the emergence of plasmodium vivax in dashte moghan in northwestern iran has become a major concern for iranian's health officials. knowledge of genetic make up of the p. vivax populations in this area would give us an insight into the origin of the prevalent infections and the possible routes they are introduced. this paper reports the analysis of a variable region between the two interspecies ...

The aim of this study was to determine nature and extent of variability parameters and their utilization in barley breeding programme. A total of 45 F1s along with their parents and F2 populations were evaluated in a randomized block design with 3 replications during Rabi (winter season) 2014. The various traits measured were days to 50% flowering, days to maturity, plant height, flag leaf area...

a partial set of diallel crosses conducted among seven bread wheat genotypes contain (gasspard,m86-4,m86-6,dn-11,ws82-9 and m86-12) along with 21 hybrid, based on randomized complete block design(rcbd) with three replication were evaluated. the experiment was accomplished in a research field of agriculture and natural research center of tehran province in 2012-2013 in order to study genetic ana...

A complete genome sequence of an avian coronavirus (AvCoV; 27,663 bp excluding 3′ poly(A) tail) was determined using nontargeted next-generation sequencing (NGS) oropharyngeal swab from a backyard chicken in live bird market Arusha, Tanzania. The open reading frames (ORFs) the Tanzanian strain TZ/CA127/19 are organized as typical gammaCoVs (Coronaviridae family): 5′UTR-[ORFs 1a/1b encoding repl...

Background: Infectious bronchitis virus (IBV) is the etiological agent of an acute and highly contagious disease. Infectious bronchitis (IB) affects chicken of all ages and poses major economic loses to the poultry industry worldwide. The continuous evolution of the spike protein (S1) of IBV is responsible for the prevalence of many serotypes/genotypes around the world. Multipl...

Twelve genotypes of bread wheat, with four levels nitrogen (0, 75, 150, 225 kg N ha-1). were grown in split block design three replication growing season (2021), correlation, phenotypic and genotypic coefficient variation, heritability genetic advance estimated for (days 75% flowering, plant height, grain filling, yield, number spike/plant, spike length, weight, flag leaf area, biomes, protein ...

Bread wheat (Triticum aestivum) spike architecture is an important agronomic trait. The Q gene plays a key role in the domestication of bread wheat spike architecture. However, the regulatory mechanisms of Q expression and transcriptional activity remain largely unknown. In this study, we show that overexpression of bread wheat tae-miR172 caused a speltoid-like spike phenotype, reminiscent of t...

The present work has been conducted to study the impact of Zn (20 and 200 μM) or Ni (1 100 on growth, metabolic activities, osmotic pressure heavy metal wheat cultivar (cv. Gimiza 11) under salt stress conditions. Harvest index was significantly decreased by 75% at -0.3 MPa -1.2 53%. Length root, stem spike, leaf area were slightly reduced up -0.9 NaCl level, after that a significant reduction ...

Semliki Forest virus (SFV) particles are released from infected cells by budding of nucleocapsids through plasma membrane regions that are modified by virus spike proteins. The budding process was studied with recombinant SFV genomes which lacked the nucleocapsid protein gene or, alternatively, the spike genes. No subviral particles were released from cells which expressed only the nucleocapsid...
