Nurul Karim, John T Jones, Hiroaki Okada, Taisei Kikuchi BMC Genomics 2009, 10:525 (16 November 2009) Among 2,200 expressed genes identified in the fungivorus nematode Aphelenchus avenae, there are a set of genes encode cell-wall-degrading enzymes, indicating that this nematode also feeds on plants, and supporting the idea that plant parasitism has evolved from fungal feeding.

How do terrestrial Antarctic organisms survive in their harsh environment? David A Wharton, Craig J Marshall Journal of Biology 2009, 8:39 (29 April 2009) Wharton and Marshall discuss studies in BMC Genomics that identify genes and proteins involved in protecting Antarctic nematodes during desiccation, a strategy they developed to survive in a harsh environment.
