Stress in plant and their benefits for the secondary compound accumulation: a review

In recent years, crops have often experienced an increasing number of abiotic and biotic stresses, which significantly impair their growth and output due to global warming and accompanying climatic irregularities. Many studies have been carried out to improve plants' stress tolerance, including using fertilizers, microbial interactions, plant growth regulator application, and other methods. However, stress's role in improving a plant's ability to create a variety of secondary compounds such as phenolic acid, flavonoids, and anthocyanins, some of which have been linked to antioxidant activity and positive impacts on health, has yet to be well investigated. This review aims to summarize the potential for stress concerning the use of secondary compound content in plants.
