摘要：
Cold-regulated (COR) genes are considered downstream functional genes in the cold-response pathway. However, we identified a plasma membrane-type, AtCor413pm1, as a regulatory gene for the abscisic acid (ABA) response, and found that ABA induced it predominantly in Arabidopsis roots, vasculature, stipules, and guard cells. Differentially expressed genes combined with qPCR analysis revealed the expressions of three ABA-responsive genes (AtDTX50, AtABR1, and AtCIPK20) were significantly altered in the ABA-treated atcor413pm1 mutant, compared to the wild-type. Furthermore, the ABA-induced transient Ca2+ oscillation in the plasma membrane of atcor413pm1 roots was different from that observed in the wildtype. Our results revealed that AtCor413pm1 might play a role in the cross-talk between the ABA and stress response pathways. (C) 2021 Elsevier Inc. All rights reserved.
