The brightest and most vivid colours in nature arise from the interaction of light with surfaces that exhibit periodic structure on the micro- and nanoscale. In the wings of butterflies, for example, a combination of multilayer interference, optical gratings, photonic crystals and other optical structures gives rise to complex colour mixing. Although the physics of structural colours is well un...

MS liquid medium supplemented with 3 mg/l NAA and 1 mg/l BAP with pH 5.7 was used for suspension cultures. Suspension cultures subjected to biotic elicitors Aspergillus niger, Fusarium oxysporium, Rhizopus oryzae and Penicillium notatum induced increase in forskolin content. Among all the elicitors tried Aspergillus niger proved to be best elicitor at 5% CF which was 6 times higher than the con...

Seedlings of wheat (Triticum aestivum L.) were grown in special holders that permitted the coleoptile and early roots to develop in moist air. The orientation of the organs of seedlings erect to gravity was compared with that of organs produced on a horizontal clinostat. Orientation was described by the angular position of each organ tip with reference to the axis of the embryo. Comparative tes...

Miana (Coleus atropurpureus L. Benth) is a plant in the ornamental group that has benefits for body. The part of efficacious as medicine on leaves with brownish red color. However, extracts from miana are hydrophilic, making it difficult to penetrate biological membranes which rich lipids and use topically. One way overcome this problem by liposome carrier systems. Liposomes systems consisting ...

Forskolin is a unique structurally complex labdane-type diterpenoid used in the treatment of glaucoma and heart failure based on its activity as a cyclic AMP booster. Commercial production of forskolin relies exclusively on extraction from its only known natural source, the plant Coleus forskohlii, in which forskolin accumulates in the root cork. Here, we report the discovery of five cytochrome...
