The analysis of the available bibliographic data on influence silicon and its compounds physiological processes in plants was carried out. purpose work to determine effect organosilicon growth regulator Energia-M concentrations 10, 50, 80 mg/l productivity early-ripening potato Zhukovsky cultivar grown grey forest soils a greenhouse. Low 50 did not activity significantly. concentration increase...
آهن یک ریز مغزی ضروری است اما علیرغم این ویژگی دارای مشکلاتی همچون ایجاد سمیت در غلظت های بالا و عدم در دسترس بودن برای میکروارگانیسم ها ی هوازی می باشد . باکتری اشرشیاکولی با بکارگیری حداقل دو نوع پروتئین ذخیره کننده آهن با این مشکلات مقابله می کند که این پروتئین ها عبارتند از : ftna ( فریتین ) که پروتئین اصلی ذخیره آهن است و باکتریوفریتین حاوی هم ( bfr ) که نقش آن بطور کامل مشخص نشده است . یک...
To study effects of salicylic acid (SA) treatments (0, 0.5, 1 and 2 mM) in two forms of seed priming (for 24 h) and spraying on seedling at 4-6 leaf stage an experiment was conducted on periwinkle (Catharanthus roseus Don.) with and without exposure to a mild cold stress of 8 °C (for 32 h). Seeds were sown in trays containing peat-based substrate (with 20% sandy loam field soil). Transplants of...
Purpose. To improve the technology of grain sorghum cultivation by detecting influence microfertilizers and plant growth regulators on its productivity.
 Methods. The research was conducted at field Bila Tserkva National Agrarian University, which is located in zone unstable humidification Right-Bank Forest-Steppe, years 2019–2021. Grain hybrids ‘Brigga’ ‘Yutami’ were used for experiment.&...
background:the zinc-finger x linked (zfx) gene encodes a transcription factor that acts as a regulator of self-renewal of stem cells. due to the role of zfx in cell growth, understanding zfx protein-protein interactions helps to clarify its proper biological functions in signaling pathways. the aim of this study is to define zfx protein-protein interactions and the role of zfx in cell growth. m...
controller design and optimization problems, with more than one objective, are referred as multiple objectives or multiple attributed problems. in this paper, a novel method is proposed for designing optimum pid controller that is called genetic multiple attributed decision making method (gmadm). this method is newer than the previous methods and in this paper some options are considered that h...
The human opportunistic pathogen Candida albicans undergoes a reversible morphological transition between the yeast and hyphal states in response to a variety of signals. One such environmental trigger is growth within a semisolid matrix such as agar medium. This growth condition is of interest because it may mimic the growth of C. albicans in contact with host tissue during infection. During g...
background: the current study investigated the possible role of the cell cycle regulator, cyclin-dependent kinases regulatory subunit-2; the angiogenic factor, plateletderived endothelial cell growth factor; and the cell adhesive molecule, neural cadherin, as prognostic factors in schistosomal and non-schistosomal-associated urothelial carcinomas. we also investigated the possible correlation b...
Genetic circuits in bacteria are intimately coupled to the cellular growth rate as many parameters of gene expression are growth-rate dependent. Growth-rate dependence can be particularly pronounced for genes on plasmids; therefore the native regulatory systems of a plasmid such as its replication control system are characterized by growth-rate dependent parameters and regulator concentrations....
to survey the effects of nutritional and growth regulator components on adverse effects of recent consecutive droughts, an experiment was conducted on uniform grape trees (vitisviniferal.clv.'khalili') in bavanat and shiraz (akbar-abad) regions in 2010- 2011.trial was arranged in a randomized complete blockdesign (rcbd), with three replication and five trees per each plot. experimental treatmen...
