- The ERECTA (ER) receptor kinase and its homologs ERL1/ERL2 have pleiotropic roles in plant development, including vascular cambium activity.
- In the vascular cambium, ER family members form protein complexes with PXY and PXL proteins to regulate cambium activity.
- Genetic analyses show that constitutive PXY signaling requires ER or ERL2 to cause dramatic cambial phenotypic changes.
- This PXY-ER complex interaction explains ER function in the cambium, impacting wood production and carbon sequestration.
