The rust fungi (order: Pucciniales) are a group of widely distributed fungal plant pathogens, which can infect representatives of all vascular plant groups. Rust diseases significantly impact several crop species and considerable research focuses on understanding the basis of host specificity and nonhost resistance. Like many pathogens, rust fungi vary considerably in the number of hosts they c...

Wheat leaf rust, caused by Puccinia triticina Eriks., is of worldwide concern for wheat producers. The disease has been an annual problem for Canadian wheat producers since the early days of wheat cultivation in the 1800s, and research focused on combating this disease began in the early 1900s. Significant progress was made towards understanding the epidemiology of wheat leaf rust and developin...

In the present study, two species of rosaceous rust fungi are reported from Iran. Ochropsora ariae is newly reported for Iranian rust mycobiota. This is the first report of a member of the genus Ochropsora from Iran. Kuehneola uredinis is reported for the second time from Iran since its first report in 1958 under the name K. albida. Pyrus boissieriana</em...

Based on the floristic study of rust fungus flora (Uredinales) ofGolestan National Park, located in the Northeast of Iran, 68 rust taxa were recognized. Of these, one subspecies and five species viz. Phragmidium sanguisorbae subsp. mediterraneum on Sanguiosorba minor, Puccinia difformis on Galium aparine, P. jasmini on Jasminum fruticans, P. rhylismoides on Thalictrum isopyroides, Uromyces mogi...

Daylilies (Hemerocallis spp., Liliaceae) are one of the most important cultivated perennial plants in the United States. Daylily rust, a serious disease caused by Puccinia hemerocallidis Thüm., was observed in Georgia in August 2000 (14) and was found in at least 20 other states and in Costa Rica in 2001. It was originally described from Russia, reported throughout the Japanese archipelago, and...

Rust diseases are the major cause of low yield of wheat in Pakistan. Wheat breeders all over the world as well as in Pakistan are deriving rust resistance genes from alien species like Triticum ventricosum and introducing them in common wheat (Triticum aestivum). One such example is the introgression of rust resistance gene cluster Lr37-Sr38-Yr17 derived from T. ventricosum chromosome 2NS into ...

ABSTRACT Leaf and stripe rusts, caused by Puccinia triticina and P. striiformis, respectively, are globally important fungal diseases of wheat that cause significant annual yield losses. A gene that confers slow rusting resistance to leaf rust, designated as Lr46, has recently been located on wheat chromosome 1B. The objectives of our study were to establish the precise genomic location of gene...

A web-based prediction system for wheat stripe rust was developed based on B/S (Browser/Server) mode in this study. Some existing prediction models of wheat stripe rust were collected, analyzed and then stored in SQL Server 2005 database according to certain rules. All these models could be called through this web-based system and used to predict wheat stripe rust. Meanwhile, Using multiple reg...

Ribosome profiling (Ribo-seq), a promising technology for exploring ribosome decoding rates, is characterized by the presence of infrequent high peaks in ribosome footprint density and by long alignment gaps. Here, to reduce the impact of data heterogeneity we introduce a simple normalization method, Ribo-seq Unit Step Transformation (RUST). RUST is robust and outperforms other normalization te...
