breeding programs strategies depends on genetical mechanism of selection traits. in the present research, generation mean analysis with joint scaling test was performed to determine the gene action. f1, f2 and f3 generations, derived from roushan and kavir cross along with their parents were sown in a partial lattice design with two replications under stress condition at the research field of s...

Spring wheat yields across the Canadian prairies are rising, however, a yield gap remains between average and potential which can be explored further under Prairie conditions. The high rates of nitrogen (N) fertilizer required for current high-yielding cultivars may increase lodging risk adding to this gap. objectives study were determine influence intensive management through N fertilization p...

The Omicron (B.1.1.529) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was initially identified in November 2021 South Africa and Botswana, as well a sample from traveller Hong Kong1,2. Since then, has been detected globally. This appears to be at least infectious Delta (B.1.617.2), already caused superspreader events3, outcompeted within weeks several countries metropo...

MXene-Based Aptameric Fluorosensors The aptamer-functionalized MXene nanosheet acts as an effective bionanosensor for fluorescence-enhanced detection of COVID-19 with high sensitivity and specificity. This fluosensor is capable detecting SARS-CoV-2 spike protein (limit detection: 38.9 fg mL−1) pseudovirus 7.2 copies) within 30 min, can also detect clinical samples. More details be found in arti...

Introduction: The COVID-19 pandemic has cast a heavy toll in human lives and global economics. is caused by the SARS-CoV-2 virus, which infects cells via its spike protein binding ACE2. Methods: To discover potential inhibitory peptidomimetic macrocycles for spike/ACE2 complex we deployed Artificial Intelligence guided virtual screening with three distinct strategies: 1) Allosteric inhibitors 2...

background and aims: ndv (newcastle disease virus) is one of the viruses that cause disease in avian with severe economic losses in the poultry industry in many countries. fusion protein (f) which plays a major role in the virus pathogenicity contains several regions that have a role in the fusion process. mutation in the sequence of hr1 & hr2 regions of this protein prevents fusion of the viru...

the green fluorescent protein (gfp) was originally isolated from the jellyfish aequorea victoria that fluoresces green when exposed to blue light. gfp protein is composed of 238 amino acids with the molecular mass of 26.9 kd. the gfp gene is frequently used in cellular and molecular biology as a reporter gene. to date, many bacterial, yeast , fungal, plants, fly and mammalian cells, including h...
