Analysis of representative ' slow early response ' genes (Group-II) including OsMyb4 , EREBP1-type protein, high mobility group (HMG) protein, ferritin, and putative ATP sulfurylase. (A) Expression profiles based on qPCR showing the induction peak(s) of the Group-II genes towards the end of the 24 hours incubation at 10°C. Expression signature of the tolerant (CT6748-8-CA-17) and intolerant (INIAP12) cultivars are shown. Transcript level at each time point was normalized against the expression of constitutively expressed actin gene. Relative expression of control (0 hour; not shown in the graph) was set to zero by subtracting from the relative expression values of each time points. Relative expression values are averages of independent replicates (n = 3; ± SE). (B) Promoter maps of representative Group-II genes showing the relative position and distribution of known stress-responsive cis-element motifs. The as1/ocs-like motifs are the prominent family of elements in this group of genes.
