“…When the PIC value ranges between 0.00 and 0.25, it indicates very low genetic diversity among the samples. The value between 0.25 and 0.50 shows a medium level of diversity, and the value more than 0.50 suggests a high level of genetic diversity (Smith et al 1997;Tams et al 2005;Qiu et al 2014). The moderate genetic diversity detected in these Cenchrus accessions indicates the necessity to include more diverse natural germplasm accessions in the breeding programs.…”

Analysis of genetic diversity is important for plant breeders to breed new and improved cultivars with desirable characteristics. Since DNA-based molecular markers are not affected by environmental factors, they can be utilized to assess genetic diversity among species and to develop molecular markers for breeding programmes. Out of the 25 Cenchrus species, only eight are available in the Indian germplasm collections, and only four of them are grown in sown pastures for their high forage value, while the remaining four species are used for basic and applied studies. This study aimed at assessing genetic diversity and relatedness of the apomictic and sexual Cenchrus species available in the Indian germplasm collection using AFLP-based molecular markers. Based on the genetic dissimilarity matrix phylogenetic analysis, 36 accessions of eight Cenchrus species were observed to be clustered in four groups. All apomictic C. ciliaris L. accessions clustered within a group, while the other three apomictic Cenchrus spp. grouped separately. Similarly, the rare accessions of sexual C. ciliaris grouped separately from the sexually reproducing Cenchrus spp. However, Bayesian cluster analysis grouped the 36 accessions in three clusters only. Clustering of the accessions of phylogenetic Groups 1 and 2 was similar in Bayesian cluster analysis, while the accessions of Groups 3 and 4 clustered together. Some of the AFLP markers were observed to delineate the apomictic and sexual species/ accessions of Cenchrus. The gathered information has the potential to be used for genetic improvement of Cenchrus species through cross-hybridization to exploit hybrid vigour as well as for introgression of desirable traits.

Here, we report the current status of the bioactive peptides isolated and characterized from mushrooms during the last 20 years, considering ‘peptide’ a succession from to 2 to 100 amino acid residues. According to this accepted biochemical definition, we adopt ~10 kDa as the upper limit of molecular weight for a peptide. In light of this, a careful revision of data reported in the literature was carried out. The search revealed that in the works describing the characterization of bioactive peptides from mushrooms, not all the peptides have been correctly classified according to their molecular weight, considering that some fungal proteins (>10 kDa MW) have been improperly classified as ‘peptides’. Moreover, the biological action of each of these peptides, the principles of their isolation as well as the source/mushroom species were summarized. Finally, this review highlighted that these peptides possess antihypertensive, antifungal, antibiotic and antimicrobial, anticancer, antiviral, antioxidant and ACE inhibitory properties.

“…It can be found in different countries in North America, Asia, and Europe (among which Italy) [12]. It thrives in beech stumps, withered maple, and other trees [13]. Globally, there are less than 150 known records of this species, and it is not indexed as threatened in the IUCN Red List of Endangered Species.…”

The beech mushroom (Hypsizygus marmoreus) is a highly nutritious, edible medicinal mushroom native to East Asia. The present research investigated the impact of different substrates on the metabolite compositions of H. marmoreus mycelia cultivated in vitro. The substrates tested included malt extract agar, malt extract agar enriched with barley malt, and malt extract agar enriched with grape pomace. The study also assessed antimicrobial and antiradical activities of the extracts against gram-positive bacteria (Bacillus subtilis and Staphylococcus aureus), gram-negative bacteria (Escherichia coli, Salmonella typhi, and Pseudomonas aeruginosa), yeasts (Candida albicans, C. tropicalis, and C. parapsilosis), and dermatophytes (Trichophyton mentagrophytes, T. tonsurans, T. rubrum, Arthroderma quadrifidum, A. gypseum, A. curreyi, and A. insingulare). The results revealed that the H. marmoreus mycelia extracts demonstrated antibacterial and antifungal activities against the tested microorganisms. Extracts obtained from the cultivation in substrates enriched with either barley malt or grape pomace exhibited the highest antibacterial activity among all the tested bacterial strains except for P. aeruginosa. The same extracts showed the highest inhibitory effect against C. albicans and C. parapsilosis. Noteworthy, the extract from the mushroom cultivated in the substrate enriched with grape pomace also exhibited remarkable efficacy against T. mentagrophytes and T. tonsurans. Terpenoid and carbapenem compounds could be related to the antimicrobial properties of the extracts from mushrooms cultivated in substrates enriched with grape pomace. In comparison, the higher antiradical properties could be related to the content of indole compounds. In conclusion, growth substrate selection affects the nutritional and medicinal properties of H. marmoreus, making it a valuable contribution to the understanding of the cultivation of this mushroom.
