Photosynthetic Pigmentation: Variegations on a Theme [PDF]

open access: yesThe Plant Cell, 1999
Plant pigmentation has been of major interest to horticulturists for millennia. The ancient Egyptians, for example, cultivated the madder plant ( Rubia tinctorum ) as a source of dye for the ornamentation of mummies, and tribal peoples living before the Common Era in northern Britain tattooed ...
