Stripe rust, caused by Puccinia striiformis Westend. f. sp. tritici Erikss., is a severe foliar disease of common wheat (Triticum aestivum L.) worldwide. Use of adult-plant resistance (APR) is an efficient approach to provide long-term protection of crops from the disease. The German spring wheat cultivar Naxos showed a high level of APR to stripe rust in(More)
Italian common wheat cultivars Libellula and Strampelli, grown for over three decades in Gansu province of China, have shown effective resistance to stripe rust. To elucidate the genetic basis of the resistance, F(3) populations were developed from crosses between the two cultivars and susceptible Chinese wheat cultivar Huixianhong. The F(3) lines were(More)
ABSTRACT Stripe rust, caused by Puccinia striiformis f. sp. tritici, is one of the most widespread and destructive wheat diseases worldwide. Growing resistant cultivars with adult-plant resistance (APR) is an effective approach for the control of the disease. In this study, 540 simple sequence repeat markers were screened to map quantitative trait loci(More)
—This paper studies optical communications using sub-carrier phase shift keying (PSK) intensity modulation through atmospheric turbulence channels. The bit error rate (BER) is derived for optical communication systems employing either on/off key (OOK) or subcarrier PSK intensity modulation. It is shown that at BER = 10 −6 and a scintillation level of σ =(More)
OBJECTIVE To investigate the predictors that reduced the survival time on HIV positive TB patients during their first year's anti-TB therapy. METHODS A retrospective study was conducted to review 519 TB/HIV co-infection patients from an Internet based TB surveillance system. We collected information of demography, HIV status, CD4+ lymphocytes count,(More)
