Genetic diversity within and among aecia of the wheat rust fungus Puccinia striiformis on the alternate host Berberis vulgaris

An isolate of the fungus Puccinia striiformis, causing yellow (stripe) rust on cereals and grasses, was selfed on the alternate (sexual) host, Berberis vulgaris. This enabled us to investigate genetic variability of progeny isolates within and among aecia. Nine aecial clusters each consisting of an aecium (single aecial cup) and nine clusters containing multiple aecial cups...

A special issue on Fusarium head blight and wheat blast

Fusarium head blight (FHB, or scab) of wheat and barley and wheat blast (or brusone) are two major head diseases with devastating impact on yield and grain quality. These fungal diseases emerged as a major threat to global food security and human health over three decades ago. Since the early 1990s, FHB, caused mainly by Fusarium graminearum sensu lato,...

Genomic and pedigree-based prediction for leaf, stem, and stripe rust resistance in wheat

The unceasing plant-pathogen arms race and ephemeral nature of some rust resistance genes have been challenging for wheat (Triticum aestivum L.) breeding programs and farmers. Hence, it is important to devise strategies for effective evaluation and exploitation of quantitative rust resistance. One promising approach that could accelerate gain from selection...

Physical mapping of DNA markers linked to stem rust resistance gene Sr47 in durum wheat

In durum wheat (Triticum turgidum subsp. durum), the gene Sr47 derived from Aegilopsspeltoides conditions resistance to race TTKSK (Ug99) of the stem rust pathogen (Puccinia...

Discovery and characterization of two new stem rust resistance genes in Aegilops sharonensis

Stem rust is one of the most important diseases of wheat in the world. When single stem rust resistance (Sr) genes are deployed in wheat, they are often rapidly overcome by the pathogen. To this end, we initiated a search for novel sources of resistance in diverse wheat relatives and identified the wild goatgrass species ...

Microsatellite markers for the Triticum timopheevi-derived leaf rust resistance gene Lr18 on wheat 5BL chromosome

Leaf rust, caused by Puccinia triticina, is a common wheat disease worldwide. Developing resistant cultivars through deploying new or pyramiding resistance genes in a suitable line, is the most effective approach to control this disease. However, to stack genes in a genotype, efficient and reliable markers are required. In the present study, F2 plants and their corresponding...

Vulnerability of Barley to African Pathotypes of Puccinia graminis f.sp.tritici and Sources of Resistance

The emergence of widely virulent pathotypes (e.g., TTKSK in the Ug99 race group) of the stem rust pathogen (Puccinia graminis f.sp. tritici) in Africa threatens wheat production on a global scale. Although intensive research efforts have been advanced to address this threat in wheat, few studies have been conducted on barley, even though pathotypes such as TTKSK are known to attack the crop....

Genetic analysis of resistance to stripe rust in some Iranian bread wheat cultivars and elite lines

Stripe rust is the most important disease of wheat in many wheat growing areas in Iran. Good knowledge of the genetic basis of resistance to stripe rust in commercial bread wheat cultivars and selected elite lines is an important objective in wheat breeding programs. This study aimed to identify resistance genes and modes of inheritance of stripe rust resistance in recently released Iranian...

First Report of Virulence to Sr25 in Race TKTTF of Puccinia graminis f. sp. tritici Causing Stem Rust on Wheat

Puccinia graminis f. sp. tritici (Pgt) race TKTTF was reported as the dominant race in the wheat stem rust epidemics in Ethiopia during 2014–15 (Olivera et al. 2015). The race and variants hereof have also been recorded elsewhere in Africa, the Middle East, and Europe (...
