Abstract Triticum monococcum L. and T. boeoticum L., diploid wild relatives of bread wheat ( aestivum L.), possess resistance to leaf rust (also known as brown rust) caused by Puccinia triticina Eriks. Haustorium formation-based mechanisms (i.e. pre-haustorial post-haustorial resistance) have been studied reported in various accessions. In the present study, mechanism accessions was using confo...
Abstract Applying the difference-in-difference (DID) estimation procedure, this study quantifies wheat blast ( Magnaporthe oryzae pathotype Triticum) induced losses in yield, quantity of sold, consumed, or stored, as well grain value Bangladesh 2016 following a disease outbreak that affected over 15,000 ha. Estimates show blast-induced yield loss was 540 kg ha −1 on average for households blast...
Singh, R. P., Bechere, E., and Abdalla, 0. 1992. Genetic analysis of resistance to stem rust in ten durum wheats. Phytopathology 82:919-922. Durum wheat (Triticum turgidum L.) cultivars derived from CIMMYT present in Mexicali 75, Diver, Somorguho, and Morus together with (International Maize and Wheat Improvement Center) germplasm are an unidentified gene, SrC, and in Altar 84, Carcomun, Totanu...
To determine if fatal infections caused by different highly virulent influenza A viruses share the same pathogenesis, we compared 2 different influenza A virus subtypes, H1N1 and H5N1. The subtypes, which had shown no pathogenicity in laboratory mice, were forced to evolve by serial passaging. Although both adapted viruses evoked diffuse alveolar damage and showed a similar 50% mouse lethal dos...
Understanding the molecular parameters that regulate cross-species transmission and host adaptation of potential pathogens is crucial to control emerging infectious disease. Although microbial pathotype diversity is conventionally associated with gene gain or loss, the role of pathoadaptive nonsynonymous single-nucleotide polymorphisms (nsSNPs) has not been systematically evaluated. Here, our g...
