A biocontrol strain,XF-1,was identified as Bacillus subtilis based on morphology,physiology,biochemistry and biotechnology,which could control clubroot of cruciferous crops effectively.

The character of harmfulness is that clubroot of crucifers is occurred yearly,severely in summer and autumn,slightly in winter and spring.

Uptake and accumulation of lead by five plants from colewort of Cruciferae;

Effect Test of Several Pesticides Controlling Plutella xylostella(L.) of Cruciferae;

Comparative Study on Some Biochemical Index of Three Cruciferae Plants;

Studies on the Leaf Epidermal Features of Lepidium (Brassicaceae) from China;

Analysis on Geographical Elements of Brassicaceae Area of Xinjiang;

The Phenology of Ephemeral Plants of Eight Brassicaceae and Its Adaptation to the Desert Environment;

Crucifer crops are sensitive to sulphur, the output of crucifer crops can be enhanced by applying sulphur fertilizer.

The clubroot disease of cruciferous plants is induced by Plasmodiophora brassicae Woronin, plasmodium fungus.

Wu39-1(Eruca sativa),Wu43-1(Brassica rapa) and Wu50-2 (Brassica napus) were used to develop a handy extraction method of mtDNA in crucifers on the basis of the sucrose-bedding method of mtDNA extraction and by means of four combinations of different centrifugal forces,differential centrifugation,and composition adjustment and dosage increase of buffer solution A.
