Dioscorea polystachya Turcz. is the authentic herb Yam in Chinese traditional medicine. In medicinal marketplace, some related species are mislabeled as “Yams”, such D. alata L., exalata C.T. Ting & M.C. Chang, persimili Prain et Burkill, fordii Burkill and japonica Thunb. To determine genetic relationships among these develop a rapid accurate method for identification, Inter Simple Sequence Re...

Dendrobium officinale is an endangered orchid from southeast Asia that is known for its medicinal properties in traditional Chinese medicine. We constructed an integrated genetic linkage map of an F(1) population derived from an interspecific cross between D. officinale and D. aduncum (both, 2n = 38), using expressed sequence tag-simple sequence repeats (EST-SSR) and sequence-related amplified ...

Background: The dried sclerotium of medicinal fungus Polyporus umbellatus (Pers.) Fries has many pharmacological functions such as diuretic and anticancer activity, in which high-content polysaccharides may play an important role. However, RNA isolation is difficult in filamentous fungi and lacking in P. umbellatus. Results: Five methods for RNA extraction from five strains collected from four ...

The genus Stachys is one of the largest in Lamiaceae family. Representatives are among most ancient medicinal plants used ethnomedicine. Balkan endemic species S. thracica , bulgarica and scardica included Red Data Book Bulgaria due to their endangered status scarcely studied. aim present work was examine genetic these three during process ex situ conservation. To gain information about taxonom...

Yellow rust (stripe rust), caused by Puccinia striiformis f. sp. tritici, is one of the most destructive foliar diseases of wheat in Egypt and worldwide. In order to identify wheat genotypes resistant to yellow rust and develop molecular markers associated with the resistance, fifty F8 recombinant inbred lines (RILs) derived from a cross between resistant and susceptible bread wheat landraces w...

The aim of this study was to analyze the expectorant, antitussive and antiasthmatic effects of asterosaponin from Luidia quinaria through secretion of phenol red from mouse tracheas, frequency of cough caused by ammonia in mice and asthma induced by histamine in guinea pig, respectively. Results showed that asterosaponin extracted from L. quinaria at doses of 20 mg/kg and 40 mg/kg could signifi...

The blunt snout bream (Megalobrama amblycephala) is an important freshwater aquaculture fish throughout China. Because of widespread introductions of this species to many regions, the genetic diversity of wild and natural populations is now threatened. In the present study, SRAP (sequence-related amplified polymorphism) markers were used to assess genetic diversity of blunt snout bream. Three n...

Cotton is an important cash crop. Mining for quantitative trait loci related to yield and fiber quality traits using association analysis has many advantages for cotton research. In this study, 170 simple sequence repeats (SSRs) and 258 sequence-related amplified polymorphisms (SRAPs) were used to analyze the association of 3 yield component traits and 5 fiber quality traits of 55 Gossypium bar...

An F2 population derived from a cross between apetalous line' APT02 'and normal petalled cultivar 'ZS NO.4' was used for molecular marker searching and chromosomal mapping of the gene(s) controlling petal-loss trait in Brassica napus. Twenty pairs of AFLP primers and 170 pairs of SRAP primers were selected and screened from two parents. In further selection through bulked segregant analysis (BS...

انار یکی از قدیمی ترین گونه های گیاهی شناخته شده است که خاستگاه آن را به ایران و برخی از مناطق اطراف آن نسبت می دهند. تفکیک ارقام انار عمدتاً بر اساس خصوصیات مورفولوژیک مانند رنگ پوست وآریل میوه انجام می گیرد که تحت تاثیر اکوسیستم محل کشت است. برای گیاهانی از این قبیل که در گستره وسیع جغرافیایی کشت می شوند وجود چند نام برای یک ژنوتیپ در مناطق مختلف شایع است. استفاده از نشانگر های مولکولی به عنوا...
