به منظور بررسی تاثیر پرتودهی بذر با اشعه گاما و پلی اتیلن گلیکول 6000 بر خصوصیات جوانه زنی و برخی پارامترهای فیزیولوژیک دو گونه secale montanum guss.و (l.) gaertn agropyron cristatum ، آزمایشی به صورت فاکتوریل در قالب طرح کاملاً تصادفی انجام شد. بذرهای گونه های مورد تحقیق تحت تابش پرتو گاما با سطوح 0، 20، 40، 60، 100 و 150 گری و محلول پلی اتیلن گلیکول 6000 در سطوح 0، 4- و 8- بار در سه تکرار در ش...
Several examples of natural mutants in the grass family were presented. All appeared as changes in inflorescence structure. In mutated plants chasmogamy was restricted due to anomalous lodicules or compactness of ears. A rare glumeless mutation in Agropyron pectiniforme reduced the level of assimilation in the ear. All mutations appear as unfavorable in natural populations.
The hypotheses about the origin of the primitive amniotic tarsus are very speculative. Early studies argued that the origin of the astragalus, one of the largest proximal bones in the tarsus of basal amniotes, was produced by either the fusion of two, three, or even four of the original tarsal bones, the intermedium, the tibiale and the proximal centralia (c4 and c3), or that the intermedium al...
Near infrared reflectance spectroscopy (NIRS) has recently become a potentially valuable and reliable tool for analyses of plant samples in forage-breeding programs. The success of NIRS is dependent on identification of appropriate and reliable selection criteria and development of reliable calibration. The objectives of this study were to develop and compare NIRS analysis equations for the in ...
background: thymus is a widely used medicinal plant in food and pharmaceutical industries. among different species of thymus, t. vulgaris is used more than other species in therapeutic dosage forms. objective: this study was conducted to differentiate various thymus species by tlc fingerprint. methods: in order to identify and differentiate various species of thymus, tlc fingerprints of essenti...
Genetic studies of Ochrobactrum anthropi are hindered by the lack of a suitable gene expression system. We constructed a set of vectors containing several promoters and a His tag fusion in the N terminus to facilitate protein detection and purification. The new vectors should significantly enhance the genetic manipulation and characterization of O. anthropi.
Ochrobactrum anthropi is an occasional cause of nosocomial infections; however, interest in the organism lies in its phylogenetic proximity to the genus Brucella. Here, we present the 4.9-Mb finished genome of Ochrobactrum anthropi ATCC 49687, most commonly used as an exclusionary reference organism.
در بازنگری جنس GaertnerAgropyron در ایران، که بر اساس مطالعه نمونه های هرباریومی و جمع آوریهای جدید و مشاهدات صحرائی صورت گرفت، یک واریته جدید (Agropyron cristatum subsp. pectinatum var. minor) و یک زیر گونه جدید (Agropyron cristatum subsp. hamadanicum) از غرب ایران (همدان)، معرفی می‌شود. واریته جدید با داشتن ساقه‌های کوتاهتر، سنبله ظریف و گلوم و لمای کوتاهتر، از Agropyron cristatum subsp. pect...
We describe the first clinical case report of infective endocarditis related to Ochrobactrum intermedium infection. The case involved a 23-year-old man receiving dialysis via an internal jugular long-term haemodialysis catheter. He improved with a prolonged course of meropenem and minocycline. Ochrobactrum spp. are recognized as rare emerging opportunistic pathogens.
transpiration, as one of the components of hydrological cycle, has not been paid enough attention yet, while it is necessary for sound utilization of rangelands, mostly located in the arid and semiarid regions. the comparison of the different kinds of rangelands species in terms of transpiration rates provides range managers the required information to achieve optimal forage production for a gi...
