Differential expression of the maize B73 cellulose synthase (CesA) gene family members during stem development. Transcript levels in rind tissues from Internodes 9 through 2 were normalized and compared as counts per 20 M reads. Values are the mean ± variance or S.D. of two or three independent rind collections, respectively. Genes with expression greater than 500 reads per 20 M were ordered by their ratio of expression (black diamonds) in secondary cell-wall-forming tissues (Internodes 5 through 3) to elongating tissue (Internodes 9 and 8). Blue text indicates the closest Arabidopsis homolog to the maize gene is similarly expressed constitutively or in elongating rind tissues, and red text indicates that the closest Arabidopsis homolog to the maize gene is similarly expressed in secondary cell-wall-forming tissues
