Identification of a putative P-transporter operon in the genome of a Burkholderia strain living inside the arbuscular mycorrhizal fungus Gigaspora margarita

This article reports the identification of a putative P-transporter operon in the genome of a Burkholderia sp, living in the cytoplasm of the arbuscul ar mycorrhizal fungus Gigaspora margarita. Its presence suggests that Burkh olderia sp, has the potential for P uptake from this environment. This find ing raises new questions concerning the importance of intracellular bacteri a for mycorrhizal symbiosis.
