Abstract
Leaf rust (LR), caused by Puccinia triticina (Pt), is one of the most important fungal diseases of wheat worldwide. The wheat accession CH1539 showed a high level of resistance to leaf rust. A mapping population of 184 recombinant inbred lines (RILs) was developed from a cross between the resistant accession CH1539 and the susceptible cultivar SY95-71. The RILs showed segregating infection responses to Puccinia triticina Eriks. (Pt) race THK at the seedling stage. Genetic analysis showed that leaf rust resistance was controlled by a monogenic gene, and the potential locus was temporarily named LrCH1539. Bulked segregant analysis (BSA) using a 35 K DArTseq array located LrCH1539 on the short arm of chromosome 2B. Subsequently, a genetic linkage map of LrCH1539 was constructed using the developed 2BS chromosome-specific markers, and its flanking markers were sxau-2BS136 and sxau-2BS81. An F2 subpopulation with 3619 lines was constructed by crossing the resistant and susceptible lines selected from the RIL population. The inoculation identification results showed that LrCH1539 was recessively inherited and was fine-mapped to a 779.4-kb region between markers sxau-2BS47 and sxau-2BS255 at the end of 2BS. The linkage marker analysis showed that the positions of LrCH1539 and Lr16 were the same, but the identification results of the resistance spectrum indicated that the causal genes of the two might be different. The resistant materials reported in this study and the cosegregation marker can be used for marker-assisted selection breeding of leaf rust-resistant wheat cultivars.

Identification of Leaf Rust Resistance Genes in Selected Wheat Cultivars and Development of Multiplex PCR. Open Life Sci 2019; 14:327-334. [PMID: 33817166 PMCID: PMC7874803 DOI: 10.1515/biol-2019-0036] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Accepted: 04/24/2019] [Indexed: 11/18/2022] Open
Abstract
Ten leading wheat cultivars originating from the Plant Breeding and Acclimatization Institute (IHAR) - National Research Institute (Poland) and the Department of Gene Bank (Czech Republic) were used to establish a field experiment in 2017 and 2018 at the Dłoń Experimental Farm. The analyzed wheat genotypes were characterized by diversified field resistance to leaf rust. Jubilatka, Thatcher and Sparta were the most resistant cultivars in field conditions in both 2017 and 2018. The aim of the work was to identify the Lr11, L13, Lr16 and Lr26 genes encoding resistance to leaf rust using molecular SSR markers (wmc24, wmc261, Xgwm630, Xwmc764 and P6M12) and to develop multiplex PCR conditions to accelerate identification of these genes. Markers of three leaf rust resistance genes have been identified simultaneously in these cultivars. Jubilatka, Thatcher and Sparta cultivars may serve as a good source of the analyzed leaf rust resistance genes. In addition, multiplex PCR conditions have been developed for the simultaneous identification of the Lr11 and Lr16 and Lr11 and Lr26 gene pairs.

Highly predictive SNP markers for efficient selection of the wheat leaf rust resistance gene Lr16. BMC PLANT BIOLOGY 2017; 17:45. [PMID: 28202046 PMCID: PMC5311853 DOI: 10.1186/s12870-017-0993-7] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/27/2016] [Accepted: 01/31/2017] [Indexed: 05/02/2023]
Abstract
BACKGROUND Lr16 is a widely deployed leaf rust resistance gene in wheat (Triticum aestivum L.) that is highly effective against the North American Puccinia triticina population when pyramided with the gene Lr34. Lr16 is a seedling leaf rust resistance gene conditioning an incompatible interaction with a distinct necrotic ring surrounding the uredinium. Lr16 was previously mapped to the telomeric region of the short arm of wheat chromosome 2B. The goals of this study were to develop numerous single nucleotide polymorphism (SNP) markers for the Lr16 region and identify diagnostic gene-specific SNP marker assays for marker-assisted selection (MAS). RESULTS Forty-three SNP markers were developed and mapped on chromosome 2BS tightly linked with the resistance gene Lr16 across four mapping populations representing a total of 1528 gametes. Kompetitive Allele Specific PCR (KASP) assays were designed for all identified SNPs. Resistance gene analogs (RGAs) linked with the Lr16 locus were identified and RGA-based SNP markers were developed. The diagnostic potential of the SNPs co-segregating with Lr16 was evaluated in a diverse set of 133 cultivars and breeding lines. Six SNP markers were consistent with the Lr16 phenotype and are accurately predictive of Lr16 for all wheat lines/cultivars in the panel. CONCLUSIONS Lr16 was mapped relative to SNP markers in four populations. Six SNP markers exhibited high quality clustering in the KASP assay and are suitable for MAS of Lr16 in wheat breeding programs.
