| Research Abstract |
Molecular genetic and molecular biological analyses of several novel Arabidopsis mutants that impair the abscisic acid (ABA)-response allowed us to describe the ABA signal transduction pathway from perception to nuclear events and find the novel relation between ABA response and mitochondrial function. These findings offer a new avenue for understanding the cellular response mechanisms to ABA.
