rbcLmatK
rbcLmatK refers to the combined chloroplast DNA barcode regions rbcL and matK, commonly used in plant identification and phylogenetics. The rbcL gene encodes the large subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase and is part of the chloroplast genome. MatK encodes maturase K and resides within the intron of the trnK gene in the chloroplast genome. Together, these regions provide complementary information for species discrimination and phylogenetic analysis.
Rationale and use. rbcL is highly conserved and generally easy to amplify and align across broad plant
Methodological notes. Universal primers have been developed for both loci, enabling broad applicability across plant taxa.
Applications and data resources. rbcLmatK data underpin plant biodiversity surveys, systematics studies, and barcode-based identifications in
