To identify the origins of C upriavidus nodule symbionts associated with two invasive M imosa species in the P hilippines, 22 isolates were sequenced for portions of three chromosomal genes and two symbiotic plasmid loci. Eleven isolates were identical at all gene loci (2713 bp) to a lineage found in C entral A merica. Four other P hilippine isolates were identical to a second C upriavidus lineage distributed both in C entral A merica and in the C aribbean. None of the remaining P hilippine strains had more than 0.6% sequence divergence from A merican C upriavidus lineages. These results imply that the P hilippine population was founded by multiple introductions from the native range of their M imosa hosts.
