Functional categorization of assembled unigenes based on Gene Ontology (GO) classification in leaves of two tall fescue genotypes (heat-tolerant PI 578718 and heat-sensitive PI 234881). (a) functional categorization of entire genes for all treatment lines of two genotypes (green bars); (b) functional categorization of genes for 36 h heat-stressed PI 578718 and PI 234881. The unigenes were summarized in three main GO categories (biological process, cellular component and molecular function) and 49 subcategories. The y-axis indicates the number of unigenes in each class and the x-axis indicates the subcategories.
