of the photoreceptor pigment, phyto- chrome, constitutes one of the great achievements in modern biology. It was primarily a group of investigators at the Plant Industry Station, Beltsville, Mary- land, headed by the botanist H.A. BORTHWICK and the physical chemist S.B. HENDRICKS, who made the basic

Phytochrome-mediated Enzyme Induction,ell can rapidly (i.e. in a matter of minutes, not hours) mediate enzyme induction as well as enzyme repression (Fig. 75). Further, we had to postulate enzymes whose synthesis or decay is not affected by P.. This 6. lecture will be concerned with the problem of verifying this model using the mustard seedling as our experimental material.

Repression of Lipoxygenase Synthesis by Pfr: The Problem of Primary and Secondary Differentiation, control mechanism in development of multicellular systems. A clear comprehension of the various aspects of this problem is necessary if speculations about the molecular mechanisms that control the epigenesis of higher forms [26] are to be consistent with the available facts.

Light-mediated Flavonoid Synthesis: A Biochemical Model System of Differentiation,tiation involves cellular specialization and occurs by the selective loss and acquisition of specific structures and functions. Morphogenesis involves the arrangement of cell populations in a precise and organized fashion in space and time.
