Trehalose degradation. a Distinct putative pathways for trehalose transport, phosphorylation and hydrolysis. Pi: inorganic phosphate; PEP: phosphoenolpyruvate; A and IIBC: elements of the PTS permease; Mfs and ABC: sugar transporters. b Genes associated with the putative pathways. The genes encoding the general PTS protein (EI and Hpr) of O. oeni have been described by Jamal et al. [22]. c Genotype/phenotype correlations. Strains appear in the same order as on the phylogenomic dendrogram (Additional file 2: Figure S2). In the lane phenotypes, the blue boxes indicate the strains able to grow on trehalose as the sole carbon source, and the red ones indicate the strains unable to grow in such conditions. In the lanes for genotypes, a red box indicates that the gene or one of the genes in the operon is truncated or appears as a pseudogene. The green color indicates no gene truncation but mutations still can lead to inactive proteins. The orange box indicates that the corresponding genome sequence displays a specific mutation leading to a singular protein (i.e., EI is singular in O. oeni IOEB 0607). As the genes encoding Hpr and β-PGM are highly conserved, they do not appear in this table
