Fusarium head blight (FHB), leaf rust, and stem rust are the most destructive fungal diseases in current world wheat production. The diploid wheatgrass, Thinopyrum elongatum (Host) Dewey (2n = 2x = 14, EE) is an excellent source of disease resistance genes. Two new Triticum-Secale-Thinopyrum trigeneric hybrids were derived from a cross between a hexaploid triticale (X Triticosecale Wittmack, 2n...

Rust, as being a systems programming language, offers memory safety with zero cost and without any runtime penalty unlike other languages like C, C++ or Cyclone. System programming languages are mainly used for low level tasks such as design of operating system components, web browsers, game engines and time critical missions like signal processing. Main disadvantages of the existing systems la...

To study the molecular basis of biotrophic nutrient uptake by plant parasitic rust fungi, the gene (Uf-PMA1) encoding the plasma membrane H(+)-ATPase from Uromyces fabae was isolated. Uf-PMA1 exists probably as a single gene. However, two nearly identical sequences were identified; the similarity apparently is due to two Uf-PMA1 alleles in the dikaryotic hyphae. Multiple Uf-PMA1 transcripts wer...

Managing multiple forest insect pests and diseases is challenging. For example, in eastern white pine ( Pinus strobus ) stands whereas partial shading high seedling density encouraged to reduce damage by blister rust Cronartium ribicola weevil Pissodes strobi ), dense conditions the understory may increase foliar such as brown spot needle blight Lecanosticta acicola Caliciopsis canker pinea ). ...

63 Bean rust is a devastating disease of common bean in the Americas and Africa. The historically 64 important Ur-3 gene confers resistance to many races of the highly variable bean rust pathogen 65 that overcome all known rust resistance genes. Existing molecular markers tagging Ur-3 for use 66 in marker assisted selection produce false results. We described here the fine mapping of Ur-3 67 fo...

Stripe rust caused by Puccinia striiformis f. sp. tritici is most important and devastating disease of wheat worldwide, which affects the grain yields, quality and nutrition. To elucidate, the genetic basis of resistance, a mapping population of recombinant inbred lines was developed from a cross between resistant Cappelle-Desprez and susceptible cultivar PBW343 using single-seed descent. Varie...

Experienced programmers often need to use online resources to pick up new programming languages. However, we lack a comprehensive understanding of which resources programmers find most valuable and utilize most often. In this paper, we study how experienced programmers learn Rust, a systems programming language with comprehensive documentation, extensive example code, an active online community...

Glyphosate is a broad-spectrum herbicide used for the control of weeds in glyphosate-resistant crops. Glyphosate inhibits 5-enolpyruvyl shikimate 3-phosphate synthase, a key enzyme in the synthesis of aromatic amino acids in plants, fungi, and bacteria. Studies with glyphosate-resistant wheat have shown that glyphosate provided both preventive and curative activities against Puccinia striiformi...

The obligate bitrophic fungus Puccinia striiformis f. sp. tritici (Pst) causes stripe (yellow) rust on wheat worldwide. Here, we report a novel fungal strain able to hyperparasitize Pst. The strain was isolated from gray-colored rust pustules, and was identified as Alternaria alternata (Fr.: Fr.) keissler based on a combination of morphological characteristics and multi-locus (ITS, GAPDH, and R...

The introduction of nonnative pathogens is altering the scale, magnitude, and persistence of forest disturbance regimes in the western United States. In the high-altitude whitebark pine (Pinus albicaulis) forests of the Greater Yellowstone Ecosystem (GYE), white pine blister rust (Cronartium ribicola) is an introduced fungal pathogen that is now the principal cause of tree mortality in many loc...
