Breeding ‘Chinese Cabbage Parental Line Nou-6’ with Bolting Resistance

Physiological and Biochemical Properties Analysis of Late-bolting Transgenic Chinese Cabbage (brassica Rapa L. Ssp. Pekinensis)

LFYgene plays important roles in determining plant flowering mainly by controlling the timing of phase transition. Constitutive under-expression of LFY gene in Arabidopsis resulted in the formation of late flowering and highly branching phenotype. In this paper, we investigated some physiological and biochemical properties of the transformantsthat were down-regulated LFY gene expression to dela...

Infection of Plasmodiophora brassicae in Chinese cabbage.

Brassica crops infected by Plasmodiophora brassicae can produce root galls (clubroots) and be prevented from growing normally. To understand the series of changes that occur in the host root during root gall production, the resistance character of 21 Chinese cabbage lines were identified and then resistant and susceptible lines were used for infection observation. Hydroponic technology system w...

Chinese Experiences in Breeding Three-Line, Two-Line and Super Hybrid Rice

Kinetin and carbohydrate metabolism in chinese cabbage.

The effects of kinetin on starch and sugar levels and on (14)CO(2) and (32)P-orthophosphate labeling patterns of floated Chinese cabbage (Brassica pekinensis) leaf discs were investigated. Kinetin caused gross starch degradation. Neutral sugars were depressed by 30 to 40% in leaf tissue treated with kinetin for 24 hours. (14)CO(2) labeling of leaf discs pretreated with kinetin for 24 hours show...

From Chinese Cabbage and Photosynthetic Microorganisms

Ribulose-1,5-diphosphate carboxylase (carboxydismutase) was prepared from Chinese Cabbage [Brassica petsai (Parl)] and the Km values and molecular weight were determined. These parameters were found to be in good agreement with values reported for this enzyme from other higher plants. Investigation of carboxydismutase activity from the photosynthetic micro-organisms Chlamydomonas reinhardi (IU ...
