Table 3 Cold stress related oat genes. Distribution of genes in the AsCIUniGene set into different functional categories. Functional class, determined as described in Methods; AsCIUniGene set, the set of 2800 different oat genes; CSDB, set of cold related genes extracted from the public domain; % CSR, relative number of oat genes in each family that is similar to cold related genes.
