Overview of the auxin response genes in moso bamboo. Six samples from auxin treated and mock treated moso bamboo roots collected and were subjected to RNA-Seq analysis. Heatmap representation and hierarchical clustering of the differentially expressed transcript clusters for the up-regulated (a) or down-regulated (c) in response to auxin treatment are shown. Numbers on the nodes display major gene groups based on expression patterns. Color scale shows log2 signal intensity values. GO enrichment analyses for up-regulated genes (b) and down-regulated genes (d) in response to auxin. Best hits were aligned to the GO database, and most consensus sequences were grouped into three major functional categories: biological process, cellular component, and molecular function. Red indicates up-regulated genes; green indicates down-regulated genes
