Fig 2. Leaf shape diversity in Oryza.

Cluster analysis of species based on leaf blade length and leaf blade width generates two distinct groups of long and short leaved species, represented with a green background for long leaves and a yellow background for short leaves. Each species name is further accompanied with its genome type as mentioned in the text. The bar graphs show leaf blade width of long and short leaves separately to show the narrow and wide types. Representative photos of four leaf types in Oryza are shown as A = Long-wide (Lw), B = Long-narrow (Ln), C = Short-wide (Sw), and D = Short-narrow (Sn) leaf. Respective leaf types of Oryza species are mentioned in the black and white shaded boxes together with their preferred growing habitat, i.e., sunny/shaded. Notably, majority of the species in the first cluster are sun loving, whereas most of the species in the second cluster are shade loving. This suggests that sun-loving species mostly have long leaves whereas shade-loving species generally have short leaves.
