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]...

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 ...

Lentil, as an economical source of protein, minerals and vitamins, plays important role in nutritional security of the common man. Grown mainly in West Asia, North Africa (WANA) region and South Asia, it suffers from several biotic stresses such as wilt, rust, blight and broomrape. Lentil rust caused by autoecious fungus Uromyces viciae fabae (Pers.) Schroet is a serious lentil disease in Alger...

Eight cyperaceous Puccinia and Uromyces, viz. P. cariciola, P. conclusa, P. cyperi, P. eriophori, P. scirpi and Uromyces lineolatus subsp. lineolalus are reported as new to Iran. The uredinial stage of P. dioicae is reported as a new stage for this rust in Iran. Hosts new to P. eriophori are also given. Included is a key to the cyperaceous rust species in Iran.

Entada simplicata, formerly recognized as a variety of E. polystachya, is reinterpreted as a distinct legume species, based on consistent differences regarding their leaves (number of pairs and width of leaflets), and fruits (mesocarp presence, stipe and funiculus length). Illustrations and a distribution map are provided for E. simplicata, which is endemic to Roraima State, northern Amazonia, ...

Rust diseases remain a significant threat to the production of most cereals including wheat. New sources of resistance are continually sought by breeders to combat the emergence of new pathogen races. Rice is atypical in that it is an intensively grown cereal with no known rust pathogen. The resistance of rice to cereal rust diseases is referred to as nonhost resistance (NHR), a resistance mech...

rust caused by phakopsora pachyrhizi syd. is a major constraint to soybean product in asia. early detection and possibilities of controlling plant diseases by the integration of several image processing methods has been the subject of extensive research. the main contribution of this paper is to present different methodologies for quantitatively detecting soybean rust at each stage of disease d...
