AraNet correctly associates genes with many processes unique to plants, nonetheless relying at least in part on data from animals and yeast, which contribute evidence for linkages among genes that are broadly conserved but whose roles in Arabidopsis are in plant-specific processes. The performance at associating genes with each of 29 biological processes specific to plants (annotated only with plant genes in GO and are known to occur only in plants) is summarized as the area under a cross-validated ROC curve (AUC). Even though these processes are absent in animals or fungi, the associated genes often have orthologs in these taxa, and AraNet draws upon data from these orthologs in making the associations. Each gray square demarks the support provided by a dataset, measured as a sum of log likelihood scores contributing to that process, with darker gray indicating higher support. Datasets are labeled as in Figure 1.
