Differentially expressed genes among rice root types. Relative expression (scale bar, Z-scale of SDs from the cross-sample mean; blue, below the mean; yellow, above the mean) of 5,630 genes that are differentially expressed (FDR 10%) in crown roots (CRs), large lateral roots (LLRs), and fine lateral roots (FLRs) of rice. Both genes and samples are clustered hierarchically. A large group of genes is distinguished by high relative expression in CRs.
