Description
Ryszard Zamorski and co-authors present a 2023 study of why some rice varieties store a wall sugar called glucomannan in their grains while others store none. Cell walls shape plant growth and the quality of food and materials made from plants. How wall makeup varies within one species was poorly understood.
Under the microscope, grain walls from many varieties fell cleanly into two groups: with the sugar or without it. The sugar made up a tenth or more of the starchy walls where present and sat close to cellulose fibres. Gene comparisons pointed to one gene whose form differed sharply between the two groups. Finding the exact gene could guide breeding for grain quality.
