The data were obtained from microarray experiments using a total of three independent preparations of RNA per line prepared from plants grown in controlled environment conditions (see Methods). Locus identifiers in bold indicate genes with altered expression only in rax1-1. The numbers in parentheses are the same comparisons conducted using a qRT-PCR procedure for that gene with two replicate RNA preparations independent of those used for the microarray experiments. n.d., not detected; –, not determined.
