[HCG34-P04] Analysis of proteins involved in processes of desiccation and rehydration in a terrestrial cyanobacterium, Nostoc sp. HK-01.
Keywords:cyanobacteria, desiccation tolerance, stress protein
Initially, to investigate expression changes of genes in Nostoc sp. HK-01 during dehydration, proteins extracted from Nostoc sp. HK-01 cells on the way the dehydration were analyzed by SDS-polyacrylamide gel electrophoresis. The cells were dried in a desiccator. Next, proteins extracted from the cells during rehydration were analyzed.
In the course of desiccation and rehydration of the cells, the expression level of some proteins changed. Some of them were insoluble proteins, and others were soluble proteins. These proteins could be involved in desiccation tolerance of Nostoc sp. HK-01.
