[Integration and "Overview" analysis of QTLs related to plant height in soybean].

Plant height, one of the most important factors for plant architectures, is closely related with some important traits such as plant density, lodging resistance and yields.. In the present study, 201 QTLs related to plant height of soybean from database and references were analyzed.

[Comparison of low temperature- induced proteins in tillering node of winter wheat cultivars with different cold resistance].

By using two-dimensional electrophoresis and mass spectrometry techniques, the proteomes in the tillering node of cold-resistant winter wheat Dongnongdongmai 1 and cold-susceptible winter wheat Jimai 22 before and after low temperature treatment were comparatively analyzed. It was observed that within the range of pH 4-7, there was a significant difference in the expression level of 55 protein spots in the protein profiles of tillering node before and after low temperature treatment, and 47 of the 55 protein spots were expressed in the two cultivars. After low temperature treatment, the abundance value of 23 protein spots increased, with the absolute abundance being higher in Dongnongdongmai 1 than in Jimai 22, while that of 7 protein spots decreased, with the absolute abundance being lower in Dongnongdongmai 1 than in Jimai 22.

Antioxidant activities of extracts and fractions from Lysimachia foenum-graecum Hance.

The antioxidant activities of water extract, methanol extract, ethyl acetate, and n-BuOH fractions of methanol extract from Lysimachia foenum-graecum Hance were investigated in this study. Various methods, such as the total antioxidant capacity measured by phosphomolybdenum method, scavenging activities towards 1,1-diphenyl-2-picryhydrazyl (DPPH) radical, superoxide anion radical, and hydroxyl radical, were established in in vitro systems. The amounts of total phenolics and total flavonoids in the extracts and fractions were also determined by spectrophotometric methods.
