BACKGROUND Molecular farming is the production of important recombinant proteins in transgenic organisms on an agricultural scale. Interferons are proteins with antiviral and antitumor activities and can be used for viral infections and cancers treatments. OBJECTIVES This study reports the transformation of INF α2b gene in tobacco plant for the first time in Iran. MATERIALS AND METHODS Inte...

Transition from vegetative cells to aerial mycelium and spores of Streptomyces collinus is accompanied by changes in the pattern of proteins phosphorylated. Preparation from spores exhibits lower phosphorylation activity than those of vegetative cells and aerial mycelium. Phosphorylation of proteins from aerial mycelium was markedly stimulated by the presence of Mn2+. Our data indicate that pho...

Aspergillus flavus produces a lipase (EC 3.1.1.3) which is partly bound to the mycelium during growth. The production of the mycelium-bound lipase is concomitant with growth, and declines when growth ceases. Maximum productivity of the enzyme is obtained when the culture is incubated at 30°C, an initial culture pH of 6·5 and with 2% (w/v) each of corn oil and yeast extract as carbon and organic...

Plant cover loss due to changes in land use promotes a decrease in spore diversity of arbuscular mycorrhizal fungi (AMF), viable mycelium and, therefore, in AMF colonization, this has an influence in community diversity and, as a consequence, in its recovery. To evaluate different AMF propagules, nine plots in a tropical dry forest with secondary vegetation were selected: 0, 1, 7, 10, 14, 18, 2...

Background: Agaricus bisporus is an edible basidiomycete fungus. Both the body and the mycelium contain compounds comprising a wide range of antimicrobial molecules, contributing in improvement of immunity and tumor-retardation. Objectives: The presence of endophytes capable of producing bioactive compounds was investigated in Agaricus bisporus. Materials and Methods: Endophytes from Agaricus b...
