A professional BioRender-style mechanistic diagram illustrating the impact of post-anthesis high-temperature stress on colored wheat grains. On the left, a stylized icon of a sun/heat wave representing "High Temperature Stress" with a red arrow pointing to a molecular pathway. The pathway features key enzymes: PAL, CHS, and DFR. Red inhibitory T-bars (flat-headed arrows) from the heat source to these enzymes. Downstream, icons representing 6 anthocyanin types (Cyanidin, Delphinidin, Pelargonidin, etc.) showing reduced accumulation. The background is clean white. High-quality vector graphics, soft professional colors (muted blues, purples, and reds), 2D flat design, clear labeling of enzymes in simple sans-serif font.
