for cassava mosaic begomoviruses CMBs- using grafting and whitefly inoculation was performed with local and improved cassava. The onset of symptom appearance and the evolution of Cassava mosaic disease CMD varied in function of genotypes and virus inoculation techniques used. Grafting position using cassava as scion or rootstock does not affect CMD display and evolution

  • 6. Modeling the Effects of Host Plant Resistance on Plant

    Indeed, durable host has been, and still is, the ultimate goal of pathologists, geneticists, and breeders alike e.g., Robinson, 1976 Bonman et al, 1992. The reasons for the central importance of this goal is that durable , a science-based, seed-borne technology, can comparatively be easily deployed, and does

  • Genome Wide Association Study of Seedling and Adult Plant

     · Leaf rust is an important disease, threatening wheat production annually. Identification of genes or QTLs for effective field could greatly enhance our ability to breed durably varieties. We applied a genome wide association study GWAS approach to identify genes or QTLs in 338 spring wheat breeding lines from public and private sectors that were

    All genotypes were further subjected to agroinoculation to confirm their resistance/susceptibility against MYMV using two different MYMV strains, namely VA 221 and VA 239. The results showed that only three genotypes, namely ML 1108, KMG 189 and SP 84, exhibited resistance to the VA 221 strain while 77 genotypes were found to be susceptible to strain VA 239

  • HIV Drug Resistance Testing, Genotype | Lab Tests Online

    Human immunodeficiency virus HIV genotypic antiretroviral drug testing evaluates the likelihood that the HIV strain infecting you is or has developed to one or more antiretroviral therapy ART drugs. The test analyzes the genes of the HIV strain infecting you to identify mutations that may cause the virus to be to ART

     · The World Health Organization has recommended use of molecular-based tests MTBDRplus and GeneXpert MTB/RIF to diagnose multidrug- tuberculosis in developing and high-burden countries. Both tests are based on detection of mutations in the Rifampin RIF -Determining Region of DNA-dependent RNA Polymerase gene rpoB. Such mutations are found in


    In the FHB , significant p < 0.05 differences for all traits were observed. A GWAS identified 16 SNPs associated with and susceptibility, ranging from -2.14 to 4.01%. Three DON-associated SNPs reduced toxin levels by 3.2, 2.1, and 1.5 ppm

     · In rice, totally one hundred and three were evaluated for against in three hot spot locations of Guyana. The experiments were conducted in spring and autumn seasons of 2015, 2016 and 2017. The modified upland blast nursery UBN method was adopted for screening blast resistance

  • Advancing host-plant resistance to Cotton leafroll dwarf

    The Cotton Leafroll Dwarf Virus, which causes Cotton Blue Disease CBD, is regarded as the second most damaging viral disease to commercial cotton worldwide. The recent discovery of CLRDV in the U.S. indicates this virus may pose a significant threat to the profitability of cotton production. Identifying durable sources of genetic and the underlying mechanisms that contribute to
