1 We observed that gpa1 mutants are disrupted both in ABA-induced Ca(2+)-channel activation, and in production of reactive oxygen species (ROS) in response to ABA. Reactive Oxygen Species G protein alpha subunit 1 Arabidopsis thaliana
2 We observed that gpa1 mutants are disrupted both in ABA-induced Ca(2+)-channel activation, and in production of reactive oxygen species (ROS) in response to ABA. Reactive Oxygen Species G protein alpha subunit 1 Arabidopsis thaliana
3 These data indicate that absence of GPA1 interrupts ABA signalling between ABA reception and ROS production, with a consequent impairment in Ca(2+)-channel activation. Reactive Oxygen Species G protein alpha subunit 1 Arabidopsis thaliana
