Molecular systematics and species concept in fungi: approaches and resolutions
A review paper presents some data on phylogenetic analysis in fungi. The paper is focused on methods and approaches, molecular characters and specific sequences more frequently employed. Advantages of conservative and variable sequences of the ribosomal genes cluster and other functional genes are under discussion. Morphological, biological and molecular species concepts are also presented. Two different molecular approaches for the phylogenetic reconstruction - distance methods and discrete-character methods - are discussed. The paper also presents in detail a procedure for phylogenetic reconstruction and tree drawing.
