“…Currently, the mitochondrial gene cytochrome oxidase I ( COI ) has been proven to be an ideal DNA barcode for animals (Burns et al, 2008; Kerr et al, 2007; Kim et al, 2012), whereas this DNA region is not suitable for plant identification due to the low substitution rates of plant mitochondrial DNA (Cho et al, 2004; Duminil, 2014; Kress et al, 2005). Alternatively, plastid sequences ( rbcL and matK ) and the internal transcribed spacer (ITS) of nuclear ribosomal DNA (nrDNA) have been recommended as core barcodes for plants, and plastid sequences ( trnH‐psbA and trnL ‐F) have been recommended as supplementary barcodes (CBOL Plant Working Group, 2009; Chase et al, 2007; Hollingsworth et al, 2011; Hu et al, 2022; Kress et al, 2009; Lahaye et al, 2008; Li et al, 2009; Li, Gao, et al, 2011; Li, Liu, et al, 2011; Tonti‐Filippini et al, 2017; Vijayan et al, 2009; Worthy et al, 2022). The application of DNA barcoding has been successfully used in the problem of species identification in a large number of taxa (e.g., Giudicelli et al, 2015; Gogoi & Bhau, 2018; Liu et al, 2011, 2018).…”
