The Antarctic nematode Plectus murrayi: an emerging model to study multiple stress survival.
Cold Spring Harbor protocols, 2010Co-Authors: Bishwo N. Adhikari, Cecilia Milano De Tomasel, Diana H. Wall, Byron J. AdamsAbstract:The genus Plectus is one of the most widely distributed and common nematode taxa of freshwater and terrestrial habitats in the world, and is of particular interest because of its phylogenetic position relative to the origin of the Secernentean radiation. Plectus murrayi, a bacteria-feeding nematode, inhabits both semi-aquatic and terrestrial biotopes in the Antarctic McMurdo Dry Valleys (MCM), where its distribution is limited by organic carbon and soil moisture. Plectus nematodes from the MCM can survive extreme desiccation, freezing conditions, and other types of stress. Ongoing investigations of the physiological and molecular aspects of the stress biology of P. murrayi, along with the availability of genomic resources, will likely establish this nematode as an excellent invertebrate model system for studies of extreme environmental survival, and may provide a valuable source of genomic resources for comparative studies in other organisms. Moreover, because P. murrayi and Caenorhabditis elegans share a most recent common ancestor with the rest of the Secernentea, and given the ability of P. murrayi to be cultured at lower temperatures compared to C. elegans, P. murrayi could also be an emerging model system for the study of the evolution of environment-sensitive (stress response) alleles in nematodes.

Descriptions of six known species of Plectus Bastian, 1865 (Nematoda, Plectida, Plectidae) from India with a discussion on the taxonomy of the genus
Zootaxa, 2012Co-Authors: Qudsia Tahseen, Malka MustaqimAbstract:Detailed descriptions of six species of Plectus reported for the first time from India are given on the basis of LM and SEMobservations. Plectus geophilus de Man, 1880, P. aquatilis Andrassy, 1985, P. parvus Bastian, 1865, P. minimus Cobb,1893, P. magadani Kuzmin, 1979 and P. communis Butschli, 1873 are described and illustrated. The salient morphologicalcharacters of the species are given. The taxonomy of the genus has been discussed along with the status of species pre-senting a great degree of morphometric overlap and continuous variation. An emended diagnosis of the genus is provided with incorporation of relatively consistent and less variable characters.
