[Melanin pigments of fungi under extreme environmental conditions (review)].

This review is dedicated to the research on the functions of melanin pigments in fungi. The participation of melanin pigments in protection from environmental factors is considered. Data on the biosynthetic pathways and types of melanin pigments in fungi are presented.

[Fungal anthraquinones (review)].

The review is devoted to the characteristics of anthraquinones--a group of pigments of quinoid nature often found in fungi. The distribution of anthraquinones in fungi, the routes of their biosynthesis, and their biological activity are considered.

[Comparative analysis of respiratory activity in the wild type strain of Neurospora crassa and its photoreceptor complex mutants].

Cell respiratory activity of protoplasts obtained from the wild type of Neurospora crassa and photoreceptor complex WCC--white collar 1 (wc-1) and white collar 2 (wc-2)--mutants of Neurospora crassa strains was investigated. Respiration inhibition by KCN in the presence of 25 mM succinate was similar in all strains and did not exceed 83-85% against control. The significant induction of KCN-resistant respiratory pathway occurred under 1% glucose oxidation in wc-1 and wc-2 mutants if compared with the wild type strains.

[A comparative investigation of adaptation to oxidative stress factors a strain of mycelial fungus Paecilomyces lilacinus from Chernobyl Atomic Energy Station and strains of the same species from territories with basic level of radioactive pollution].

An oxidative stress resistance in Paecilomyces lilacinus strain from Chernobyl Atomic Energy Station (ChAES) as well as in P. lilacinus strains from zones with control level of radioactive pollution has been studied. It was shown that radial growth rate of the colony of the ChAES strain in a range of glucose concentrations 0.
