Staphylococcus aureus is a human commensal and opportunistic pathogen that causes devastating infections in a wide range of locations within the body. One of the defining characteristics of S. aureus is its ability to form clumps in the presence of soluble fibrinogen, which likely has a protective benefit and facilitates adhesion to host tissue. We have previously shown that the ArlRS two-compo...
این مطالعه، به منظور بررسی اطلاعات و کارایی نشانگر srap برای تخمین تنوع ژنتیک در 15 توده جعفری ایرانی صورت گرفته است. تکثیر مکانهای ژنی با استفاده از چهار ترکیب آغازگر srap انجام شد. بیشترین و کمترین تعداد باند های چندشکل تشکیل شده به ترتیب ترکیب آغازگر me2-em5 و me4-em1 بود. میانگین تعداد باندهای چندشکل به ازای هر ترکیب آغازگر 25/8 بود. تجزیه خوشه ای صفات مولکولی بر اساس ضریب تشابه جاکارد و ا...
Hemarthria compressa is one of the most important and widely utilized forage crops in south China, owing to its high forage yield and capability of adaptation to hot and humid conditions. We examined the population structure and genetic variation within and among 12 populations of H. compressa in south China using sequence-related amplified polymorphism (SRAP) markers. High genetic divers...
The Argania is an endemic genetic resource in Morocco holding an important ecological and socio-economical benefit. However, overgrazing and overharvesting lead to a serious downturn in the number of trees. To characterize genetic diversity within and among 24 populations, represented by 240 argan trees, four combinations of SRAP primers and eight combinations of REMAP primers were used. A tota...
ارزیابی تنوع ژنتیکی درون و بین گونه های اسپرس ایرانی (onobrychis vicifolia)با استفاده از نشانگر srap
اسپرس (onobrychis vicifolia, l) گیاهی چندساله و از خانواده بقولات بوده و ایران یکی از مهمترین مراکز تنوع جنس اسپرس به شمار می رود. با وجود اهمیت این گیاه در مراتع ایران، با این حال، تحقیقات بر روی توده های بومی اسپرس در کشور محدود و عمدتا به صورت منطقه ای صورت گرفته است. بررسی تنوع ژنتیکی توده های مختلف گیاه اسپرس می تواند در حفظ ذخایر ژرم پلاسم این گیاه و کمک به برنامه های اصلاحی موثر باشد. اس...
Sequence-related amplified polymorphism (SRAP) markers were used to investigate the genetic diversity among 30 populations of Toona ciliata Roem. sampled from the species’ distribution area in China. To analyze the polymorphism in the SRAP profiles, 1505 primer pairs were screened and 24 selected. A total of 656 SRAP bands ranging from 100 to 1500 bp were acquired, of these 505 bands (77%) were...
Erianthus arundinaceum is a wild relative species of sugarcane. The aim of this research was to demonstrate the feasibility of cDNA-SRAP for differential gene expression and to explore the molecular mechanism of drought resistance in E. arundinaceum. cDNA-SRAP technique, for the first time, was applied in the analysis of differential gene expression in E. arundinaceum under drought stress. In t...
We study field-monitoring applications in which sensors are deployed in large numbers and the sensing process is expensive. In such applications, nodes should use the minimum possible sensing ranges to prolong the “coverage time” of the network. We investigate how to determine such minimum ranges in a distributed fashion when the nodes are location-unaware. We develop a distributed protocol (SR...
BACKGROUND Foundations and public agencies commonly fund focused initiatives for individual grantees. These discrete, stand-alone initiatives can risk failure by being carried out in isolation. Fostering synergy among grantees' initiatives is one strategy proposed for promoting the success and impact of grant programs. We evaluate an explicit strategy to build synergy within the Robert Wood Joh...
Although Cynodon dactylon (C. dactylon) is widely distributed in China, information on its genetic diversity within the germplasm pool is limited. The objective of this study was to reveal the genetic variation and relationships of 430 C. dactylon accessions collected from 22 Chinese provinces using sequence-related amplified polymorphism (SRAP) markers. Fifteen primer pairs were used to amplif...
