in this study, 120 accessions of aegilops crassa collected from various geographical areas of iran were analyzed with respect to genome size and protein markers. a flow cytometry survey of these accessions revealed that one hundred and thirteen of the accessions were tetraploid and seven were hexaploid. moreover, these accessions revealed variations in high molecular weight glutenin subunit com...

to evaluate allelic diversity at loci encoding low molecular weight glutenin subunits (lmw-gs) among 62 genotypes of bread wheat, nine specific primer pairs for glu-a3, glu-b3, glu-d3 loci were employed. pcr products were separated on 2% agarose gels. two pairs of specific primers, at amplified glu-a3 locus, 8 alleles were detected the c allele of which was the most abundant with a frequency of...

The surface of the pneumococcal cell is adorned with virulence factors including pili. The major pilin RrgB, which forms the pilus shaft on pathogenic Streptococcus pneumoniae, comprises four immunoglobulin (Ig)-like domains, each with a common CnaB topology. The three C-terminal domains are each stabilized by internal Lys-Asn isopeptide bonds, formed autocatalytically with the aid of an essent...

The oxygen-evolving manganese cluster (OEC) of photosynthesis is oxidised by the photochemically generated primary oxidant (P(+*)(680)) of photosystem II via a tyrosine residue (Y(Z), Tyr161 on the D1 subunit of Synechocystis sp. PCC6803). The redox span between these components is rather small and probably tuned by protonic equilibria. The very efficient electron transfer from Y(Z) to P(+*)(68...

The aim of this work was to study release of glutamic acid (GLU) from one-axon terminal or bouton at-a-time using cortical neurons grown in vitro to study the effect of presynaptic auto- and heteroreceptor stimulation. Neurons were infected with release reporters SypHx2 or iGluSnFR at 7 or 3 days-in-vitro (DIV) respectively. At 13-15 DIV single synaptic boutons were identified from images obtai...
