The expression patterns in different tissues for Arabidopsis and rice AGP-encoding genes. AGP-encoding genes are presented in the same order as in the corresponding phylogenetic trees. The expression data of AGP-encoding genes in different tissues were combined from microarrays and MPSS tags. The expression data in pollen of rice AGP-encoding genes were extracted from MPSS tags. Letters on the top indicate different tissues and databases. M1 and M2 represent microarrays and MPSS tags, respectively. The ratios of the absolute values divided by the average of all microarray values were used for analysis (Supplementary Table S5 at JXB online). Light grey, dark grey, and black boxes indicate low (between 0.5 and 1 or the signature numbers between 0 tpm and 50 tpm), moderate (between 1 and 2 or between 50 tpm and 500 tpm), and high (>2 or >500 tpm) expression levels, respectively. The white boxes indicate that no expression could be detected (<0.5). ‘×’ represents no probe or signature on microarray and MPSS. SF, subfamily; R, root; L, leaf; I, inflorescence; Po, pollen; S, silique or seed.
