High seed vigor is important for agricultural production due to the associated potential for increased growth and productivity. However, a better understanding of the underlying molecular mechanisms is required because the genetic basis for seed vigor remains unknown. We used single-nucleotide polymorphism (SNP) markers to map quantitative trait loci (QTLs)(More)
Plant height is one of the most heritable traits in maize (Zea mays L.). Understanding the genetic control of plant height is important for elucidating the molecular mechanisms that regulate maize development. To investigate the genetic basis of the plant height response to density in maize, we evaluated the effects of two different plant densities (60,000(More)
BACKGROUND Leaf width is an important agricultural trait in maize. Leaf development is dependent on cell proliferation and expansion, and these processes exhibit polarity with respect to the longitudinal and transverse axes of the leaf. However, the molecular mechanism of the genetic control of seed vigor remains unknown in maize, and a better understanding(More)
The internode length above the uppermost ear (ILAU) is an important influencing factor for canopy architecture in maize. Analyzing the genetic characteristics of internode length is critical for improving plant population structure and increasing photosynthetic efficiency. However, the genetic control of ILAU has not been determined. In this study,(More)
The aims of this work were designed to investigate the hepatoprotective and antioxidant effects of acidic- and alkali-extractable mycelia zinc polysaccharides (AcMZPS, AlMZPS) from Pleurotus eryngii var. tuoliensis on high-fat-high-cholesterol emulsion-induced hyperlipidemic mice. The in vivo experiments demonstrated that both AcMZPS and AlMZPS had(More)
The aim of the present study was to optimize the purification of mycelia selenium polysaccharides (MSPS) from Agrocybe cylindracea SL-02 and characterize their in vitro antioxidant and in vivo anti-ageing activities. The Box-Behnken experimental design (BBD) was evaluated, which showed that the optimum conditions included an extraction temperature of(More)
Exopolysaccharides (ExPSs) and endopolysaccharides (EnPSs) were isolated from mycelia and culture medium of Agaricus brasiliensis. Four polysaccharide fractions (ExPS-1-2, ExPS-2, EnPS-1, and EnPS-2) were puri¬fied from ExPSs and EnPSs using diethylaminoethyl anion exchange and a Sephadex G-100 gel filtration column, respectively, and their physicochemical(More)
The present work investigated the protective effects on liver, kidneys and pancreas of spent mushroom compost polysaccharide (SCP) and its hydrolysates (enzymatic- (ESCP) and acid-hydrolyzed SCP (ASCP)) from Hypsizigus marmoreus, in streptozotocin (STZ)-induced diabetic mice. The results showed that enzymatic (superoxide dismutase (SOD), glutathione(More)
In present study, a quadratic regression model based on the response surface methodology (RSM) coupled with Box-Behnken design (BBD) was employed to optimize the enzyme-assisted extraction (EAE) process of enzymatic-extractable Pleurotus djamor polysaccharides (EnPPs). By solving the regression equations and analyzing the model graphs, the optimum(More)
