The northern Root-Knot-Nematode ''Meloidogyne hapla'' is a sedentary endoparasite, and only second-stage juveniles (the infective stage) and adult males (which may be rare) are present in soil. They are a major "disease" affecting many food crops worldwide causing an estimate damage of US$ 100 billion.<br />

excerpt from "Sequence and genetic map of Meloidogyne hapla: A compact nematode genome for plant parasitism.", Opperman et al.<br />
<br />
Many isolates of ''M. hapla'' reproduce by facultative meiotic parthenogenesis where sexual crosses occur, but, in the absence of males, the diploid state is restored by reuniting sister chromosomes of a single meiosis. With a 54 Mbp genome, ''M. hapla'' represents not only the smallest nematode genome yet completed, but also the smallest metazoan.<br />
The ''M. hapla'' genome encodes significantly fewer genes than does the free-living nematode ''Caenorhabditis elegans'' (most notably through a reduction of odorant receptors and other gene families), yet it has acquired horizontally from other kingdoms numerous genes suspected to be involved in adaptations to parasitism. In some cases, amplification and tandem duplication have occurred with genes suspected of being acquired horizontally and involved in parasitism of plants. Although ''M. hapla'' and ''C. elegans'' diverged >500 million years ago, many developmental and biochemical pathways, including those for dauer formation and RNAi, are conserved. Although overall genome organization is not conserved, there are areas of microsynteny that may suggest a primary biological function in nematodes for those genes in these areas.<br />
