Analyses of the gene expression during mycorrhiza formation have been performed in two species of Agaricales, L. bicolor and H. cylindrosporum (Tables 3 and 4; Additional file 6) [12]. The identification of a group ABCB6 half-size ABC-B transporter and ScYDR061W homologues in L. bicolor experiment is noteworthy, as biological functions of those two groups have not been elucidated in any of the fungal species yet.
