In study, spherical Silver nanoparticles (SNPs) were synthesized by chemical reduction method from a metal precursor silver nitrate in presence of an anionic surfactant and strong reducing agent. In this experimental work, SNPs are synthesized in presence of different concentration of stabilizing agent and effect of stabilizing agent on size distribution of SNPs have been observed. Further anti...

The Tabebuia alliance is widely planted in tropical and subtropical countries. However, the lack of accurate taxonomic information for many commercial cultivars leads to disputes. We sought clarify background China provide a robust basis patent protection. collected 82 12 reference individuals, then developed large-scale single nucleotide polymorphism (SNP) markers using genotyping-by-sequencin...

Common bean (Phaseolus vulgaris L.) is an important export crop in Kyrgyzstan. The aim of this study was to assess the extent of genetic diversity, determine the population structure, and relate to the main gene pools grown in Kyrgyzstan. Twenty-eight common bean accessions (including five Kyrgyz cultivars, and main references from the Mesoamerica and South America) were evaluated with microsat...

The breeding biology of a captive, isolated population Dalmatian Pelicans (Pelecanus crispus) at theShanghaiZoo,China, was studied from 2007 to 2019. age the estimated three four years old, and they started in late October or early November. clutch size varied between one two eggs per nest, were 83.2 ±4.8 mmin length, 55.6 ±2.9 breadth 136.1 ±21.5 gin weight. fertility fluctuated slightly, with...

common kilka clupeonella cultriventris (nordmann, 1840) is a brackish water and small pelagic fish species and is one of the most abundant fishes that live gregariously in the caspian sea. a total of 60 specimens of adult common kilka were sampled from two seasons. fifteen pairs of microsatellites previously developed for a.sapidissima, c. pallasi, c.harengus, and s. pilchardus were tested for ...

Double strand breaks (DSBs) are often repaired via homologous recombination. Recombinational repair processes are expected to be influenced by nucleotide heterozygosity through mismatch detection systems. Unrepaired DSBs have severe biological consequences and are often lethal. We show that natural selection due to inhibition of recombinational repair associated with polymorphisms could influen...

UNLABELLED PREMISE OF THE STUDY Spartina alterniflora is one of the nine most notoriously invasive plants in China. Microsatellite markers were developed for this species to investigate its invasiveness and genetic diversity. • METHODS AND RESULTS Fifteen polymorphic and seven monomorphic simple sequence repeat (SSR) markers derived from expressed sequence tags (ESTs) were identified and s...

PREMISE OF THE STUDY Pinus armandii (Pinaceae) is an important conifer tree species in central and southwestern China, and it plays a key role in the local forest ecosystems. To investigate its population genetics and design effective conservation strategies, we characterized 18 polymorphic microsatellite markers for this species. METHODS AND RESULTS Eighteen novel polymorphic and 16 monomorp...

According to circumstance of kerman sarcheshmeh cooper complex that its anode slime is mainly consisted of Cu, Ag, Au, Pb and Se. In this work, recovery of silver from anode slime and subsequent synthesis of silver nanoparticles from leaching solution was made. Silver was separated from anode slime by using of HNO3 and HCl. X-Ray fluorescence spectroscopy (XRF) was used to characterize anode sl...
