Covariance analysis of kiwifruit AcGRAS genes. Gray lines indicate all duplicated genes, dark green indicates fragmented duplicated GRAS gene pairs, and red lines connecting genes outside the chromosome indicate tandem duplicated pairs. The heatmap and line graph are gene densities, with line graph densities increasing from blue to white to red, and yellow rectangles are chromosomes, with chromosome names shown between each chromosome and gene density
