aObserved number of genes and expected number of genes if probabilities of each outcome are independent of the cluster.
bNumber of gene orothologs in each of the expression profile groups.
cHypergeometric probability was used to obtain the P-value using fisher.test( ) in R (bioconducter.org).
dFour groups of differentially expressed genes in relation to dormant spores were reported.
eGenes were grouped into three clusters according to their expression profiles by K-means algorithm.
fNumber of gene orthologs in each of the hierarchical clusters.
