  1. 16. Alternative oxidase respiration in the mycorrhizal fungus Laccaria bicolor

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Hilda Mikaelsson; [2019]
    Keywords : L. bicolor; mycel; ektomykorrhiza; cellandning; AOX; alternativt oxidas; cytokromoxidas; cyanid; mycelium; ectomychorriza; respiration; alternative oxidase; cytochrome oxidase; salicylhydroxamic acid; n-propyl gallate; cyanide;

    Abstract : The temperature on Earth is rising, and one of the main drivers is anthropogen-ic greenhouse gases such as carbon dioxide (CO2). The world’s forests act as carbon sinks, binding carbon into their biomass. The net carbon assimilation is determined by the uptake and release of CO2 through the processes of photo-synthesis and respiration. READ MORE
