Genome-Wide Identification and Characterization of the ALOG Domain Genes in Rice

Genome-wide expression profiles and qRT-PCR analysis of OsG1/G1Ls. (a) The hierarchical clustering displays the expression profiles of the 11 OsG1/G1Ls using the matching probes in the Affymetrix microarray. The color scale at the left bottom represents the log₂-transformed expression values. Cyan indicates a low expression level, black indicates a medium expression level, and red indicates a high expression level. The thirty-three samples of MH63 and ZS97 were sequentially marked as M1 to M33 and Z1 to Z33 on the x-axis, respectively. The detailed sample information was listed in Supplementary Table S1. (b) qRT-PCR analysis of 9 OsG1/G1Ls. The twelve analyzed samples were indicated as Z4 to Z31 on the x-axis because they were sampled according to the tissues and developmental stages in the microarray (see Supplementary Table S1). The values on the y-axis represent the relative expression levels. The error bars represent the standard deviation of the means of three independent replicates.
