On April 3rd, the team of Prof. Xu Tongda of FAFU-UCR Joint Center for Horticultural Biology and Metabolomics of HIST published an online article titled “TMK1-mediated auxin signalling regulates differential growth of the apical hook”. The paper reported that a signalling mechanism operates at the concave side of the apical hook, and involves auxin-mediated C-terminal cleavage of transmembrane kinase 1 (TMK1).
Figures：
fig.a-d. TMK1 mediates the regulation of auxin on the development of apical hooks
fig.e-h. The cleavage by TMKI occurs under the action of high concentration of auxin on the inner side of the apex, and the C-terminal protein fragment is transferred to the cytoplasm and nucleus.
