Confirmation of co-expression of HvCslF3 and candidate genes. In panel A the Q-PCR expression profiles of the cellulose synthase-like gene HvCslF3 and the candidate genes identified in this study are compared. Expression profiles have been standardized as described in the text. As can be seen, the genes indeed co-express in the tissues probed in both the Q-PCR and microarray datasets. Panel B shows an additional comparison of Q-PCR coleoptile time course expression profiles of HvCslF3 and Contig11619. The two genes appear to remain roughly co-expressed in this time-course as well.
