Summary of functional information for Gene Ontology categories upregulated or downregulated during desiccation stress. Only categories with enrichment scores >3.0 (corresponding to P<0.001) are included. More information on genes included in these categories and GO clusters with lower enrichment scores are included in Supplementary Tables S2 and S3.
