Table 4 Percentage of cold stress related sequences in different UniGene sets. UniGene specifies the different UniGene sets, which were: AsCI, Avena sativa cold induced; AsNI, Avena sativa non-induced; TaCI, Triticum aestivum cold induced; HvCI Hordeum vulgare cold induced. Amount, refers to the number of sequences that were analysed. In CSDB, indicates how many of the total genes that also were present in the collection of cold stress related genes. Cold related (%), gives the percentage of genes in each set that were cold stress related.
