Plant Phenolics in Abiotic Stress Management

Abstract

Among the different types of abiotic stress, one of the most important is irradiation stress. Ultraviolet (UV) irradiation represents between 7 and 9% of total solar radiation, and and is composed between 100 and 400 nm of the electromagnetic spectrum. It is mainly divided into UV-A (315–400 nm), UV-B (280–320 nm), and UV-C (200–280 nm). This type of irradiation can affect DNA, proteins, and plant cells. This could affect the development, morphology, and photosynthesis. To counteract these harmful effects, plants use their defense mechanisms, mainly the production of secondary metabolites, among which phenolic compounds stand out (phenolic acids, flavonoids, stilbenes, tannins, lignins, and coumarins). These are of great interest for its antioxidant, anticancer, antimicrobial properties, among others. However, the responses in the increase of the different phenolic compounds will depend on factors such as intensity, type of UV light and exposure time, which is reflected in the different investigations carried out on this topic. In this sense, it is interesting to review the variety of phenolic compounds that have been reported through induction by UV irradiation.
