Trehalose can reduce stomatal aperture by a hydrogen-peroxide-dependent pathway in Vicia faba L. (cv. Daqingpi) resulting in significantly lower values of net photosynthetic rate (PN), stomatal conductance (gs), and transpiration rate (E). At 8 and 24 h, the lower PN in trehalose-treated plants was accompanied by significant decrease in intercellular CO2(More)
Anti-sera against a complement-activating pectin (AR-2IIb), which was purified from the roots of Angelica acutiloba Kitagawa, were obtained by immunization of rabbits, and a polyclonal anti-AR-2IIb antibody of the IgG class was purified by affinity chromatography on AR-2IIb-immobilized Sepharose and Protein G-Sepharose. Periodate oxidation of AR-2IIb(More)
This paper reports the device process and reliability aspects of a high voltage InGaP/GaAs HBT technology for 28V operation. The key differences and challenges from the material and process perspectives relative to the conventional low voltage HBT technology are first described. Long-term reliability tests performed at 28V bias voltage, 5.2kA/cm<sub>2</sub>(More)
Nitrogen (N) and phosphorus (P) concentrations and N: P ratios between leaves and roots of Nitraria tangutorum along aridity gradients were studied. N. tangutorum was relatively limited by N in April (mean leaf N: P ratio = 11.13) and by P in August (mean leaf N: P ratio = 38.78). N and P in both leaves and roots were highly correlated across sampling(More)
Quantitative real-time PCR (qRT-PCR) has becoming a widely used method for detection and characterization of gene expression in recent years. However, the accuracy of the qPCR output strongly depends on the performance of selected internal reference genes. In this study, we used periwinkle as material to select the most stably expressed reference genes(More)
