Glucosinolates and Its Role in Mitigating Abiotic and Biotic Stress in Brassicaceae

Abstract

Abiotic stresses such as increase in daily mean temperature, changed patterns of precipitation, increase in episodes of drought and floods in future are faced by the plants and pose threats to crop production and food security. Induction of secondary metabolites by several abiotic stress conditions can be helpful in the crop protection against biotic stress and can be a major link between biotic and biotic stress. Plants also face threats by injury caused by herbivores and insects that chew on plants. Plant develops, coordinates and combines defence mechanism to cope with the challenges caused by the injuries. The plant family Brassicaceae (or Cruciferae) includes some of the world’s most economically important crops; especially members of the genera Brassica L. Brassicaceae vegetables are a good source of secondary metabolite that is Glucosinolates. Which are responsible for characteristic flavour and odour, when degraded. Glucosinolates and their degradation products play important roles in stress tolerance, plants respond to abiotic and abiotic stress by systematically accumulating higher levels primary and secondary metabolites for increasing their resistance. Glucosinolates play important role and have a relation with biotic and abiotic stress in Brassica plant family, as they can act as a signalling molecules and affect the physiology of plant.

De Novo Transcriptome Assembly, Gene Annotations, and Characterization of Functional Profiling Reveal Key Genes for Lead Alleviation in the Pb Hyperaccumulator Greek Mustard (Hirschfeldia incana L.)

“…Several genes involved in regulation, biosynthesis, and transport of glucosinolates such as SOT18 (sulfotransferase), GTR1 (major facilitator superfamily protein), APK2 (adenylyl-sulfate kinase 2), JAL23 , BASS5 , BGLU32 (beta-glucosidase 32), and IGMT5 in aboveground parts and SDI1 (sulphur deficiency-induced 1) in roots were upregulated in H. incana in response to Pb stress. Our finding is in accordance with several reports mentioning that under Zn, Cd, and Pb the biosynthesis of glucosinolates was higher in other Brassica species [ 54 , 55 ]. These authors suggest that glucosinolates play an important role in heavy-metal tolerance in different Brassica plant species [ 54 , 55 ].…”

Concurrent anthropogenic air pollutants enhance recruitment of a specialist parasitoid

“…The combined pollution treatment significantly increased plant glucosinolate concentrations, especially of the aliphatic glucosinolate gluconapin (3-butenyl-glucosinolate). These changes in leaf tissue concentrations suggest that the plants modified their glucosinolate production as a stress-induced response to their exposure to both pollutants simultaneously [47,48]. Increases in concentrations of gluconapin were positively correlated with increases in abundance of D. rapae .…”

Enriched‐biochar application increases broccoli nutritional and phytochemical content without detrimental effect on yield

“…GSLs and their degradation products play important roles in abiotic and biotic stress tolerance, playing an important role as signalling molecules and affecting plant physiology. 33 S fertilization and its interaction with N fertilization have been reported to play an important role in GSL concentration in brassica vegetables. Rather than only S or N fertilization, 34 a negative linear relationship has been observed between total GSL concentration and the N/S ratio in the leaves of two brassica cultivars.…”
