Role of SABP2 in Tobacco Non-Host Resistance.
… (<em>R</em>) genes leading to <em>R</em>-gene resistance or host resistance. Another form of innate immunity is non-host resistance that is exhibited by a given plant species to most strains of a microbial species. <em>R</em>-gene resistance activates salicylic acid (SA) that is synthesized …

Genetic factors that determine host resistance to bacterial infection
Antibiotic resistance is one of the major challenges that we face today. Not only in a medical sense, but also for a country’s national security, as the use of a bioweapon is an ever increasing concern. To help combat these threats, understanding how bacteria interact with their host could be a key …

Molecular genetic analysis of host resistance to soybean mosaic virus
… diseases in soybean (Glycine max L. Merr.). Host resistance to SMV conferred by a single dominant gene, Rsvl, was studied as a model to gain insights of plant virus resistance genes, and to facilitate the breeding of resistant cultivars. DNA restriction fragment length polymorphisms (RFLPs) …

Management Strategies for Hop Downy Mildew Utilizing Fungicides and Host Resistance
… of hops requires the use of fungicides and host resistance to retain high overall yields and quality characteristics that brewers are satisfied with. The primary objectives of this research were to determine effective fungicidal compounds that can be used to control hop downy mildew (caused …

Understanding the Evolution of Emerging Bacterial Pathogens in Response to Host Resistance
Understanding the evolution of parasites and hosts following a host-shit event is increasingly recognised as being of great importance to public health and the clinical/veterinary sciences in predicting the behaviour and evolutionary consequences of emerging infectious diseases. Microbial …

Soybean-Pythium pathosystem: Search for host resistance and interaction with Fusarium species
… together from diseased soybean seedlings. Host resistance as a strategy to manage multiple pathogens has only briefly been explored in soybean and the interaction between these pathogens is unclear. To better understand the soybean-Pythium pathosystem, lab and growth chamber assays were …

Investigating the role of downy mildew effectors in host resistance and susceptibility
Through specialised structures called haustoria, filamentous eukaryotic plant pathogens such as rusts and mildews can deliver “effector” proteins directly into plant cells in order to manipulate specific defence responses and processes. Hyaloperonospora arabidopsidis (Hpa) is a haustorium-producing …

Studies on red crown rot of soybean: incidence in Illinois, fungicide seed treatments, and host resistance
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2022-11-14 without embargo terms

Epidemiology of Phomopsis Seed Decay of Soybeans: Infection Progress and the Effects of Weather and Host Resistance
Phomopsis seed decay of soybeans (Glycine max L.), caused by the fungi Diaporthe phaseolorum (Cke. & Ell.) Sacc. var. sojae Wehm. and an unidentified Phomopsis sp., reduces the germination, vigor, and quality of seeds grown in seasons with warm, wet weather near harvest. The establishment of …

Nterleukin-4 responsive dendritic, macrophage/neutrophil cells are dispensable for host resistance against Leishmania Mexicana infection in mice
… does not contribute to the susceptibility or resistance to BALB/c mice to infection with L. mexicana.

Evaluation of Host Resistance and the Utilization of Organic Amendments to Manage Macrophomina Crown Rot of Strawberry in California
… can cause extensive plant decline and mortality. Host resistance will be a critical tool for managing this disease and guiding breeding programs in the post methyl bromide era. Evaluation of host resistance in strawberry germplasm to <em>M. phaseolina</em> was evaluated through phenotypic …

IDENTIFYING HIGHLY CONSERVED PATHOGENICITY GENES IN CHESTNUT BLIGHT AND POWDERY MILDEW FUNGI AS TARGETS FOR NOVEL FORMS OF HOST RESISTANCE
… TG4 appears to be a promising target for host-induced gene silencing (HIGS) in transgenic American chestnut. The use of homologues from genetically tractable species like Cp can help overcome the obstacles to performing reverse genetics on intractable, biotrophic fungi such as Gc. …

Inheritance of Resistance in Dent Corn to Wheat Streak Mosaic Virus and Erwinia Stewartii
Host resistance is the primary means of controlling diseases of field crops, such as dent corn (Zea mays L.). Knowledge of the inheritance of resistance facilitates its incorporation into agronomically desirable germplasm. Relatively little is known about the inheritance of resistance in corn

Towards an understanding of symbiont natural history through studies of crayfish and their annelid associates
… throughout North America, Europe, and Asia host assemblages of obligate ectosymbiotic annelid worms called branchiobdellidans. The work presented here is a detailed experimental and observational study of the ecological interactions between crayfish and their worms. In a comprehensive …

Elucidating the molecular genetics of host and nonhost resistance in barley to stripe rust
… encounter. As such, they are described as nonhosts. Nonhost resistance is often conceptualised as a qualitative separation from host resistance. Classification into these two states is generally facile, as they fail to fully describe the range of states that exist in the transition from host …

Resistance to anthracnose leaf blight in sorghum
… Colletotrichum sublineola. The pathogen is host specific and survives on seeds, mycelium, conidia, and soil. There are three forms of the disease: leaf blight, stalk rot, and panicle and grain rot. Anthracnose leaf blight is usually encountered 30-40 days after planting and is responsible …
