Anther Culture of Chinese Cabbage Resistant to Clubroot
Current biotechnology, 2011Co-Authors: Yang Xiao-yunAbstract:Chinese Cabbage is one of the important vegetables in northern China.Clubroot disease seriously influenced the production of Chinese Cabbage in the world.The use of anther culture can greatly accelerate breeding process of Chinese Cabbage resistant to clubroot.Thirty three Chinese Cabbage varieties(lines) resistant to clubroot were used to anther culture in this study.The results indicated that the embryo induction rate of varieties were 72.7%,and the highest rate was 1.86 embryos /bud for Oriental Crown×C11 lines.The medium plus 0.4 g/L glutamine was best for induction of most genotypes.The results also showed that donor plants growing in the greenhouse were easier to induce embryoids.Green cotyledon-type embryos were transferred to solid medium with B5+0.2 mg/L BA+0.1 mg/L NAA+0.1% activated carbon to induce adventitious buds.

Root exudates of potato onion are involved in the suppression of clubroot in a Chinese Cabbage-potato onion-Chinese Cabbage crop rotation
European Journal of Plant Pathology, 2018Co-Authors: Shaocan Chen, Xingang Zhou, Hongjie Yu, Fengzhi WuAbstract:Clubroot, caused by Plasmodiophora brassicae, has emerged as a serious disease threatening cruciferous crop production throughout the world. Crop rotation with non-host species is commonly practised to avoid clubroot, but it is not known whether rotation crops can control clubroot when the resting spores of P. brassicae remain unaffected. Pot experiments were performed to investigate the response of clubroot in Chinese Cabbage to crop rotation with potato onion. The results showed that Chinese Cabbage rotated with potato onion exhibited less clubroot disease than Chinese Cabbage monoculture. Compared with residues from potato onion, the addition of root exudates from potato onion significantly decreased the disease incidence and index of clubroot (p ≤ 0.05). Potato onion root exudates decreased the number of secondary plasmodia of P. brassicae and the expression of the PRO1 gene of P. brassicae. These results suggest that root exudates from potato onion may play an important role in suppressing clubroot in a Chinese Cabbage-potato onion-Chinese Cabbage rotation system.

evaluation of struvite obtained from semiconductor wastewater as a fertilizer in cultivating Chinese Cabbage
Journal of Hazardous Materials, 2012Co-Authors: Hongduck Ryu, Chaesung Lim, Minkoo Kang, Sangill LeeAbstract:The present work evaluated the fertilizing value of struvite deposit recovered from semiconductor wastewater in cultivating Chinese Cabbage. The fertilizing effect of struvite deposit was compared with that of commercial fertilizers: complex, organic and compost. Laboratory pot test results clearly showed that the growth of Chinese Cabbage was better promoted when the struvite deposit was used than with organic and compost fertilizers even though complex fertilizer was the most effective in growing Chinese Cabbage. It was revealed that potassium (K) was a key element in the determination of growth rate of Chinese Cabbage. Also, the abundant nutrients such as nitrogen (N), phosphorus (P), K, calcium (Ca) and magnesium (Mg) were observed in the vegetable tissue of struvite pot. Specifically, P was the most-founded component in the vegetable tissue of struvite pot. Meanwhile, the utilization of struvite as a fertilizer led to the lowest accumulation of copper (Cu) and no detection of cadmium (Cd), arsenic (As), lead (Pb) and nickel (Ni) in the Chinese Cabbage. It was found that the optimum struvite dosage for the cultivation of Chinese Cabbage was 1.6 g struvite/kg soil. Based on these findings, it was concluded that the struvite deposits recovered from semiconductor wastewater were effective as a multi-nutrient fertilizer for Chinese Cabbage cultivation.

ectopic expression of a Chinese Cabbage brargos gene in arabidopsis increases organ size
Transgenic Research, 2010Co-Authors: Bao Wang, Xincheng Zhou, Jianwei GaoAbstract:Chinese Cabbage (Brassica rapa L. ssp. pekinensis) is a common and economically important crop in Asia. Specific targets of plant breeding programs for Cabbage have been improvement in yield, resistance to environment stresses, and nutrition quality by means of genetic manipulation. To obtain information on yield improvement applicable for the genetic engineering approach, we have attempted to dissect the molecular pathways that regulate organ size. We first isolated a putative homolog of ARGOS full-length cDNA from Chinese Cabbage leaves, which we designated BrARGOS. At the transcription level, BrARGOS was detected in all organs tested in Chinese Cabbage. To test the function of this gene, we then engineered Arabidopsis plants that would overexpress BrARGOS ectopically. The organs of the transgenic Arabidopsis plants were significantly larger than those of the control plants. This increase in size was due to enhanced cell proliferation, with no contribution from cell expansion. The molecular analysis revealed that overexpression of BrARGOS up-regulated the transcription of several genes involved in the control of organ size. These results suggest that the BrARGOS gene may function as one of the regulators of organ size in Chinese Cabbage. As such, manipulation of the BrARGOS gene may significantly increase the size of Chinese Cabbage organs, such as Chinese Cabbage heads.
