Determination of gene function is particularly problematic when studying large gene families
because redundancy limits the ability to experimentally assess the contributions of individual genes.
Phylogenomics is a phylogenetic approach used in comparative genomics
to predict the biological functions of members of a large gene families by assessing the similarity
among gene products. Recently, we reported the development of phylogenomics databases for 1,508 rice
kinases (Rice Kinase Database, RKD) and 769 glycosyltransferases (
Rice Glycosyltransferase Database, RGTD)
(Dardick et al, 2007 Plant Physiology; Cao et al., 2008 Molecular plant; Cao et al, Bioenergy Research, in press).
We have also constructed the following databases:
