Alteration in the ultrastructural morphology of mycelial hyphae and the dynamics of transcriptional activity of lytic enzyme genes during basidiomycete morphogenesis

© 2017, The Microbiological Society of Korea and Springer-Verlag Berlin Heidelberg.The morphogenesis of macromycetes is a complex multilevel process resulting in a set of molecular-genetic, physiological-biochemical, and morphological-ultrastructural changes in the cells. When the xylotrophic basidiomycetes Lentinus edodes, Grifola frondosa, and Ganoderma lucidum were grown on wood waste as the substrate, the ultrastructural morphology of the mycelial hyphal cell walls differed considerably between mycelium and morphostructures. As the macromycetes passed from vegetative to generative development, the expression of the tyr1, tyr2, chi1, chi2, exg1, exg2, and exg3 genes was activated. These genes encode enzymes such as tyrosinase, chitinase, and glucanase, which play essential roles in cell wall growth and morphogenesis

THE NONSPECIFIC EXTRACELLULAR PEROXIDASES OF PHENOL OXIDASE COMPLEX OF GENUS AZOSPIRILLUM

The screening was conducted by the activity of non-specific extracel­lular lignin peroxidase and manganese peroxidase. Was identify the ability of a num­ber of strains of bacteria of the genus Azospirillum to produce lignin peroxidase and manganese peroxidase. Also was found the ability of a number of strains of bacteria of the genus Azospirillum to oxidation of number of aromatic substrates. Was found the accumulation of the investigated enzymes in the area of the bacterial aggregations on the surface of plant roots
