A panoramic review of DNA barcoding in microalgae: applications and challenge in the urgency of its use in Peru

Abstract

DNA barcoding is a tool for species identification and classification, overcoming traditional limitations; being fundamental for multiple studies and applications. This article will review the progress of the application of DNA barcoding for algal identification; as it presents advantages such as accuracy in species identification, its applicability to various stages and conditions for ecological studies and intraspecific genetic variability, which according to its approach will depend on several factors. DNA barcoding applications in microalgae, such as its molecular identification, is fundamental for diversity and ecology; expanding knowledge about microalgae; being useful in monitoring harmful algae (HABs) that are a danger to aquatic ecosystems; In addition, DNA barcoding of microalgae is used in biotechnology and food industries. In Peru, taxonomic research is of lesser incidence because there is no method that provides precise identification at the species level, among other reasons, but this DNA barcoding technique has proven to be an efficient tool for research in the conservation and management of organisms that are difficult to access or complex to differentiate, such as microalgae. To conclude, DNA barcoding represents an essential tool in modern microalgae research, which should be developed in Peru, as it has significant potential to advance our knowledge and management of these crucial organisms in Peruvian aquatic ecosystems
