Residual gene resistance using the crown rust of oats pathosystem
Residual gene resistance has been described as the effect of race-specific resistance genes in the host plant when the host is inoculated with a pathogen lacking the corresponding avirulence genes. Pyramiding resistance genes may produce durable, effective resistance against many pathogen races. …

Role of SABP2 in Tobacco Non-Host Resistance.
… their <em>avirulent</em> (<em>avr</em>) genes by <em>Resistant</em> (<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. …

Studies on the Gecko P521 Cone-Type Pigment
… used to identify components of the plant disease resistance pathway. The availability of the dnd mutants may facilitate further study of the control of HR cell death, gene-for-gene resistance, and broad spectrum disease resistance in plants.

Functional Dissection of Arabidopsis Thaliana Resistance Gene RPS2
… RPS2 that modify expression and strength of the resistance response. Further characterization and cloning of the RPS2- and RPM1-interacting loci, conjoined with functional analysis of RPS2 protein domains such as the LRRs and the NBS, should provide valuable insights into the structure, molecular …

"Physiological and Molecular Analysis of Dnd ""Defense, No Death"" Mutants of Arabidopsis"
… of the molecular mechanisms of plant disease resistance an economically important task. Gene-for-gene resistance mediated by plant R genes and pathogen avr genes has long been associated with the hypersensitive response (HR). Previously, Arabidopsis thaliana ""defense, no death"" (dnd) mutants …

Combining and mapping QTL for fusarium head blight (FHB) resistance in wheat
… and semi-humid regions around the world. Single gene resistance to FHB in wheat provides only partial resistance and also the disease severity is highly influenced by environment. Consequently multiple genes are required for effective resistance. Our hypothesis is that identifying DNA markers for …

Qualitative Resistance to Exserohilum Turcicum Race 2 in Maize (Corn, Genetics)
… over 15 years by qualitative and quantitative resistance. In 1979 a new race of the fungus (race 2) was found in the U.S. Corn Belt. This study was designed to evaluate currently available sources of qualitative resistance for their effectiveness against race 2. The gene Ht(,1) confers a …

Mechanism of Resistance in Common Ragweed to PPO-inhibiting Herbicides
… Only four weed species have been documented with resistance to this herbicide class. Waterhemp was the first weed species documented with PPO-resistance, which was due to a single codon deletion in a dual-targeting gene known as PPX2L. Common ragweed, from Delaware, was the third documented weed …

The Utilization of the Hmg2 Inducible Promoter to Genetically Engineer Parasite Resistance in Tobacco
… objective of this research was to engineer resistance to the cyst nematode and Egyptian broomrape by expressing genes encoding parasite specific toxins under the control of parasite-responsive promoters using tobacco (Nicotiana tabacum L. cv. Xanthi). For nematode resistance, an anti-feeding …

Barley pathogens in Iceland: Identification, virulence and genetic structure of major barley pathogens in Iceland
… of scald and net blotch, respectively. The genetic structure of the Icelandic R. secalis population was studied using thirteen microsatellite markers and results compared to six European R. secalis populations. The genetic structure of P. teres was examined with four AFLP markers and …

The role of transcription factors in somatic cell nuclear reprogramming by eggs and oocytes
… regulated similar sets of pluripotency genes in mouse embryonic fibroblasts (MEFs). Pioneer factor mFoxA1 could not up-regulate most pluripotency genes and their binding targets of neurogenic genes in MEFs while pioneer factors are proposed to bind to their targets even if they may …

Insight into the Molecular Mechanisms of the Interactions and Functions of the Wheat Powdery Mildew AVRPM3 and SVRPM3$^t{a1/f1}$ Effectors and the Wheat NLR-Type Immune Receptor PM3b
… graminis f. sp. tritici (Bgt) and race-specific resistance can be conferred by the Pm3 allelic series. These genes encode a coiled-coil (CC) nucleotide-binding leucine-rich repeat protein (NLR) that acts as an immune receptor and recognize sequence diverse AVRPM3 effectors having a predicted …
