OsCam and OsCML transcript expression in response to stress. (A) Microarray based transcript expression profiles under dehydration (drought) and salt stress shown as a heat map. Transcript expression levels examined in the KDML105 rice cultivar under osmotic stress (B) and salt stress (C) showing relative transcript expression levels standardized to that of OsEF1α and expressed relative to the levels on day 0 of the treatment. Rice seedlings were grown in a CRD with three replicates, and for each replicate, ten seedlings were pooled for RNA extraction. The PCR reaction of the same cDNA preparation was performed in triplicate for technical replication. Data are shown as the mean ± 1 SD and means with a different lowercase letter are significantly different (p < 0.05).
