Plant DNA barcoding research is shifting beyond performance comparisons of different DNA regions towards practical applications. The main aim of DNA barcoding is to establish a shared community resource of DNA sequences that can be used for organismal identification and taxonomic clarification. This approach was successfully pioneered in animals using a portion of the cytochrome oxidase 1(CO1) mitochondrial gene. In plants, establishing a standardized DNA barcoding system has been more challenging. The studies on cucumis sp for the application of DNA barcode shows the possibility of discrimination at species level not the varietal level using the matK gene barcode. The phylogenetic tree constructed by using matK gene sequences clearly differentiated the species C. sativus and C. melo which will help for the future application in cucumis taxonomy and phylogeny studies
