The consecutive monoculturing of peanut seriously affects its yield and quality in the red soil regions of southern China. Different control measures for consecutively monocultured peanut fields should be explored to ensure the sustainable development of the local peanut industry. In this study, the influence of two different regimes, the intercropping of(More)
Anaerobes can obtain the entire cell's ATP by glycolysis and remove resulting reducing power by fermentation. There is a delicate balance in redox status to obtain a maximal growth of these cells, and the conditions to change redox fluxes can induce kinds of changes in metabolism. The fundamental knowledge on sensing redox status and coupling redox signals(More)
In natural ecosystems, endophytes, which live in the inner tissues of healthy plants, exhibit complex interactions with their hosts. During a long coevolutionary process with their hosts, endophytes have developed many significant and novel characteristics. In order to maintain a stable symbiosis, endophytes secrete varieties of extracellular enzymes that(More)
Resveratrol, a major stilbene phytoalexin, is a valuable polyphenol that has been recognized for its benefits to human health. Resveratrol has antioxidant and antitumor effects and promotes longevity. It is used in medicine, health care products, cosmetics, and other industries. Therefore, a sustainable source for resveratrol production is required. This(More)
Diverse intercropping is an effective way to control crop disease and improve productivity. The aim of this study was to investigate the effects of intercropping peanut (Arachis hypogaea L.) with the medicinal plant Atractylodes lancea on peanut yield and on the microbial community in the soil. A. lancea was intercropped with peanut in an upland that had(More)
In this study, we investigated the photosynthetic physiological basis in 'PC' transgenic rice (Oryza sativa L.), showing high-level expression of the gene encoding C4 phosphoenolpyruvate carboxylase (pepc), by hydrogen peroxide (H2O2). The C4-PEPC gene (pepc) from maize in the transgenic rice plants was checked by PCR. Comparison of yield components and(More)
Five fungi species including Rhizoctonia sp., Sclerotium sp., Acremoniell sp., Chaetomium sp. and Pestalotiopsis sp. screened from the inner bark of Sapium sebiferum (Lével) Roxb. were used to study their growth under different environmental factors, with the biomass and fatty acid composition as main indexes to elucidate the relationship between plant and(More)
A new full-length cDNA encoding 3-hydroxy-3-methylglutoryl-Coenzyme A reductase (HMGR; EC1.1.1.34), which catalyzes the first committed step of isoprenoids biosynthesis in MVA pathway, was isolated from young leaves of Euphorbia Pekinensis Rupr. by rapid amplification of cDNA ends (RACE) for the first time. The full-length cDNA of HMGR (designated as(More)
The progress of genetically engineered microbial whole-cell biosensors for chemosensing and monitoring has been developed in the last 20 years. Those biosensors respond to target chemicals and produce output signals, which offer a simple and alternative way of assessment approaches. As actual pollution caused by human activities usually contains a(More)
A strain of poly(β-hydroxybutyrate) (PHB)-accumulating bacterium was isolated from the soil in Alaska of USA, identified as Pseudomonas fluorescens, and designated as strain A2a5. The organism grew at temperatures below 30°C, and accumulated a large amount of granules in its cells when it was cultured in the sugarcane liquor medium. The purified sample from(More)
