Distribution of GOslim terms among individual genes. Histogram ofGOslim terms associated with all genes. Red bars indicate genes from multiple gene families (multiple) and blue bars represent genes from families with few members (single). Asterisks indicate comparisons where multiple gene families contained more (Red) or fewer (Blue) members than expected. Significance was judged at the 0.05 probability level (single asterisk) using a Chi-square test in each category. Double asterisks indicates significance at the 0.01 probability level. Genes from multiple member families are the predominant class of genes in each category. The pHaps were not randomly distributed among the GO categories with proteins involved in kinase, hydrolase, oxygen binding, transcription regulator, nuclease, signal transducer and transcription factor activities appearing to contain fewer members than the average multiple gene family while families in the categories of enzyme regulator structural molecule and catalytic activity and receptor, protein and lipid binding appear to have larger than average multiple gene families.
