Glucosinolates are the biochemical compounds that provide defense to plants against pathogens and herbivores. In this study, the relative expression level of 48 glucosinolate biosynthesis genes was explored in four morphologically-different cabbage inbred lines by qPCR analysis. The content of aliphatic and indolic glucosinolate molecules present in those cabbage lines was also estimated by HPL...

Blackleg, a fungal disease caused by Leptosphaeria maculans, is one of the most devastating diseases of Brassica crops worldwide. Despite notable progress elucidating the roles of glucosinolates in pathogen defense, the complex interaction between B. oleracea (cabbage) and L. maculans infection that leads to the selective induction of genes involved in glucosinolate production and subsequent mo...

Chinese kale, a vegetable of the cruciferous family, is a popular crop in southern China and Southeast Asia due to its high glucosinolate content and nutritional qualities. However, there is little research on the molecular genetics and genes involved in glucosinolate metabolism and its regulation in Chinese kale. In this study, we sequenced and characterized the transcriptomes and expression p...

Seven groups of 10 growing rats each were fed a control diet or rapeseed diets with glucosinolate contents ranging from 4.4 to 36.6 mM/kg DM. After a 5-day adaptation period, the rats were fed ad libitum for 17 days. The food intake of the experimental groups was maximal after 11 days and was, on an average, 4 to 45% lower than that of the control group. The differences were still greater durin...

in order to compare yield and agronomic characteristics of 38 new winter rapessed (brassica napus l.) cultivars along with okapi as check, a field experiment was carried out based on randomized complete block design during 2009-10 cropping season with three. rapeseed cultivars showed significant differences for all traits at 1 percent probability level. in this research, es betty, nk karibik, n...

It is widely accepted that the distinctive aroma and flavour traits of Brassicaceae crops are produced by glucosinolate (GSL) hydrolysis products (GHPs) with other non-GSL derived compounds also reported to contribute significantly their aromas. This study investigated profile content four species (salad rocket, horseradish, wasabi, watercress). Solid-phase microextraction followed gas chromato...

Glucosinolates are natural plant products that function in the defense toward herbivores and pathogens. Plant defense is regulated by multiple signal transduction pathways in which salicylic acid (SA), jasmonic acid, and ethylene function as signaling molecules. Glucosinolate content was analyzed in Arabidopsis wild-type plants in response to single or combinatorial treatments with methyljasmon...

Models predicting optimal levels of plant defense against herbivores typically include two assumptions: 1) defense is both beneficial and costly; and 2) the relationship between costs and benefits of a defense is consistent across environments. However, the expression of costs and benefits of defense may be environmentally dependent. We examined lines of Brassica rapa, previously divergently se...
