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)
BACKGROUND The 12-oxo-phytodienoic acid reductases (OPRs) are enzymes that catalyze the reduction of double-bonds in alpha, beta-unsaturated aldehydes or ketones and are part of the octadecanoid pathway that converts linolenic acid to jasmonic acid. In plants, OPRs belong to the old yellow enzyme family and form multigene families. Although discoveries(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)
BACKGROUND Chemokines and their receptors are known to play important roles in the tumorigenesis of many malignancies. The aim of this study was to evaluate the prognostic impact of the expression of the chemokine SDF-1 and its receptors CXCR4 and CXCR7 in patients with renal cell carcinoma. METHODS The expression of CXCR4, CXCR7 and SDF-1 in specimens(More)
Recently, Apolygus lucorum (Hemiptera: Miridae) has become an important insect pest of Bt cotton and fruit trees in China. At present, the application of chemical insecticides is the main control option for this pest. We investigated the lethal effect of seven neonicotinoid insecticides on A. lucorum adults, including six commercialized neonicotinoids and a(More)
Cytoplasmic genetic male-sterility is used to produce hybrid onion (Allium cepa L.) seeds worldwide. In this paper, we present the results of research aimed toward identifying PCR-based markers linked to the Ms locus through amplified fragment length polymorphism (AFLP). After screening 512 AFLP primer combinations, only one AFLP fragment was identified as(More)
BACKGROUND Smoking is a risk factor for many human diseases. DNA methylation has been related to smoking, but genome-wide methylation data for smoking in Chinese populations is limited. OBJECTIVES We aimed to investigate epigenome-wide methylation in relation to smoking in a Chinese population. METHODS We measured the methylation levels at > 485,000 CpG(More)
Castrated retired breeder male and female mice were treated or not with a 17 beta-estradiol pellet. At 10 days postcastration +/- estrogen treatment all animals were treated with MPTP. Five days later, concentrations of dopamine were determined from the corpus striatum and olfactory tubercle. Both castrated male and female mice treated with estrogen had(More)
In this report we examined the effect of tamoxifen upon the nigrostriatal dopaminergic system. Ovariectomized mice were subjected to one of the following treatments: two subcutaneous injections administered on successive days of the sesame oil vehicle (control), estradiol benzoate (EB-10 micrograms), tamoxifen citrate (TMX 125 micrograms) or a combination(More)
In the present study, we directly compare striatal dopamine metabolism in gonadectomized male and female CD-1 mice treated with 2 days of estrogen or oil vehicle. Basal and potassium-stimulated dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC) release from in vitro superfused striatum as well as pre- and postsuperfusion tissue dopamine contents were(More)
