Production of plant growth inhibitors from xanthophylls: a possible source of dormin 

 -  Nature, 215(5109), p.1513-1514, 1967 .
<br/><br/> THE plant growth inhibitor, dormin, shows similarities in structure to certain carotenoids and, because there is evidence that light stimulates the production of inhibitor ß (refs, 1 and 2), the principal activity of which is probably caused by dormin3,4, we have studied the possible formation of inhibitory substances by illumination of these pigments.
