Influence of seasonal and latitude changes in solar radiation on the synthesis of plastid pigments

In the presented work, using the example of carotenoids and tetrapyrroles, the environmental conditionality of plastid pigment synthesis is substantiated. In the homologous series of the genus Viola, it is shown that the genetically determined synthesis of carotenoids and tetrapyrroles is an adaptation to the circadian rhythms of solar radiation and to variations in its quantitative and qualitative characteristics. An attempt is made to expand the area of prediction of the homological series law in hereditary variability, namely, knowing expression of the morph-forming factor for the homological series of one species, one can assume the time and location of parallel forms in other related species.
