| Research Abstract |
The Antarctic nematode, Panagrolaimus davidi, is a remarkable organism that tolerates desiccation and intracellular freezing. To elucidate responsible genes for the tolerances, I have performed large-scale transcriptome and genome analyses in collaboration with the researchers in UK and New Zealand, and identified 25,875 transcripts. We picked up a candidate gene family for the tolerances, LEA genes, which are reported only from organisms living in extreme environments. Although even these special organisms have one or a few LEA genes normally, P. davidi has excess number of (at least 14 types of) LEA genes. Promotion of this research may facilitate the application to preserve internal organs and living bodies in frozen and/or dry state.
