to estimate the optimum and effective amount of nitrogen fertilizer for quantity and quality improvement of three new durum wheat lines, this research was conducted in gachsaran dry-land agricultural research station for a duration of 4 years (2003-2007). the study was performed as a factorial expriment, using a randomized complete block design with 4 replications. two factors of: 4 nitrogen ra...

Previous studies which used intertypic reassortants of the wild-type reovirus serotype 1 Lang and the temperature-sensitive (ts) serotype 3 mutant clone tsA279 identified two ts lesions; one lesion, in the M2 gene segment, was associated with defective transmembrane transport of restrictively assembled virions (P. R. Hazelton and K. M. Coombs, Virology 207:46-58, 1995). In the present study we ...

Grain yield in bread wheat (Triticum aestivum L.) is largely determined by inflorescence architecture. Zang734 an endemic Tibetan variety that exhibits a rare triple spikelet (TRS) phenotype with significantly increased spikelet/floret number per spike. However, the molecular basis underlying this specific spike morphology completely unknown. Through map-based cloning, causal genes for TRS trai...

objective: toxoplasmosis can lead to severe pathological effects in both infected humans and animals. the various dna vaccines against toxoplasma compose of single or cocktail antigens have been investigated but they have partial protective against disease. in this study, we used pcrop1 as a dna vaccine and aluminium phosphate and aluminium hydroxide to compare their efficacy as mineral adjuvan...

Since the beginning of pandemic, a race has been underway to detect SARS-CoV-2 virus infection (PCR screening, serological diagnostic kits), treat patients (drug repurposing, standard care) and develop vaccine. After almost year active circulation worldwide, variants have appeared in different countries. Those include mutations multiple regions genome, particularly spike gene. Because this surf...

Temporal control of programmed cell death is necessary to ensure that cells die at only the right time during animal development. How such temporal regulation is achieved remains poorly understood. In some Caenorhabditis elegans somatic cells, transcription of the egl-1/BH3-only gene promotes cell-specific death. The EGL-1 protein inhibits the CED-9/Bcl-2 protein, resulting in the release of th...
