Видовое разнообразие и генетический полиморфизм энтомопатогенных грибов рода Lecanicillium

Abstract

Among 43 strains of entomopathogenic fungi Lecanicillium muscarium there were evaluated the relationships between morphological and biochemical parameters and molecular characteristics (the haplotypes of the mitochondrial gene nad1). The correlation coefficients between the molecular haplotype and the degree of the development of an aerial mycelium and spore sizes were low: 0.34 and –0.23, respectively. It was found the higher correlations for some morphological and biochemical parameters: between the degree of development of aerial mycelium and the growth rate (0.43) and antibiotic activity of cultural filtrate (0.4); between the fungicidal activity of the cultural filtrate and the amount of conidia (0.4); between the antibacterial activity of the cultural filtrate and the insecticidal activity of the extract from fungal mycelium (–0.39). To identify the closer connections it is necessary to search the more sensitive molecular markers and other significant morphological and biochemical parameters.
