Outline of Final Research Achievements |
Environmental signals such as desiccation, hyperosmosis and low temperature affect levels of the stress hormone abscisic acid (ABA), which plays a key role in protection of cells from stress-induced lethal damage. How different environmental signals as well as the ABA signal are integrated to control genes necessary for the cellular tolerance has not been understood. To elucidate mechanisms underlying autonomous responses of plant cells to various environmental stress signals, our study will focus on identification a signaling factor integrating stress signals by analysis of mutants of bryophytes. We identified a Raf-like kinase designated ARK and analyzed interactions between the identified factors and known signaling factors to determine a series of processes necessary for integrative control of the signals.
