When breeding diploid potatoes, tetraploid progeny can result from the union of 2n eggs and pollen in 2x-2x crosses. Thirty-three crosses were made to examine frequency All between S. tuberosum dihaploids self-compatible donors, M6 DRH S6-10-4P17. Using chloroplast counting for ploidy determination, was as high 45% one 33 Based upon single nucleotide polymorphism (SNP) genotyping, attributed bi...

background: vasopressin type 2 receptor (v2r) plays an important role in the water reabsorption in the kidney collecting ducts. v2r is a g protein coupled receptor (gpcr) and the triplet of amino acids aspartate-arginine-histidine (drh) in this receptor might significantly influence its activity similar to other gpcr. however, the role of this motif has not been fully confirmed. therefore, the ...

Sea-salt aerosol (SSA) particles are ubiquitous in the marine boundary layer and over coastal areas. Therefore SSA have ability to directly and indirectly affect the Earth’s radiation balance. The influence SSA have on climate is related to their water uptake and ice nucleation characteristics. In this study, optical microscopy coupled with Raman spectroscopy was used to detect the formation of...

The behavior of NaCl nanoparticles as a function of relative humidity (RH) has been characterized using non-contact environmental atomic force microscopy (e-AFM) to measure the heights of particles deposited on a prepared hydrophobic surface. Cubic NaCl nanoparticles with sides of 35 and 80 nm were found to take up water reversibly with increasing RH well below the bulk deliquescence relative h...

Developmental methylmercury (MeHg) exposure produces response perseveration on discrimination reversal procedures, disrupts sensitivity to reinforcement, and enhances sensitivity to dopamine agonists - a profile suggesting a deficit in behavioral inhibition. To examine inhibition, we examined MeHg's effects on the acquisition and persistence of low-rate lever-pressing following a history of hig...

Many helicases have a unique ability to couple cognate RNA binding to ATP hydrolysis, which can induce a large conformational change that affects its interaction with RNA, position along RNA, or oligomeric state. A growing number of these helicases contribute to the innate immune system, either as sensors that detect foreign nucleic acids and/or as effectors that directly participate in the cle...
