Variation of glucosinolates in vegetable crops of Brassica rapa L. ssp. pekinensis

Variation in glucosinolates in pak choi cultivars and various organs at different stages of vegetative growth during the harvest period

“…1). This genotypic variation in GS content in the pak choi cultivars is consistent with previous studies (He et al, 2000;Castro et al, 2004;Kim et al, 2010). The variation in GS content among the pak choi cultivars may be due to differences in their genetic backgrounds or developmental and environmental regulation (Rosa et al, 1996;Petersen et al, 2002;Brown et al, 2003;Bellostas et al, 2004;Velasco et al, 2007).…”

Identification and quantification of glucosinolates in Korean leaf mustard germplasm (Brassica juncea var. integrifolia) by liquid chromatography–electrospray ionization/tandem mass spectrometry

“…1.3-8.8 mg/g DW) for B. campestris ssp. [21]. Progoitrin, the precursor of goitrin (5-vinyloxazolidine-2-thione) as the thyroid toxin, was not detected in the Korean leaf mustard germplasm.…”

Glucosinolate biosynthetic genes in Brassica rapa

“…2). Coincidentally, hydroxyalkyl glucosinolates are not detected in B. rapa (Kim et al, 2010;Lou et al, 2008;Padilla et al, 2007). In addition, an extra copy of AOP2 might catalyze formation of more alkenyl glucosinolate and its downstream derivatives.…”

“…To date, 17 different GS have been identified in B. rapa, of which 10 of are aliphatic GS, but the dominant GS were gluconapin (NAP), glucobrassicanapin (GBN) and progoitrin (PRO) (Kim et al, 2010;Lou et al, Fig. 2.…”
