Summary
Lippia (Phyla canescens: Verbenaceae) is a serious weed of wetlands, riparian zones and floodplains, particularly in eastern Australia where many Ramsar wetlands are threatened by hydrological changes precipitated by soil accreting lippia mats. Understanding the genetic structure of lippia population is crucial in finding and developing bio-control agents. Microsatellite markers were developed for Phyla canescens. Genetic structures of Australia populations of lippia were compared to that of native range. ITS sequences analyses revealed that Australian populations of lippia have originated from at least two regions in Argentina. Considerable advances have been made in our genetic understanding of this species, which will have an important influence in its management and control. Low levels of diversity have been detected in 15 populations of lippia in Australia. In addition Genetics and genomics show that there is minimal genetic exchange occurring among these populations .
