Transcriptional responses to growth in high environmental calcium concentrations were characterized and compared between wild‐type and mutant Arabidopsis plants containing a knockout mutation in the gene encoding a cyclic nucleotide‐gated channel (CNGC2). We show that the transcriptional profile of cngc2 plants grown in normal media resembled that from wild‐type plants grown under elevated exogenous calcium conditions. The mutant grown in high‐calcium media exhibited transcriptional changes not seen in the wild‐type. The pattern of transcription suggests that adaptation to high external calcium overlaps with responses towards various biotic and abiotic stresses.
