Arabidopsis CAP1 interacts with myosin XI-K to regulate root hair tip growth.

Plant physiology and biochemistry : PPB - 1 Mar 2026

Zhou Xuedan, Guo Wenhui, Du Jiashun, Wu Lulu, Ma Xiaonan, Bai Ling

Abstract excerpt

Root hair serves as a classical single-cell model system for studying polarized cellular growth. Our prior work established Calcium-Associated Protein Kinase 1 (CAP1) as an essential regulator of Arabidopsis root hair tip growth, with cap1-1 mutants display stunted and aberrant root hair. Phosphoproteomic analysis identified ‌myosin XI-Kas a putative substrate of CAP1, we here decipher the molecular mechanism...
