“…Furthermore, the highest GLS concentration was observed in the second development stage (42 days after transplanting (DAT)) during poor sulphur fertilisation and in the third stage (49 DAT) during rich sulphur fertilisation, after which GLS concentration decreased until the overmaturity stage [41]. In contrast, in broccoli, the degradation product of the GLS glucoraphanin, sulphoraphane (SFN), increased until the commercial maturity stage [42] and the highest content of glucoraphanin occurred at the mature head stage and then declined as flowering was initiated [43]. Finally, in potherb mustard, sinigrin concentration decreased from seedling to early flowering stage, increased in the late flowering stage and then decreased again during seed maturation [43].…”

Glucosinolates (GLSs) are found in Brassica vegetables. Examples of these sources include cabbage, Brussels sprouts, broccoli, cauliflower and various root vegetables (e.g. radish and turnip). A number of epidemiological studies have identified an inverse association between consumption of these vegetables and the risk of colon and rectal cancer. Animal studies have shown changes in enzyme activities and DNA damage resulting from consumption of Brassica vegetables or isothiocyanates, the breakdown products (BDP) of GLSs in the body. Mechanistic studies have begun to identify the ways in which the compounds may exert their protective action but the relevance of these studies to protective effects in the human alimentary tract is as yet unproven. In vitro studies with a number of specific isothiocyanates have suggested mechanisms that might be the basis of their chemoprotective effects. The concentration and composition of the GLSs in different plants, but also within a plant (e.g. in the seeds, roots or leaves), can vary greatly and also changes during plant development. Furthermore, the effects of various factors in the supply chain of Brassica vegetables including breeding, cultivation, storage and processing on intake and bioavailability of GLSs are extensively discussed in this paper.

“…The content and composition of glucosinolates varies depending on Brassica species, the cultivar plant parts within the same plant, agronomic practices and climatic conditions (Sang et al, 1984;Clossais-Bernard and Larher, 1991;Rangkadilok et al, 2002;Font et al, 2005;Tripathi and Mishra, 2007). Glucosinolates are known to mediate interactions between Brassicaceae and their associated insect herbivores.…”

-Brassica crops are grown worldwide for oil, food and feed purposes, and constitute a significant economic value due to their nutritional, medicinal, bioindustrial, biocontrol and crop rotation properties. Insect pests cause enormous yield and economic losses in Brassica crop production every year, and are a threat to global agriculture. In order to overcome these insect pests, Brassica species themselves use multiple defence mechanisms, which can be constitutive, inducible, induced, direct or indirect depending upon the insect or the degree of insect attack. Firstly, we give an overview of different Brassica species with the main focus on cultivated brassicas. Secondly, we describe insect pests that attack brassicas. Thirdly, we address multiple defence mechanisms, with the main focus on phytoalexins, sulphur, glucosinolates, the glucosinolate-myrosinase system and their breakdown products. In order to develop pest control strategies, it is important to study the chemical ecology, and insect behaviour. We review studies on oviposition regulation, multitrophic interactions involving feeding and host selection behaviour of parasitoids and predators of herbivores on brassicas. Regarding oviposition and trophic interactions, we outline insect oviposition behaviour, the importance of chemical stimulation, oviposition-deterring pheromones, glucosinolates, isothiocyanates, nitriles, and phytoalexins and their importance towards pest management. Finally, we review brassicas as cover and trap crops, and as biocontrol, biofumigant and biocidal agents against insects and pathogens. Again, we emphasise glucosinolates, their breakdown products, and plant volatile compounds as key components in these processes, which have been considered beneficial in the past and hold great prospects for the future with respect to an integrated pest management.Brassicas / insect pests / chemical ecology / trophic levels / glucosinolates / isothiocyanates / defence mechanisms / biocontrol / trap crops / integrated pest management

“…Within different forms of B. oleracea, 12 different glucosinolates have been detected. The beneficial glucosinolate glucoraphanin showed significant variation ranging from 44 to 274 µmole/g seed in different genotypes of broccoli Rangkadilok et al, 2002). Furthermore, variation in concentration of individual glucosinolates also exists in cultivars of the same species.…”
