BACKGROUND Plant protoplasts, a proven physiological and versatile cell system, are widely used in high-throughput analysis and functional characterization of genes. Green protoplasts have been successfully used in investigations of plant signal transduction pathways related to hormones, metabolites and environmental challenges. In rice, protoplasts are(More)
Maize inflorescence provides a useful model to study the genetic and molecular control of meristems. Many classical maize mutants were described last century, providing important insights into the mechanism of developmental control. The fea*-9LB030 is a new maize spontaneous mutant controlled by a single recessive gene. The ears are fasciated in line at the(More)
It has been previously shown that peroxisome proliferators-activated receptor gamma (PPAR-γ) is beneficial for nervous system injury. In present study, we examined the effect of rosiglitazone, a PPAR-γ agonist, on spinal cord injury (SCI) in rats. SCI was induced by dropping a 10g weight rod at a height of 25mm. The animals were randomly divided into(More)
The purpose of this study was to test the hypothesis that the interaction between abscisic acid (ABA) and ethylene may be involved in mediating the post-anthesis development of spikelets in rice (Oryza sativa L.). Two rice genotypes were field-grown, and the changes of ABA, ethylene, and 1-aminocylopropane-1-carboxylic acid (ACC) levels in spikelets during(More)
The insulin-like growth factor 1 (IGF1) gene was studied as a candidate gene for high prolificacy in sheep. Polymorphisms of 5′ regulatory region and all four exons of IGF1 gene were detected in Small Tail Han (n = 277), Hu (n = 58), Texel (n = 48) and Dorset (n = 46) sheep by PCR-RFLP and PCR-SSCP analysis. A microsatellite polymorphic site and a(More)
Archaea have multiple roles in global biogeochemical cycles. However, we still have limited knowledge about how environmental factors affect the diversity and function of different archaeal lineages. The goal of this study was to examine the change in the abundance and community structure of Archaea in the sediments collected from the lower Pearl River(More)
We determined the phosphate (P) uptake, substrate P concentration, phytase activity, acid phosphatase activity and expression of three predicted secreted purple acid phosphatase genes (PAPs) from trifoliate orange (Poncirus trifoliata L. Raf) through Glomus versiforme and phytin treatments to evaluate phytate-phosphorus utilization promoted by arbuscular(More)
Many works showed that nerve growth factor (NGF) injected into the brain of animal model emerges potential antidepressant effects. However, this route of administration significantly restricts the application of NGF clinically. Here, we reported that intranasal NGF could provide an alternative to intraventricular injection. The behavioral analysis showed(More)
A portable multi-channel telemetry system which can be used for brain stimulation and neuronal activity recording in freely behaving small animals is described here. This system consists of three major components of headstage, backpack and portable Personal Digital Assistant (PDA). The headstage contains high precision instrument amplifiers with high input(More)
Inhibitors of phosphodiesterase-4 (PDE4) are efficacious for allergic asthma in animal models and have shown some efficacy in human asthma. Regulation of PDE4 in allergy and asthma has been widely investigated in blood leukocytes, with discrepant results. This study investigated PDE4 regulation in the lung in a rat model of allergic asthma. Ovalbumin(More)
