The isaria fumosorosea wettable powder is mainly used for preventing and treating brassicaceous vegetable pests, has good effect in preventing and treating pests such as plutella xylostella and the like, and has the advantages of high insecticidal activity, stable effect, lasting effect, small impact on environment, and convenience in use.

The invention relates to an InDel marker related to dominant bright green characters of Chinese cabbage, a primer of the InDel marker, and an application of the InDel marker and the primer. A brassicacrop is a common crop with scapes as edible parts, and plants having a bright green epidermis trait are generally preferred by consumers. According to the invention, a mutant with a bright green character controlled by a dominant and single gene, and a bright green gene locus GL A09-2 and a unique candidate functional gene Bra024697 are determined through the bright green mutant gene controlled by the dominant gene through a bioinformatics technology. As a parent material, the mutant individuals can obviously reduce the workload of screening bright green character individuals, and have important significance for breeding of brassica crops.

The invention relates to an isothiocyanate-enriched vegetable condiment and a production method thereof, and belongs to the technical field of food processing. The isothiocyanate-enriched vegetable seasoning powder comprises cruciferae ripe vegetable powder and sprout vegetable powder thereof, wherein the weight ratio of the cruciferae ripe vegetable powder to the sprout vegetable powder is 1 to (1-5), and the content of isothiocyanate in the vegetable seasoning powder is 800-2500mg / 100g by dry weight.

The invention concerns a polypeptide which can be isolated from the Brassicaceae family and which has at least the activity of a hydroxynitrile lyase (HNL). The hydroxynitrile lyase of the invention is the first HNL from the Brassicaceae family. The plants (Arabidopsis) from which this enzyme or its gene is isolated is also described as non-cyanogenic. All HNL-containing plants described so far are cyanogenic plants and so it has until now been assumed that only cyanogenic plants contain hydroxynitrile lyases. Surprisingly, it transpires that a polypeptide (AtHNL) of the invention is (R)-selective. The amino acid sequence gives a theoretical molecular weight of 29.2 kDa for the AtHNL subunit. The calculated molecular mass of the protein of approximately 30 kDa can be confirmed by SDS gel electrophoresis.
