Proteinases in fungal morphogenesis

Abstract

Fungal morphogenesis is a regulated series of events, leading to changes from one state to another, in which proteolysis could be regarded as one of the controlling functions. Proteinases are essential for the supply of amino acids, selective inactivation of specific growth phase proteins not required during development and for the activation and modification of the enzymes involved in cell wall synthesis. A critical evaluation of the role of proteinases as a biochemical correlate in fungal morphogenesis is discussed.

Mycelial growth of strains of Pleurotus ostreatus developed on agar and its correlation with the productivity in pilot production farm

“…In the same row, results with the same letter are not significantly different (p < 0.001); 1 Period of time in which the fruit bodies were observed (expressed in days); 2 Day in which the mushroom was harvested; 3 Average daily mushroom production in kg of fresh mushroom per kg of dry wheat straw.…”

“…It has been reported that in Agaricus bisporus and Lentinula edodes, the production of laccases increased as the mycelium developed and decreased at the beginning of the fructification, suggesting that laccases are primarily active during substrate colonization (9). The 3 14 c ± 2 17 b ± 2 14 c ± 1 14 c ± 3 21 a ± 4…”

Biotechnological Applications of Dimorphic Yeasts

“…In most of the dimorphic yeasts, the physiological make up of both the forms is different which plays an important role in the life cycle of the organisms and in turn can be used for the distinct applications (Deshpande, 1992(Deshpande, , 1996. The form-specific expression of certain proteins has also been reported.…”

“…Serine proteases and acid proteases are produced by most of the fungi, whereas cysteine proteases and metal proteases are more limited. Proteases play major part in the growth and differentiation of fungi (Deshpande, 1992 ). Proteases are also of great commercial value in detergents, leather and food industries (Rao et al, 1998 ).…”

Characterization of the Solid-State and Liquid Fermentation for the Production of Laccases of Pleurotus ostreatus

“…The growth of all parts of a fungus occurs at the hyphal tips. The mycelial structure grows by synthesizing new wall at the hyphal apex, as they increase in length, additional sites for wall synthesis are formed in the subapical region, originating lateral branches that synthetize wall again confined to the hyphal tip [11]. The formation of a new branch requires the production of a new apex from the existing mature hyphal cell.…”
