“…Aliphatic glucosinolates can undergo various modifications, such as alkenylations, oxidations, benzoylations, and hydroxylations. Indolic glucosinolates are mainly subjected to methoxylations and hydroxylations [105,106]. These modifications occur in an organ and development-specific pattern [107,108].…”

The ability of plants to release chemicals that affect the growth of other plants offers potential benefits for weed management and sustainable agriculture. This review explores the use of Camelina sativa as a promising cover crop with weed control potential. Camelina sativa, known for its high oil content and adaptability to diverse climatic conditions, exhibits allelopathic potential by releasing chemical compounds that inhibit weed growth. The crop’s vigorous growth and canopy architecture contribute to effective weed suppression, reducing the prevalence and spread of associated pathogens. Furthermore, the chemical compounds released by camelina through the solubilization of compounds from leaves by rain, root exudation, or deriving from microbial-mediated decay of camelina’s tissues interfere with the growth of neighbouring plants, indicating allelopathic interactions. The isolation and identification of benzylamine and glucosinolates as allelochemicals in camelina highlight their role in plant–plant interactions. However, the studies carried out on this species are outdated, and it cannot be excluded that other chemicals deriving from the breakdown of the glucosinolates or belonging to other classes of specialized metabolites can be involved in its allelopathic potential. Camelina sativa also demonstrates disease suppression capabilities, with glucosinolates exhibiting fungicidal, nematocidal, and bactericidal activities. Additionally, camelina cover crops have been found to reduce root diseases and enhance growth and yields in corn and soybeans. This review sheds light on the allelopathic and agronomic benefits of Camelina sativa, emphasizing its potential as a sustainable and integrated pest management strategy in agriculture.

“…Effect of CHEW on the expressions of genes related to glucosinolates metabolism Molecular mechanism of aliphatic glucosinolates biosynthesis has been elucidated, mainly including the following three stages: (1) extension of the methionine side chain; (2) formation of the glucosinolate core structure; (3) dimeric glucosinolate side chain secondary modi cation 23,24 . Elong and BCAT4 are the main genes involved in the rst stage.…”

Background Electrolyzed water, an invention of green chemistry, is a novel disinfectant that has been widely used in the food field. Previous studies have found that slightly acidic electrolyzed water not only has a bactericidal effect, but also promotes the accumulation of active substances in many types of sprouts. We have developed a new type of electrolyzed water - CaCl2-HCl electrolyzed water (CHEW), which is an effective method to enhance the formation of glucosinolates and isothiocyanates of broccoli sprouts. Molecular mechanism of CaCl2-HCl electrolyzed water promoting glucosinolate metabolism in broccoli sprout during the growth was investigated in this study. Results On the 4th day, the total glucosinolates’ content of broccoli sprouts reached 195.50 µmol/g DW under CHEW treatment. On the 8th day, compared to tap water, the contents of 3 isothiocyanates (sulforaphane, erucin, 4-isothiocyanato-1-buene) in broccoli sprouts under CHEW treatment were significantly increased by 45.93%, 34.04% and 185.15% respectively. The results of calcium distribution and RT-qPCR indicated that CHEW treatment activated calcium signal in broccoli sprouts and promoted the relative expressions of glucosinolate biosynthesis-related genes through calcium sensors (calmodulin (CaM), calmodulin-like protein (CML), calcium-dependent protein kinase (CDPK)) and calcium-binding nuclear protein IQD1. Conclusion Our research provides new insights into the molecular mechanism of glucosinolate metabolism and also provided a theoretical basis for cultivating high-quality broccoli sprouts.

“…The biosynthesis of glucosinolate in broccoli sprouts has been clarified, which mainly includes three stages: (a) side-chain elongation of amino acid; (b) formation of glucosinolate core structure; (c) secondary modification of glucosinolate side chain [11]. The formation of the glucosinolate core structure is not only a common part of all glucosinolates, but also a key step in glucosinolate synthesis.…”

Glucosinolates are important phytochemicals in Brassicaceae. We investigated the effect of CaCl 2 -HCl electrolyzed water (CHEW) on glucosinolates biosynthesis in broccoli sprouts. The results showed that CHEW treatment significantly decreased reactive oxygen species (ROS) and malondialdehyde (MDA) contents in broccoli sprouts. On the the eighth day, compared to tap water treatment, the the total glucosinolate content of broccoli sprouts with CHEW treatment increased by 10.6% and calcium content was dramatically enhanced from 14.4 to 22.7 mg/g DW. Comparative transcriptome and metabolome analyses revealed that CHEW treatment activated ROS and calcium signaling transduction pathways in broccoli sprouts and they interacted through MAPK cascades. Besides, CHEW treatment not only promoted the biosynthesis of amino acids, but also enhanced the expression of structural genes in glucosinolate synthesis through transcription factors (MYBs, bHLHs, WRKYs, etc.). The results of this study provided new insights into the regulatory network of glucosinolates biosynthesis in broccoli sprouts under CHEW treatment.
