CPR5 acts upstream of IRE1, bZIP60 and bZIP28 in the control of plant growth under the endoplasmic reticulum stress response.
(a), (c), (e), (g), (i), (k) Seedlings were germinated on 1/2 Linsmaier and Skoog medium containing 50 ng ml−1 tunicamycin (Tm) for 12 days vertically. White dashed line, length of the primary roots grown under normal growth conditions as shown in Figure 2(a, d, g) and Figure 3(a, d, h). Red dashed line, length of the primary roots grown with Tm treatment.
(b), (d), (f), (h), (j), (l)) Relative growth values of seedlings as indicated in (a, c, e, g, i, k). LOPR, length of primary root; NOLR, number of lateral roots; SFW, shoot fresh weight; Wt, wild type. Error bars represent SD; n = 24 for each genotype. *P < 0.05; **P < 0.001; ***P < 0.0001; ns, not significant.
