Do plants wear sun-block?

A growing body of evidence suggests that plants alter their chemical composition in relation to the amount of incoming solar radiation (“insolation“) they are exposed to during life.  Chemical changes are induced in order to provide protection against the deleterious effects of ultraviolet (UV)…
