Outline of Final Research Achievements

Plants have evolved “tolerance module”, which is consisted of a set of tolerance genes regulated by core transcriptional regulator. STOP1 is a zinc-finger protein of Arabidopsis, and regulates modules for acid and aluminum tolerance, which are essential for surviving in acid soils. Current study, we identified “STOP1-regulating module” from pigeon pea, which is consisted of citrate-transporting MATE and ALS3. In addition, we identified molecular mechanisms of regulatory mechanisms of STOP1, including transcriptional regulation of AtALMT1.
