Other claims from this paper (6)
- Mechanism Wheat PM H+-ATPase TaHA2 was identified as a key regulator of apoplastic pH and defense responses to Pst infection.
- Intervention effect Overexpression of TaHA2 exacerbated apoplastic acidification and susceptibility to Pst.
- Intervention effect CRISPR-Cas9 inactivation of TaHA2 in wheat did not compromise agronomic traits.
- Mechanism TaCIPK9 phosphorylates TaHA2 at Ser-933, triggering intramolecular interactions that suppress TaHA2 activity.
- Mechanism The Pst effector PstCFEM2 competitively binds the C-terminus of TaHA2, disrupting TaCIPK9-mediated phosphorylation and relieving autoinhibition.
- Mechanism Effector-driven activation of TaHA2 amplifies apoplastic acidification and stomatal opening, ultimately dampening plant immunity.
