Anhydrobiosis is survival of complete body desiccation, tightly linked to the ability to cope with a massive DNA damage. However, in anhydrobiotic midge Polypedilum vanderplanki this ability is not accompanied by a huge induction of genes of DNA reparation system which is typical for many other anhydrobiosis-related genes in this insect.

Thank You for the brilliant work and presentation!
As far as I know, DNA restoration processes after desiccation may take up to 4 days to complete in some cases. Could it be possible that such low activity of DNA reparation processes is related to the early capture of gene expression levels during rehydration?
