Unraveling the potential of glucosinolates for nutritional enhancement and stress tolerance in Brassica crops

Abstract

Brassicaceae family plants, including cabbage and broccoli, widely distribute glucosinolates derived from amino acids. An S-β-d-glucopyrano unit is anomerically linked to an O-sulfated (Z)-thiohydroximate moiety to form glucosinolates. The potential biological effects of intact glucosinolates are currently being debated within the scientific community. The action of myrosinase on glucosinolate generates glucosinolate-derived hydrolysis products, which increase tolerance to abiotic and biotic stress and improve human health. Here, we investigate the possible applications of glucosinolate bioactive functions, to harness them for the advancement of sustainable agriculture in the future. We have utilized various methods, such as traditional breeding, transgenic techniques, hairy root and plant cell cultures, microbial host-based engineering, and biotechnological methods on Brassica crops to obtain advanced sources of glucosinolates. We can investigate and evaluate the potential for manipulating underutilized or exploited genes related to the biosynthesis, hydrolysis, and transport of glucosinolates, thereby considering them as potential targets for GSL engineering. The goal of this review is to help us learn more about the complicated relationships between glucosinolate-related processes and how they can be used to help plants deal with stress.
