Editorial: Glucosinolates: Regulation of biosynthesis and hydrolysis

Abstract

The members of the Brassicaceae family possess a class of sulfur and nitrogen containing specialized metabolites glucosinolates (GSLs), that are important for plant defense and animal nutrition. Glucosinolates are both constitutive and inducible, and their accumulation is controlled by environmental, molecular, and genetic levels. Much of the information about the glucosinolate biosynthesis, transport, hydrolysis, turnover, crosstalk amongst biosynthesis and hormonal pathways, and mechanisms controlling glucosinolate accumulation and metabolism during abiotic and biotic stresses has been derived from the model plant Arabidopsis thaliana (Figure 1). However, there are still lacunae in fully understanding these regulatory processes in crop species. Thus, the purpose of this Research Topic is to decipher several aspects under the glucosinolate regulatory mechanisms, in view of which a total of eight research articles have been published.
