    Area of Science:

    • Cell Biology
    • Molecular Biology
    • Plant Science

    Background:

    • Vesicle trafficking and fusion are fundamental cellular processes essential for numerous cell functions.
    • The molecular machinery governing vesicle fusion is conserved across eukaryotes but exhibits lineage-specific expansions and specializations.
    • Understanding these specialized regulators is key to deciphering unique cellular processes.

    Purpose of the Study:

    • To investigate the function of the SEC1 family protein KEULE in plants.
    • To elucidate the role of KEULE in plant cell cytokinesis.

    Main Methods:

    • Utilized genetic analysis in the model plant Arabidopsis thaliana.
    • Investigated the function of KEULE, a member of the SEC1 family of proteins.
