Although DNA-based analytical methods had been around for a while, it wasn't until 2003 that the term "DNA barcoding" became popular. The research-analytical and application paradigms have continued to develop and diversify since then. Initially, it was only applicable to the animal kingdom and later the method was modified by scientists studying plant biology tailoring it to fit the needs. This document provides a meta-analysis of DNA barcoding research trends, specifically in plant sciences, examining its methodological advancements, application diversity and evolving research themes. By classifying and analyzing the current data trends, we offer insights into the ongoing transformations of DNA barcoding. Furthermore, actionable recommendations for future research are proposed, including the development of more reliable, cost-effective markers and exploring ecological and biodiversity applications. This analysis serves as a guide for both novice and experienced researchers to navigate the rapidly advancing field of DNA barcoding.
