Abstract

In order to estimate how diverse the mating types in Pleurotus eryngii from different regions are, pairings between monokaryons derived from inter- and intragroups were done. Sixteen and 15 alleles were identified at loci A and B from the 12 strains. In the P. eryngii KNR2312, widely used for commercial production, four mating loci, A3, A4, B3, and B4, were determined. Those loci, except A3, were found in 4 strains out of 12 strains. To improve breeding efficiency, especially in mating type determination, RAPD and BSA were performed to screen for a mating type specific marker. The SCAR marker 13- 2(2100) was developed based on the RAPD-derived sequence typing B3 locus. The sequence analysis of 13-2(2100) revealed that it contained a conserved domain, the STE3 superfamily, and consensus sequences like the TATA box and GC box. It seems likely that the SCAR marker region is a part of the pheromone receptor gene.

Nutritional and medicinal Importance of Pleurotus mushrooms: An Overview

چکیده

Mushrooms of Pleurotus genus are popularly consumed all over the world due to their taste, flavor, high nutritional values and some medicinal properties. Several species of this genus are rich in proteins with essential amino acids, physiologically important polysaccharides and essential fatty acids, dietary fibers, important minerals and some vitamins. Because of these nutritional composition and the presence of some other active ingredients, these mushrooms have been reported to have anti-cancer, anti-hypercholesterolemic, anti-hypertensive, anti-diabetic, anti-obesity, hepato-protective, anti-aging, anti-microbial, anti-allergic and antioxidant activities. The high nutritional value and potential medicinal uses suggest that the Pleurotus mushrooms are important functional foods or nutraceuticals.
