Non-heading Chinese cabbage, a variety of Brassica campestris, is an important vegetable crop in the Yangtze River Basin of China. However,the immaturity of its stable transformation system and its low transformation efficiency limit gene function research on non-heading Chinese cabbage. Agrobacterium rhizogenes-mediated(ARM) transgenic technology is a rapid and effective transformation method that has not yet been established for non-heading Chinese cabbage plants. Here, we optimized conventional ARM approaches(one-step and two-step transformation methods) suitable for living non-heading Chinese cabbage plants in nonsterile environments. Transgenic roots in composite non-heading Chinese cabbage plants were identified using phenotypic detection, fluorescence observation, and PCR analysis. The transformation efficiency of a two-step method on four five-day-old non-heading Chinese cabbage seedlings(Suzhouqing, Huangmeigui, Wuyueman, and Sijiu Caixin) was 43.33%-51.09%, whereas using the stout hypocotyl resulted in a transformation efficiency of 54.88% for the 30-day-old Sijiu *** one-step method outperformed the two-step method;the transformation efficiency of different varieties was above 60%, and both methods can be used to obtain transgenic roots for functional studies within one month. Finally, optimized ARM transformation methods can easily,quickly, and effectively produce composite non-heading Chinese cabbage plants with transgenic roots, providing a reliable foundation for gene function research and non-heading Chinese cabbage genetic improvement breeding.

Protective effect of Fu Brick tea on high-fat diet-induced metabolic syndrome: Relevant to protecting the intestinal barrier and regulating the gut microbiota

引用

Food Science and Human Wellness 2024年

作者： Wenwen Fang Fang Zhou Kuofei Wang Shuai Wen Hongzhe Zeng Hao Xu Jingyi Tang Jian-an Huang Zhonghua Liu Key Laboratory of Tea Science of Ministry of Education national research center of engineering and technology for Utilization of Botanical Functional Ingredients Key Laboratory for Evaluation and Utilization of Gene Resources of Horticultural crops Ministry of Agriculture and Rural Affairs of China Hunan Agricultural University

This study investigated the therapeutic effects on metabolic syndrome (MetS) and the impact on the intestinal barrier and gut microbiota of Fu brick tea aqueous extracts (FTE) on metabolic syndrome (MetS) in rats fed with a high-fat diet (HFD). Here， the results showed that FTE supplement significantly reduced HFD-induced weight gain， adiposity， dyslipidemia， fasting blood glucose (PBG) increment， and non-alcoholic fatty liver disease (NAFLD). Moreover， FTE supplement resulted in a decline in lipopolysaccharide (LPS) level and attenuation of colonic inflammation and oxidative stress to protect the intestinal barrier function. FTE supplement also maintained the intestinal barrier integrity by improving histological appearance and promoting ZO-1， Occludin， and Claudin-1 protein expression levels. Meanwhile， FTE supplement alleviated the gut microbiota dysbiosis by enhancing the Firmicutes/Bacteroidetes (F/B) ratio and stimulating the colonization of probiotic bacteria such as Akkermansia， Lactobacillus， Adlercreutzia， and Bacteroides. These findings collectively suggest that Fu brick tea could alleviate MetS and Mets-associated traits with the mechanism relevant to the protection of intestinal barrier and gut microbiota regulation.
