In some cruciferous plants, epithiospecifier protein (ESP) directs myrosinase (EC 3.2.3.1)-catalyzed hydrolysis of alkenyl glucosinolates toward epithionitrile formation. Here, for the first time, we show that ESP activity is negatively correlated with the extent of formation of the health-promoting

Seeds of 32 pure lines and six commercial broccoli cultivars were used to investigate variation in glucosinolates and their breakdown products. Aliphatic glucosinolate content was 54.5-218.7 μmol/g fresh weight, accounting for > 90 % of the total glucosinolates. The major glucosinolates found
