CPL1/FRY2 Regulates ABA Biosynthesis and Modulates SA/JA-Mediated Defence in Arabidopsis.
It is demonstrated that CPL1 regulates ABA biosynthesis and modulates SA/JA-associated defence responses in Arabidopsis thaliana, positioning CPL1 as a key integrator of epigenetic regulation, hormone crosstalk, and pathogen-specific immune tuning.
