Altitudinal differentiation in the leaf wax-mediated flowering bud protection against frost in a perennial Arabidopsis

An altitudinal gradient of leaf water repellency is often observed between and within species. In a previous study of Arabidopsis halleri, cauline leaves (stem leaves that wrap flowering buds) showed higher water repellency in exposed semi-alpine plants than in understory low-elevation plants.
