| molecular evolution in panagrolaimus nematodes: origins of parthenogenesis, hermaphroditism and the antarctic species p. davidi. | as exemplified by the famously successful model organism caenorhabditis elegans, nematodes offer outstanding animal systems for investigating diverse biological phenomena due to their small genome sizes, short generation times and ease of laboratory maintenance. nematodes in the genus panagrolaimus have served in comparative development and anhydrobiosis studies, and the antarctic species p. davidi offers a powerful paradigm for understanding the biological mechanisms of extreme cold tolerance. ... | 2009 | 19149894 |
