We developed an evolutionary relevant model system, barley-Puccinia [corrected] rust fungi, to study the inheritance and specificity of plant factors that determine to what extent innate nonhost immunity can be suppressed. A mapping population was developed from a cross between an experimental barley line (SusPtrit) [corrected] with exceptional susceptibility to several heterologous [corrected]...

The Volga region is one of the main grain-producing regions Russia. Wheat stem rust caused by Puccinia graminis f. sp. tritici among most destructive fungal diseases wheat. Recently, its harmfulness has increased in region. In this regard, an analysis resistance and diversity Sr genes Russian wheat cultivars necessary. work, 126 (including 23 durum 103 bread cultivars) approved for use were eva...

Rust is a newly designed systems programming language that aims at safety. However, as a systems language, Rust must be able to manipulate rawmemory and interact with native C codes freely. In this project, we demonstrate how the use of unsafe keyword can potentially undermine the security guarantees of Rust. Specifically, we provideworking demonstrations to show that in some circumstances, vul...

-Eastern cottonwood clones originating from 36 young natural stands along the Mississippi River from Memphis, Tennessee, to Baton Rouge, Louisiana, were evaluated in a nursery near Greenville, Mississippi for resi~tance to Melampsora rust. In general, the northern sources had more rust and were more variable in rust susceptibility than the southern sources. Eleven percent of the clones from the...

Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is one of the most destructive diseases of wheat (Triticum aestivum L.) worldwide. Agropyron cristatum (L.) Gaertn. (2n = 28, PPPP), one of the wild relatives of wheat, exhibits resistance to stripe rust. In this study, wheat-A. cristatum 6P disomic addition line 4844-12 also exhibited resistance to stripe rust. To identify the s...

Background Puccinia psidii causes rust disease on many host species in the Myrtaceae [1]. First reported in 1884 on guava in Southern Brazil [2], the rust has since been detected on several myrtaceous in South America, Central America, Caribbean, Mexico, USA: in Florida, California, and Hawaii. More recently, P. psidii was reported in Japan infecting M. polymorpha[3]. Of special note is that a ...

a study was conducted to assess the durable resistance in a near isogenic line of spring wheat (triticum aestivalis l.), possessing resistance gene yr-18 to some isolates (race specific resistance) of stripe rust (puccinia striiformis f. sp. tritici), namely thatcher yr-18 and durable resistance of an cultivar of spring wheat to all isolates of stripe rust (race non- specific resistance), namel...
