Fig. 4: Characterization of F. vesca fveagl62 mutant seedcoat.
From: Mechanism of fertilization-induced auxin synthesis in the endosperm for seed and fruit development
a Vanillin-stained F. vesca WT and fveagl62 mutant seeds at the pre-fertilization stage 1 and post-fertilization stages 2–3. The proanthocyanidins in the endothelium layer stains red with the vanillin. b Confocal laser scanning microscopy images of WT and fveagl62 seeds at stage 2. The enlarged box highlights the three integument cell layers (red arrows) exterior to the endothelium. Scale bars, 500 μm (a), 100 μm (b).
