Horizontal gene transfer in plants - The story of PgiC2
Sheep's fescue, Festuca ovina, is a common grass found all over Eurasia. In populations in southern Sweden some individuals were found to have two copies of the gene for cytoplasmic phosphoglucose isomerase, PgiC. The second copy, PgiC2, was first believed to be a duplicate of the original gene, PgiC1, but comparisons showed that this is not probable. The PgiC2 locus comprises two PgiC2 genes that
