Figure 5.

Hormone responsiveness of the five selected N/H-biclusters from N-bicluster 9. Centroid plots of the expression patterns for genes across the 5 significant (> 50% reproducibility; > 1.5 fold change) N/H-biclusters. Black bars below the plots indicate replicate experiments and grey bars indicate singleton experiments. N/H-biclusters 1 and 19 show a strong response to ABA treatment during seed imbibition (induction and repression respectively), N/H-biclusters 16 and 6 show an induction to cytokinin in roots and shoots of mutant and wildtype plants respectively. N/H-bicluster 20 shows a strong depression due to cytokinin in root tissues of mutant and wild type plants. Treatments are taken from the NASC data set: 1- Brassinolide 10 nM 3 hours (Seedlings), 2- ABA 3 μM 24 H (during Seed Imbibition), 3- ABA 30 μM 24 H (during Seed Imbibition), 4- Zeatin 20 μM 1 H (Seedlings), 5- Zeatin 20 μM 1 H (Shoots), 6- Zeatin 20 μM 1 H (Roots), 7- arr10/12 Zeatin 20 μM 1 H (Roots), 8- arr10/12 Zeatin 20 μM 1 H (Shoots), 9- AtIPT8/pga22 (Seedlings), 10- ga1–5 GA3 1 μM 0.5 H (Seedlings), 11- IAA 1 μM 0.5 H (Seedlings), 12- IAA 1 μM 1 H (Seedlings).
