homology to 47 ESTs in our collection from other Tylenchida species including root-knot nematodes M. javanica, M. hapla and M. arenaria , cyst nematodes H. glycines and G. rostochiensis , and the lesion nematode Pratylenchus penetrans with E-values from 7e-78 to 3e-05.
First, root-knot nematodes and rhizobia occupy similar niches in the soil and in roots, and thus the opportunity for HGT may be omnipresent.
The generation of expressed sequence tags (ESTs) by single-pass random sequencing of cDNA libraries is a powerful tool for rapid gene transcript identification in metazoans [ 14 15 16 17 ] including parasitic nematodes of humans and animals [ 18 19 20 21 22 23 ] . High-throughput projects on two dozen nematode species have now brought the total number of publicly available roundworm ESTs to nearly 400,000, with half the sequences coming from parasites [ 24 25 26 27 ] . As a part of these efforts, EST sequencing from plant parasitic nematodes is in progress [ 28 ] and pilot EST datasets from the root-knot nematode M. incognita and the cyst nematodes Globodera rostochiensis and G. pallida second-stage larvae have recently been analyzed [ 29 30 ] .
It is possible that root-knot nematodes have adapted a portion of Nod factor biology to the induction of feeding sites, rather than nodules, in plants.
A possible ancient bacterial origin of these genes has been theorized [ 17 18 19 ] . A bacterial origin for a number of root-knot nematode (RKN) genes also has been proposed, although their possible role in parasitism is less clear.
