  • Alternaria black spots or blights in cruciferous crops have been devastating diseases worldwide and led to economic losses in broccoli, Chinese cabbage, kale, radish, rapeseed, etc. These diseases are caused by different Alternaria spp., including A. brassicae, A. brassicicola and A. raphani transmitted from infected seeds or insect vectors. Efforts to excavate disease resistance traits of cruciferous crops against Alternaria black spots or blights have been demonstrated. Genetic resource of disease resistance was investigated in the wild relatives of cruciferous crops, and different cultivars were screened under different inoculation conditions. Development of the disease-resistant lines against Alternaria black spots or blights was also tried via genetic transformation of the cruciferous crops using diverse plant defence-associated genes. Plant immunity activated by pre-treatment with chemicals, i. e. β-amino-n-butyric acid and melatonin, was suggested for reducing Alternaria black spots or blights in cruciferous crops. The disease resistance traits have also been evaluated in model plant Arabidopsis originating from different habitats. Various plant immunity-related mutants showing different disease responses from wild-type Arabidopsis provided valuable information for managing Alternaria black spots or blights in cruciferous crops. In particular, redox regulation and antioxidant responses altered in the Alternaria-infected mutants were discussed in this review.

  • Total 29 commercial crucifer seed lots were tested for seed transmission of Xanthomonas campestris pv. campestris by seed washing liquid plating assay. One imported cabbage seed lot was found to carry Xanthomonas campestris pv. campestris. Several methods and chemicals for eradication of Xanthomonas campestris pv. campestris in and on the cabbage seed were tested for effectiveness. Soaking cabbage seed in $3\3%$ hydrogen peroxide solution for 30 minutes effectively eradicated Xanthomonas campestris pv. campestris in a naturally infested seed lot. In a field survey, black rot turned out to be an important disease in cabbage in Korea.

  • Alliaria petiolata (M. Bieb.) Cavara & Grande (Brassicaceae) is an invasive species which is native in Europe and SW Asia. This species is currently invading the understory of mature temperate forests of North America. In Korea, A. petiolata is found to invade and colonize areas at forest margins along roadsides (Samcheok- si, Gangwon-do). This initial investigation serves to inform of the importance of early detection and extermination of this particular weed in Korea.

  • A seed coating system was developed to screen non-viable seeds in the Brassicaceae. The crops studied were radish, chinese cabbage, broccoli, cauliflower and brussel sprout. Sinapine leaked more from artificially deteriorated seeds than non-deteriorated seeds. Seed coating with cellulose was to trap the sinapine leakage in the non-viable Brassicaceae vegetable seeds. The seeds were first hydrated, then coated with cellulose powder to capture the leakage. Coated seeds were dried, then sorted two fractions-fluorescent seeds and non-fluorescent seeds under the UV light. The ratio of the fluorescent seeds were higher in bad seedlot than good one. The germination rate were increased 3∼35% by eliminating the fluorescent seeds in tested Brassica vegetable seeds. Sowing non-fluorescent seeds resulted in a greater percent normal seedling than non-coated seeds in all seedlots. The fluorescent seeds contained a high percentage of the dead and abnormal seedlings.
