A short review on the history of pigment cell research at Charles University (Ch. U.) in
Prague is presented. The famous Czech physiologist and professor JE Purkyne started the …

Fungi possess all kinds of melanins found in nature. These pigments are products of
polymerization of phenolic compounds. Phenolic precursors determine the polymerization …

The polyquinoid nature of eumelanin (s) enables them to couple oxidation of electron
donors with the reduction of electron acceptors. We have studied the ability of synthetic …

In recent years the melanins have been widely investigated. They have many interesting
properties; one such property is their behavior in the solid state domain as semiconductors …

Publisher Summary The cells of many fungi, like those of some other heterotrophic
microorganisms, bear photoreceptor mechanisms through which light may control certain …

Light‐induced EPR signals can be observed in moss spores and pollen grains. Their
characteristics are studied in this paper. The modification of these signals during spore …

As far as we know at present photomorphogenesis (including light-induced carotenoid
synthesis) in fungi is exclusively mediated by a photoreceptor pigment which absorbs only in …

Short wavelength visible light is viewed as the main agent responsible for oxidative
modification of melanin in the human retinal pigment epithelium (RPE). The aim of this …

DURING an investigation on the appearance of red-pigmented patches on chrome-tanned
hide it is found that this pigmentation is caused by the growth of Penicillium rubrum Stoll on …
