Researchers Trace Gene Flow Using Microsatellites
December 12, 2012| |
A new technique was developed by scientists from the University College of London, which could help in understanding gene migration in evolutionary biology. The research team identified the segregation of genes that the marine plant Cymodocea nodosa went through during its evolution. They used molecular markers to retrace the plant's gene flow, using populations from different geographical locations. They aimed to deduce the evolutionary pathways from datasets gathered from sequencing the plant, made portions of non-coding DNA called microsattelites. Through this new method, Paolo Masucci and colleagues found that gene flow most probably happened westward from the Mediterranean to the Atlantic. This as further confirmed by natural evidence and results of independent cross analysis.
