“…The structure of isothiocyanates is responsible for their efficacy: the more volatile the compound, the greater its antibiological activity due to better distribution. The type of microorganisms being combated, and even the particular phase of their growth, is also important [25]. The mode of action behind AITC's antimicrobial activity is not yet fully understood, but since it might penetrate membranes and no single site of action has been described, it is generally regarded as a non-specific inhibitor of periplasmic or intracellular targets.…”

Recently there has been a renewed interest in improving health and fitness through the use of more natural products. Herbs and spices have been used for thousands of years to enhance the flavor, color and aroma of food, also known for their preservative and medicinal value. Recent reports suggest that cruciferous vegetables act as a good source of natural antioxidants due to the high levels of carotenoids, tocopherols and ascorbic acid. In addition to carotenoids, tocopherols, and ascorbic acid, most of the antioxidative effect related to plant food intake is mainly due to the presence of phenolic compounds, which have been associated with flavour and colour characteristics of fruits and vegetables. In this aspect, the popularity and consumption of vegetable Brassica species is increasing because of their nutritional value. Brassica foods are very nutritive, providing nutrients and healthpromoting Phytochemicals such as vitamins, carotenoids, fiber, soluble sugars, minerals, glucosinolates and phenolic compounds [1]. Brassica is one of the most ancient spices. It has 3 varieties namely black, brown and white/yellow. Brassica juncea (Brown mustard) is largely cultivated. Brown mustard plant produces tiny yellow colored flowers, which almost cover the plant. The plant is extensively grown for its mustard and as fodder crop. In addition, this species is known to be of great medicinal importance due to its antineoplastic, antimicrobial, and insecticidal activities. The plant is a folk remedy for arthritis, foot ache, lumbago, and rheumatism. Sinapis alba is an economically important plant of Brassicaceae, commonly known as yellow or white mustard, and growing well in hot and dry environments [2]. However, there is limited published research on essential oil composition and activity of both species in spite of the historical and traditional knowledge of both oils' medicinal importance. The popularity and consumption of vegetable Brassica species is increasing because of their nutritional value. Brassica crops have been related to the reduction of the risk of chronic diseases including cardiovascular diseases and cancer. Brassica foods are very nutritive, providing nutrients and health-promoting Phytochemicals such as vitamins, carotenoids, fiber, soluble sugars, minerals, glucosinolates and phenolic compounds [3]. Materials and MethodsBrown and yellow mustard seeds were purchased from local market of Gorakhpur. The fresh and mature berries of B.juncea and S.alba were washed; sun dried and pulverized into a fine AbstractMany consumers are demanding foods without what they perceive as artificial and harmful chemicals, including many used as antimicrobials and preservatives in food. Consequently, interest in more natural, antimicrobials as potential alternatives to conventional additives to extend shelf life and combat foodborne pathogens has heightened. In the present study, phytochemical, in vitro antioxidant and antimicrobial potentials of essential oils and oleoresins of Brassica juncea and Sinapis Alba seeds were ...

“…Several approaches, such as the use of pathogen-suppressive soils, organic amendments, and biological fumigation, have identified potentially useful mechanisms that can be exploited through plant breeding. Glucosinolate, which is produced by canola and decomposes in soil to produce compounds found in commercial soil fumigants effective against soil-borne pathogens, is an example (Gimsing and Kirkegaard 2009). Breeding can increase root exudation and rhizodeposition to selectively enrich species and communities of pathogen-suppressive microbes or better fortify roots to stop or reduce infection.…”

Abstract. Climate change in Australia is expected to influence crop growing conditions through direct increases in elevated carbon dioxide (CO 2 ) and average temperature, and through increases in the variability of climate, with potential to increase the occurrence of abiotic stresses such as heat, drought, waterlogging, and salinity. Associated effects of climate change and higher CO 2 concentrations include impacts on the water-use efficiency of dryland and irrigated crop production, and potential effects on biosecurity, production, and quality of product via impacts on endemic and introduced pests and diseases, and tolerance to these challenges. Direct adaptation to these changes can occur through changes in crop, farm, and value-chain management and via economically driven, geographic shifts where different production systems operate. Within specific crops, a longer term adaptation is the breeding of new varieties that have an improved performance in 'future' growing conditions compared with existing varieties.In crops, breeding is an appropriate adaptation response where it complements management changes, or when the required management changes are too expensive or impractical. Breeding requires the assessment of genetic diversity for adaptation, and the selection and recombining of genetic resources into new varieties for production systems for projected future climate and atmospheric conditions. As in the past, an essential priority entering into a 'climate-changed' era will be breeding for resistance or tolerance to the effects of existing and new pests and diseases. Hence, research on the potential incidence and intensity of biotic stresses, and the opportunities for breeding solutions, is essential to prioritise investment, as the consequences could be catastrophic. The values of breeding activities to adapt to the five major abiotic effects of climate change (heat, drought, waterlogging, salinity, and elevated CO 2 ) are more difficult to rank, and vary with species and production area, with impacts on both yield and quality of product. Although there is a high likelihood of future increases in atmospheric CO 2 concentrations and temperatures across Australia, there is uncertainty about the direction and magnitude of rainfall change, particularly in the northern farming regions. Consequently, the clearest opportunities for 'in-situ' genetic gains for abiotic stresses are in developing better adaptation to higher temperatures (e.g. control of phenological stage durations, and tolerance to stress) and, for C 3 species, in exploiting the (relatively small) fertilisation effects of elevated CO 2 . For most cultivated plant species, it remains to be demonstrated how much genetic variation exists for these traits and what value can be delivered via commercial varieties. Biotechnology-based breeding technologies (marker-assisted breeding and genetic modification) will be essential to accelerate genetic gain, but their application requires additional investment in the understanding, genetic characterisation,...

“…1. Highest glucosinolate content was found in the WIN leaf material, followed by PSB and SAV during optimal biofumigation practices (maximum tissue disruption and water addition) up to 100 nmol ITC per gram soil can be released in the soil, while a release efficacy of approximately 60 % could be measured under field conditions (Gimsing and Kirkegaard 2009). In our study, the amounts potentially released were estimated to reach 88 nmol 3-butenyl ITC (derived from gluconapin, 3-butenyl GSL) per gram of soil (calculated via 1 % DW plant material compared to DW soil, with an average of 14.65 μmol gluconapin per gram of DW plant material and assuming the same conversion efficiency).…”

“…One percent of freeze-dried leaf material relative to total soil (on a dry weight (DW)/DW base) was used for biofumigation. Leaf material was completely fragmented using a laboratory blender (IKA, A11 basic) to ensure maximum tissue rupture and, in turn, GSL release efficiency and hydrolysis potential (Gimsing and Kirkegaard 2009).…”
