Fig. 2: Spatial variation of chloroplast clusters.
From: Spatial patterning of chloroplasts and stomata in developing cacao leaves
a–c Heatmaps visualizing the variation in chloroplast cluster sizes across interveinal segments within leaf groups G1–G4. Darker green indicates larger average chloroplast cluster size. d Combined data from all leaves in groups. Capital letters (A, B, C) denote significant differences in chloroplast cluster size frequency between segments (Tukey’s HSD test, p < 0.0001). Scale bars = 1 cm. Sample sizes: a 2339, b 3978, c 1335, d 7652.
