摘要： Glucosinolate (GSL) not only has highly physiological function for plants but also has considerable human interest. We analyzed the GSL compositions and levels in four organs of 111 radish accessions. Seven major GSLs were detected (approximately 5-245 mu mol g(-1) DW), among which 4-(methylsulfinyl)but-3-enyl GSL and 4-methylsulfanyl-3-butenyl GSL were the dominant GSLs. GSL levels varied substantially among species and groups, and some genotypes/groups with special GSL profiles were identified. The total GSL level was higher in seeds than in sprouts, taproots, and leaves. Additionally, a correlation analysis revealed that seed 4-(methylsulfinyl)but-3-enyl GSL levels were highly correlated with sprout GSL levels. Moreover, a candidate gene (RsCYP81F2.3) encoding an enzyme that catalyzes the conversion of indol-3-ylmethyl GSL to 4-hydroxyindol-3-ylmethyl GSL was identified based on the detection and analysis of three radish accessions with relatively high indol-3-ylmethyl GSL, low 4-hydroxyindol-3-ylmethyl GSL, and 4-methoxyindol-3-ylmethyl GSL levels in their seeds. Our results provide some insights for finding materials and genes relevant for breeding new varieties with ideal GSL compositions and levels.
