The maltose-related starch degradation pathway promotes the formation of large and spherical transitory starch granules.

The Plant journal : for cell and molecular biology - 1 Oct 2024

Abstract excerpt

Previously, in Arabidopsis thaliana, we found atypical spherical starch granules in dpe2ss4 and dpe2phs1ss4. However, the mechanism of such abnormal morphogenesis is still obscure. By tracking starch granule length and thickness with leaf ageing, we reported that the starch granules in dpe2phs1ss4 gradually change to a spherical shape over time. In comparison, Col-0 and the parental line ss4 did not exhibit...
