The yield of maize grain is a highly complex quantitative trait that is controlled by multiple quantitative trait loci (QTLs) with small effects, and is frequently influenced by multiple genetic and environmental factors. Thus, it is challenging to clone a QTL for grain yield in the maize genome. Previously, we identified a major QTL, qKNPR6, for kernel(More)
A combination of the gel retardation assay and interference by hydroxyl radical modification (missing nucleoside technique) was used to analyze the interaction of the glucocorticoid receptor (GR) with various glucocorticoid responsive elements (GRE). Short oligonucleotides containing the 15-bp GRE and 1 to 3 flanking base pairs on each side, are bound with(More)
The influence of progesterone receptor (PR) and glucocorticoid receptor (GR) on transcription from the mouse mammary tumour virus (MMTV) promoter was analyzed using cell-free transcription of DNA templates with a G-free cassette. Preincubation of the templates with either PR or GR stimulates the rate of transcription initiation 10-50 fold, whereas the(More)
Fragments of the DNA-binding domain of the rat glucocorticoid receptor (rGR) and the human estrogen receptor (hER) were expressed in Staphylococcus aureus as a chimeric fusion to protein A by using a modified expression vector with an artificial factor X-cleavage site. The secreted product was isolated by hydrophobic chromatography on Phenyl-Sepharose and(More)
The effects of plasma treatment on the surface properties of Si-doped Al 0.5 Ga 0.5 N were studied by X-ray photoelectron spectroscopy and metal contact measurements. Plasma treatment resulted in a N-deficient nonstoichiometric AlGaN surface with an increased O concentration and large red shifts of photoelectron peaks. The red shifts remained after removal(More)
The effects of surface treatment using Cl 2 /BCl 3 and Ar inductive coupled plasmas on the Ohmic characteristics of Ti/ Al/ Ti/ Au contacts to n-type Al x Ga 1−x N ͑x =0–0.5͒ were investigated. Plasma treatment significantly increased the surface conductivity of GaN and Al 0.1 Ga 0.9 N, leading to improved Ohmic behaviors of the contacts. However, it(More)
OBJECTIVE The method is to be established to effectively promote the sensitivity of the detection of P16 gene deletion from tumor tissues mixed with normal cells and to determine the relationship between the gene alteration and the lung cancers. METHODS The normal DNA and that of MCF-7 cells with P16 gene deletion was proportionally mixed and the mixture(More)
