Open AccessPathogenicity of Puccinia porri on Allium in South Africa
Allium crops are commonly grown in South Africa and harvested as either fresh produce for the domestic and export markets or as seed. Apart from occasional outbreaks on garlic, rust is problematic as a cosmetic d...

Identification and introgression of a novel leaf rust resistance gene from Thinopyrum intermedium chromosome 7Js into wheat
A novel leaf rust resistance locus located on a terminal segment (0–69.29 Mb) of Thinopyrum intermedium chromosome arm 7JsS has been introduced into wheat genome for disease resistance breeding.

Open AccessAccumulation of complex oligosaccharides and CAZymes activity under acid conditions constitute the Thatcher+Lr9 defence responses to Puccinia triticina
Puccinia triticina (Pt) is an important pathogen of wheat. While breeding programmes develop resistant wheat cultivars to mitigate the effects of such rust-causing pathogens, the emergence of new rust races with ...

Map** and validation of all-stage resistance to stem rust in four South African winter wheat cultivars
Several South African winter wheat cultivars express all-stage resistance to local races of Puccinia graminis f. sp. tritici (Pgt). To study the inheritance of resistance, cultivars Komati, Koonap, Limpopo and SS...

Characterisation of stem rust resistance in the South African winter wheat cultivar PAN 3161
Stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), poses a threat to wheat production in South Africa (SA). Winter wheat cultivar PAN 3161 displays a high level of resistance to stem rust in the field, ...

Open AccessLong-read genome sequencing of bread wheat facilitates disease resistance gene cloning
The cloning of agronomically important genes from large, complex crop genomes remains challenging. Here we generate a 14.7 gigabase chromosome-scale assembly of the South African bread wheat (Triticum aestivum) c...

Open AccessA recombined Sr26 and Sr61 disease resistance gene stack in wheat encodes unrelated NLR genes
The re-emergence of stem rust on wheat in Europe and Africa is reinforcing the ongoing need for durable resistance gene deployment. Here, we isolate from wheat, Sr26 and Sr61, with both genes independently introd...

Chromosomal composition analysis and molecular marker development for the novel Ug99-resistant wheat–Thinopyrum ponticum translocation line WTT34
A novel Ug99-resistant wheat–Thinopyrum ponticum translocation line was produced, its chromosomal composition was analyzed and specific markers were developed.
