Microspore cell death and low green plant production efficiency are an integral obstacle in the development of doubled haploid production in wheat. The aim of the current study was to determine the effect of anti-apoptotic recombinant human B-cell lymphoma-2 (Bcl-2△21) and caspase-3-inhibitor (Ac-DEVD-CHO) in microspore cell death in bread wheat cultivars AC Fielder and AC Andrew. Induction med...

Mapping gene(s) underlying a specific trait offers an opportunity to plant breeders to apply marker assisted selection. All gene mapping approaches except LD mapping use family based segregation populations developed by crossing two or more parents. These family based gene mapping approaches include simple interval mapping, composite interval mapping, multiple interval mapping and Bayesian mapp...

Despite the prominent roles played by R2R3-MYB transcription factors in the regulation of plant gene expression, little is known about the details of how these proteins interact with their DNA targets. For example, while Arabidopsis thaliana R2R3-MYB protein AtMYB61 is known to alter transcript abundance of a specific set of target genes, little is known about the specific DNA sequences to whic...

knowledge of the relation between agronomical traits with economical yield is very important in crop improvement and breeding. in order to study of genetic diversity and identifying yield components, 568 kabuli type germplasm and 390 desi type chickpea germplasm that were available in pulses collection of faculty of agriculture, university of tehran, was investigated in this research in 2009 in...

Abstract. This work presents the design of robust sliding mode controllers for three-phase ac-ac matrix converters, in order to guarantee output sinusoidal waveforms and near unity input power factor. First, the sliding mode controller, based on the state-space vectors modulation technique, is designed for the matrix converter and the obtained results are compared to those obtained using the cl...

A high-speed capacitance difference-to-sum ratio measurement circuit is presented for differential capacitance transducers. It consists of a switched-capacitor input stage, two sample-and-hold (S/H) circuits followed by voltage-to-current (V/I) converters, and a current-ratio-controlled relaxation oscillator. This circuit offers a square-wave output whose oscillation period is directly proporti...

Production planning is performed through diverse methods according to the type of the system it is structured upon. One of the most important steps before production planning is to determine which system best fits the firm, and how the facilities should be designed. Both job-shop and group-technology systems have their own cons and pros, each of which is suitable to a specific kind of factory. ...

Azorella compacta Phil. (AC) is an alpine medicinal plant used traditionally for antibacterial treatment. Recent studies have revealed that this plant also has anti‑diabetic effects, but that it is toxic. The present study investigated the underlying mechanisms of action of AC extract against human leukemia HL60 cells. Apoptosis induction was measured by MTT assay, fluorescence microscopy, DNA ...
