  1. Proteins were classified using the Gene Functional Annotation Tool of DAVID bioinformatics resources. a. Gene Ontology; b. Ratios are negative where the number of proteins down-regulated at 25°C (# DN) > the number of proteins up-regulated at 25°C (# UP) and positive where # UP > # DN; c. % = the number of proteins in this category out of 178 proteins; d. Modified Fisher Exact P-value (probability of obtaining this many differentially expressed proteins in the category by chance); e. Fold-enrichment; f. GO Molecular Function term. g. GO Cellular Component term.
