Fig. 6: Proposed models of factors contributing to starch gradients in wheat caryopses.

From: Transport and spatio-temporal conversion of sugar facilitate the formation of spatial gradients of starch in wheat caryopses

Fig. 6

The sucrose concentration is presented as the number of orange circles modified from the PET-CT results (Fig. 2). The black arrows indicate the transport pathway of sucrose in the caryopsis from the cavity to the aleurone via the transferred cells. The number of green cubes is used to indicate the expression levels of sucrose transporters according to the qRT‒PCR results (Fig. 5). Sucrose metabolism and starch synthesis ability in different parts of the caryopsis are indicated by the thickness of the red arrows. The contents of amylose and amylopectin are shown as different shades of blue. The transverse section is from the developing grain of wheat at 15 days. AL aleurone, OE outer endosperm, IE inner endosperm, TC transfer cells, SG starch granule, s sucrose. Scale bar = 30 μm.
