Expression pattern of three members of AtCBL gene family. (A) mRNA levels in leaves (lane 1), stems (lane 2), roots (lane 3), and flowers (lane 4). (B) mRNA accumulation under the stress conditions drought, cold, and wounding. A 10-μg sample of total RNA was loaded into each lane for RNA gel analysis using AtCBL cDNAs as hybridization probes.
