Salt-tolerant endophytic bacterium B30 enhance bermudagrass growth under salt stress by modulating plant physiology and changing rhizosphere and root bacterial community.

Osmotic and ionic induced salt stress suppresses plant growth. In a previous study, B30, isolated from , improved seed germination, root length, and seedling length of bermudagrass () under salt stress. In this study, B30 application improved fresh weight and dry weight, carotenoid and chlorophyll levels, catalase and superoxide dismutase activities, indole acetic acid content and K concentration.

Lanthanum Promotes Bahiagrass () Roots Growth by Improving Root Activity, Photosynthesis and Respiration.

Lanthanum (La), one of the most active rare earth elements, promotes the growth of turfgrass roots. In this study, the mechanisms by which La influences bahiagrass () growth were evaluated by the analyses of root growth, root activity, cell wall polysaccharide content, respiration intensity, ascorbic acid oxidase (AAO) and polyphenol oxidase (PPO) activity, the subcellular distribution of mitochondria, transcription in roots, photosynthetic properties, chlorophyll fluorescence parameters, and chlorophyll content. The application of 0.

Genetic variability and relationship between MT-1 elephant grass and closely related cultivars assessed by SRAP markers.

Genetic variability and relationships among elephant grass cultivars were estimated by the SRAP (sequence-related amplified polymorphism) assay. A total of 60 individuals collected from five cultivars in China were analysed. Sixty-two selected primer combinations generated 1395 bands, with an average of 22.

[Association of phytoplasma with Bermuda grass white-leaf disease].

Objective: Bermuda grass white leaf is an important disease on Bermuda grass all over the world. The aim of this research is to identify the pathogen which leads to Bermuda grass white leaf occurring on the Chinese mainland.

Methods: PCR amplification technique, sequence analysis and Southern hybridization were used.

[Clinical study of yishen jianpi yangxue tongli therapy in treating polycystic ovary syndrome].

Objective: To observe the effect of Yishen Jianpi Yangxue Tongli Therapy (YJYTT) in treating polycystic ovary syndrome (PCOS) and to explore the therapeutic mechanism of YJYTT.

Methods: One hundred and seven PCOS patients with syndrome differentiation of TCM as Pi-Shen Yang deficiency were randomly divided into two groups, the treated group (n = 76) was treated with Chinese herbal medicine, while the control group (n = 31) was treated by clomiphen. The therapeutic effect in both groups and the change of body mass index (BMI), Ferriman-Gallway (F-G) score, serum sex hormones and serum oral glucose tolerance test (OGTT) before and after treatment were observed.
