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 ...

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...
