Nematodes are ubiquitous animals even the most barren habitats such as the deep-sea abyssal plains support 105 individuals per square meter whereas productive habitats such as agricultural fields support up to 108 nematodes per square meter. Although most research on nematodes is focused on the free-living model Caenorhabditis elegans and species important as human or veterinary parasites the Society of Nematologists SON largely represents scientists interested in the other species. Two speakers in the plenary session Diana Wall Colorado State University Fort Collins USA and Byron Adams Brigham Young University Provo USA gently chided the SON membership for not embracing contemporary biology more broadly - with the question have we taken our blinders off - somewhat ironically given the recent inroads genomic approaches have made towards the understanding of nematode phylogenies evolution and function. The tight integration of genomics with cell biology was especially evident in a symposium on plant-nematode interactions chaired by Kris Lambert University of Illinois Urbana USA . Lambert s earlier work identified a chorismate mutase gene in the plant-parasitic root-knot nematode and postulated that this had been acquired from a bacterial donor via a horizontal gene transfer HGT event. Although the function of this enzyme in the host-parasite interaction remains speculative Lambert s demonstration at the meeting of multiple forms of the protein does argue for a genuine role .
