Table 1 Summary and analysis of EST database search results. Search results from all eight databases are summarized, including database size and number of ESTs showing significant similarity to each MST subfamily on BLASTX search for each taxon. For the five large databases (>100,000 ESTs), the percentage of subfamily ESTs as a proportion of total MST ESTs, the percentage of MST ESTs as a proportion of total ESTS, and the number of expressed loci is shown.

From: The monosaccharide transporter gene family in land plants is ancient and shows differential subfamily expression and expansion across lineages
