Calcium in fungi

Abstract

Abstract. Recently much experimental evidence has accumulated concerning intracellular calcium and its fundamental role as a regulator in eukaryotic cells. The literature relating to Ca 2+ in fungi is large and diverse and this paper draws together the available information and discusses the particular functions of the ion in this group of organisms. Uptake mechanisms in fungi are considered with special reference to the effect of Ca 2+ on permeability and the systems responsible for transport of ions, sugars and amino acids. Discussion of the subcellular locations and distribution of Ca 2+ is accompanied by a critique of methodology used in determination of subcellular sites of Ca 2+ in fungi. The role of Ca 2+ in morphogenesis in fungi is considered with particular reference to selected groups.
