This pathway is essential for the efficient movement of sugars to the stolons (the stems that become tubers), which is necessary for healthy tuber development.
: Suppression of miR166 in stable transgenic lines results in significantly altered productivity, specifically impacting how many tubers a plant produces and their individual weight. Molecular Mechanism : 139707 zip
: The miR166-HD-ZIP III regulatory module is a critical determinant of tuber shape. Disrupting this module leads to distorted tuber growth and changes in internal xylem structure. This pathway is essential for the efficient movement
: The research identifies how this module influences the pigment (anthocyanin) accumulation in tubers, which affects their final color. Disrupting this module leads to distorted tuber growth
The module regulates the expression of , which in turn binds to the promoters of sugar transporters like SWEET11 and SWEET12 .
