On the basis of recent cladistic analysis it is possible to predict that the synthesis of these compounds is a characteristic of the Angiosperms. Highly specific and sensitive bioassays and analytical procedures of high resolution are now available which may allow confirmation of this hypothesis. Solanum glaucophyllum is the species which accumulates 1a,25(OH)D3 to the greatest extent.

The presence of 7-dehydrocholesterol, vitamin D3, 25(OH)D3 and 1a,25(OH)2D3 in S. glaucophyllum and other species has been unequivocally demonstrated. Moreover, recent studies with radioactive precursors, protein immunoblot and RNA hybridization analysis suggest the presence of specific hydroxylases for vitamin D3 and 25(OH)D3 structurally related to the corresponding enzymes in vertebrates. It appears then that plants possess a similar synthetic route to 1a,25(OH)2D3 as in animals. However, of unique biological importance, evidence obtained with S. glaucophyllum and Nicotiana glauca supports the operation of a non-photolytic reaction of vitamin D3 synthesis. Both intermediates and enzymes of the vitamin D3 pathway can be detected in cell and tissue cultures thus affording a convenient experimental model for studies on its molecular characterization and regulation. This is also endowed with biotechnological significance. Vitamin D3 compounds may play a function in Angiosperms. Studies in vitro have shown that, like mitogenic plant hormones, they stimulate root growth and differentiation through activation of the Ca2 messenger system.
