sugar-transport

2 articles

Sugar transport in plants refers to the movement of sugars—primarily sucrose—from sites of photosynthesis (source tissues) to sites of growth and storage (sink tissues) via specialized membrane proteins including SWEET transporters and SUT/SUC sucrose carriers. This process is fundamental to plant physiology, governing how carbon is allocated to developing seeds, roots, fruits, and other organs. Understanding sugar transport mechanisms has broad implications for improving crop yield, stress tolerance, and the manipulation of plant carbon partitioning for agricultural and biotechnological applications.
