Abscisic acid–regulated stability of CmABF1 and CmBRM modulates salt tolerance in chrysanthemum via epigenetic regulation of CmHSFA4
It is shown that salt stress–induced ABA accumulation up-regulates Heat Shock Factor 4 (CmHSFA4), a gene that is known to enhance chrysanthemum salt tolerance, and an ABA-SnRK2.2-ABF1/BRM signaling module that integrates phosphorylation-dependent protein stabilization and degradation with histone methylation dynamics to fine-tune salt stress–responsive gene expression in chrysanthemum is revealed.
