Genetic variability of Puccinia triticina Eriks. in Brazil [PDF]

Summa Phytopathologica, 2012
Studies on the genetic variability of Puccinia triticina in inoculum collected in Brazil started in 1941 with Vallega (20). The pioneering work in Brazil dates from 1949 (16) at "Instituto Agronômico do Sul", Ministry of Agriculture (MA), in Pelotas, Rio Grande do Sul State (RS), and continued after 1975 at Embrapa Wheat in Passo Fundo, RS.

Characterization of Lr46, a gene conferring partial resistance to wheat leaf rust [PDF]

, 2001
Components of resistance conferred by the Lr46 gene, reported as causing "slow rusting" resistance to leaf rust in wheat, were studied and compared with the effects of Lr34 and genes for quantitative resistance in cv. Akabozu. Lr34 is a gene that confers

Effective leaf rust resistance genes of wheat in Novosibirsk Province in connection with the variability of the Puccinia triticina population

Труды по прикладной ботанике, генетике и селекции, 2023
Background. Information on the races of Puccinia triticina Erikss. in Novosibirsk Province is needed to identify sources of effective genes for leaf rust resistance. The goal hereof was monitoring genetic variability of the P. triticina population in the

Variation in aggressiveness is detected among Puccinia triticina isolates of the same pathotype and clonal lineage in the adult plant stage [PDF]

, 2012
Puccinia triticina reproduces asexually in France and thus individual genotype is the unit of selection. A strong link has been observed between genotype identities (as assessed by microsatellite markers) and pathotypes (pools of individuals with the ...

De Novo Assembled Wheat Transcriptomes Delineate Differentially Expressed Host Genes in Response to Leaf Rust Infection. [PDF]

PLoS ONE, 2016
Pathogens like Puccinia triticina, the causal organism for leaf rust, extensively damages wheat production. The interaction at molecular level between wheat and the pathogen is complex and less explored.

Comparative genomics of Australian isolates of the wheat stem rust pathogen Puccinia graminis f. sp. tritici reveals extensive polymorphism in candidate effector genes [PDF]

, 2015
The wheat stem rust fungus Puccinia graminis f. sp. tritici (Pgt) is one of the most destructive pathogens of wheat. In this study, a draft genome was built for a founder Australian Pgt isolate of pathotype (pt.) 21-0 (collected in 1954) by next ...

Molecular Diversity in Puccinia triticina Isolates from Ethiopia and Germany [PDF]

Journal of Phytopathology, 2006
AbstractA total of 43 isolates of the wheat leaf rust fungus, Puccinia triticina Eriks, collected from Ethiopia and Germany were analysed for their genetic diversity using the amplified fragment length polymorphism (AFLP) technique. Out of 18 EcoRI/MseI primer combinations screened, 15 produced 219 highly polymorphic fragments.
