Fig. 8

Sequence similarity networks (SSN) for LinB. A LinB homologs are depicted in a protein sequence similarity network with an alignment score threshold of 60 (correlating to 35% sequence identity) resulting in a network with distinctly separated clusters corresponding to the different phyla. B LinB homologs are depicted in a protein sequence similarity network with an alignment score threshold of 26 (correlating to 25% sequence identity) and showing the sole, but weak correlation between the nodes of LinB sequences from Kickxellales to nodes of other phyla, especially to Glomeromycotina and plants. Each node represents a member of up to 100 closest LinB orthologs in each phylum or fungal order according to the BLAST search (see Additional file 40: Table S9). Nodes are highlighted in color according to the taxonomic classification. Representative examples including LinB from Linderina pennispora and biochemically verified LinB-like transferases from plants (Avena sativa, Arabidopsis thaliana and Dianthus caryophyllus) are indicated in darker color
