Identification and phylogenetic analysis of the genus Syringa based on chloroplast genomic DNA barcoding

PLoS ONE, 2022
DNA barcoding is a supplementary tool in plant systematics that is extensively used to resolve species-level controversies. This study assesses the significance of using two DNA barcoding loci (e.g., psbA-trnH and trnC-petN) in distinguishing 33 plant ...
