A gene required for di/tripeptide transport in the necrotrophic wheat pathogen Stagonospora nodorum has been cloned, characterised and inactivated by homologous recombination. Recent genome sequencing projects have revealed the presence of fungal homologues though Ptr2 is the first di/tripeptide transporter to be cloned and function characterised from a fungus. Analysis of Ptr2 expression in vitro revealed strong expression in the absence of nitrogen and in the presence of carbon; interestingly...[Show more]
