Self-incompatibility (SI) prevents inbreeding through specific recognition and rejection of incompatible pollen. In incompatible Papaver rhoeas pollen, SI triggers a Ca2+ signaling cascade, resulting in the inhibition of tip growth, actin depolymerization, and programmed cell death (PCD). We investigated whether actin dynamics were implicated in regulating(More)
Yellow clayey paddy soil is a typical soil with low productivity in southern China. However, a systematic evaluation of soil quality, which is important for improving sustainable land use management and increasing crop yields, has not been carried out for yellow clayey paddy soils. This study adopted two indicator selection methods, Total Data Set (TDS) and(More)
This study was conducted to explore the modulation of GTPs on cognitive performances in psychological stress rats. Wistar rats were randomly assigned to five groups as follows: control group, stress group, and three stress groups with low, medium and high-doses of GTPs modulation respectively. The changes of cognitive performances were examined by(More)
The effects of glutamate (Glu) and glutamine (Gln) on learning and memory of rats and the mechanism involved were examined. Three groups of rats were fed with stock diet (control group), and the diets supplemented with 2% Glu (Glu group) or 2% Gln (Gln group) respectively. Compared with control group, the active avoidance response rats of Gln group in(More)
Glutaredoxins (GRXs) are small ubiquitous glutathione (GSH)-dependent oxidoreductases that catalyze the reversible reduction of protein disulfide bridges or protein-GSH mixed disulfide bonds via a dithiol or monothiol mechanism, respectively. Three major classes of GRXs, with the CPYC-type, the CGFS-type or the CC-type active site, have been identified in(More)
AIM To observe the effects of stress on Glu uptake and NMDAR of hippocampus synaptosome in rats with different zinc status. METHODS Stress model was established by photoelectric stimulus. The behaviors of rats were tested in open-field case. 3H-L-Glu was taken as radioligand to detect the NMDAR binding. Glu uptake was determined with radioimmunoassay. (More)
The effect of zinc on the damage of primary cultured hippocampal neurons induced by corticosterone (CORT) was studied. Neuronal injury and expression of NMDA receptor subunits (NR1,NR2A,NR2B) mRNA were detected by using in situ staining and RT-PCR, respectively. Neurons treated with 5 micromol/L CORT for 24 h showed decreased survival rates and increased(More)
In order to explore the effects of zinc deficiency on the behavior, [Ca2+]i and active CaM contents of hippocampal cells of rats, 21 male Wistar rats were randomly divided into 3 groups, i.e. zinc deficiency group (ZD), pair-fed group (PF), and control group (CT) fed with zinc deficiency (ZD group) and normal diets (PF and CT group). At the end of the third(More)
With the primary cultured cerebral cortex neurons of human fetus, studies were made to investigate the effect of zinc on the growth of neurons by using immunohistochemical stain and image analysis. The main results were as follows: (1) The growth of neurons of zinc group was the most prosperous at the 10-14 day of primary culture. The number of survival(More)
