Structural features of the aromatic/arginine constriction in the aquaglyceroporin GintAQPF2 are responsible for glycerol impermeability in arbuscular mycorrhizal symbiosis
The aquaglyceroporin GintAQPF2 from AM fungi disfavoured glycerol transport. Genomes of four representative fungi with different lifestyles were compared. A conserved pattern of glycerol transport in symbionts and pathogens was revealed. Blocked glycerol passage could be involved in the establishment of obligate biotrophy of AM fungi.
