Fig. 2From: Trait ontology analysis based on association mapping studies bridges the gap between crop genomics and PhenomicsComparisons of TO and GO analyses indicating that TAS-derived TO is an efficient alternative tool for functional analysis of genes. a b Bar charts of over-represented TO terms (left) and GO terms (right) for 145 plant height-related DEGs in maize (a) and kernel size-related genes in rice (b). The X-axis shows the percentage of genes and represents the abundance of the TO and GO terms. The percentage for the tested gene list was calculated as the number of genes mapped to TO or GO terms divided by the total number of all genes in the test list. The same calculation was employed for the background gene list. The Y-axis shows different TO and GO terms. (C) (D) False-positive rates of TO and GO enrichments in maize (c) and rice (d). The X-axis shows the number of randomly selected genes for the test, and the Y-axis shows the false-positive rateBack to article page
