Data from: Cold-stress responses in the Antarctic basidiomycetous yeast Mrakia blollopis
Microbes growing at subzero temperatures encounter numerous growth constraints. However, fungi that inhabit cold environments can grow and decompose organic compounds under subzero temperatures. Thus, understanding the cold-adaptation strategies of fungi under extreme environments is critical for el...
