- Premise of the study: New primers were developed for the nuclear marker glutamine synthetase (ncpGS) in Oxalidaceae. METHODS: and Results: New forward and reverse primers were designed and tested across a wide range of Oxalidaceae. Selected taxa were sequenced to confirm homology. Potential for phylogenetic study was assessed by comparing sequenced taxa with commonly used nuclear and plastid markers. CONCLUSIONS: Four out of five Oxalidaceae genera and all tested Oxalis spp. amplified successfully. Sequencing confirmed homology of the amplicon. Parsimony analysis of ncpGS showed that it is a promising candidate for future phylogenetic work in Oxalidaceae.
