Permanent Spreading of 1RS.1AL and 1RS.1BL Translocations in Modern Wheat Breeding. PLANTS (BASEL, SWITZERLAND) 2023; 12:1205. [PMID: 36986893 PMCID: PMC10051305 DOI: 10.3390/plants12061205] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Revised: 03/03/2023] [Accepted: 03/04/2023] [Indexed: 06/18/2023]
Abstract
Wheat-rye translocations 1RS.1BL and 1RS.1AL are used in bread wheat breeding worldwide because a short arm of rye chromosome 1 (1RS) when introgressed into the wheat genome confers resistance to diseases, pests and better performance under drought-stress conditions. However, in durum wheat genotypes, these translocations occur only in experimental lines, although their advantages could enhance the potential of this crop. P.P. Lukyanenko National Grain Centre (NGC) has successfully developed commercially competitive cultivars of bread and durum wheat demanded by many agricultural producers in the South of Russia for decades. Here, 94 accessions of bread and 343 accessions of durum wheat, representing lines and cultivars from collection, competitive variety trials and breeding nursery developed at NGC were screened for 1RS using PCR markers and genomic in situ hybridization. The 1RS.1BL and 1RS.1AL translocations were detected in 38 and 6 bread wheat accessions, respectively. None of the durum wheat accessions showed translocation, despite the fact that some of them had 1RS.1BL donors in their pedigree. The absence of translocations in the studied durum wheat germplasm can be caused by the negative selection of 1RS carriers at different stages of the breeding process due to low quality and difficulties in transferring rye chromatin through wheat gametes.

1RS arm of Secale cereanum 'Kriszta' confers resistance to stripe rust, improved yield components and high arabinoxylan content in wheat. Sci Rep 2020; 10:1792. [PMID: 32019962 PMCID: PMC7000720 DOI: 10.1038/s41598-020-58419-3] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Accepted: 12/03/2019] [Indexed: 11/08/2022] Open
Abstract
Wheat-rye T1BL.1RS translocation is widespread worldwide as the genes on 1RS arm have positive effect on stress resistance, grain yield and adaptation ability of wheat. Nowadays, the T1BL.1RS wheat cultivars have become susceptible to rust diseases because of the monophyletic ('Petkus') origin of 1RS. Here we report and discuss the production and detailed investigation of a new T1BL.1RS translocation line carrying 1RS with widened genetic base originating from Secale cereanum. Line '179' exhibited improved spike morphology traits, resistance against stripe rust and leaf rust, as well as higher tillering capacity, fertility and dietary fiber (arabynoxylan) content than the parental wheat genotype. Comparative analyses based on molecular cytogenetic methods and molecular (SSR and DArTseq) makers indicate that the 1RS arm of line '179' is a recombinant of S. cereale and S. strictum homologues, and approximately 16% of its loci were different from that of 'Petkus' origin. 162 (69.5%) 1RS-specific markers were associated with genes, including 10 markers with putative disease resistance functions and LRR domains found on the subtelomeric or pericentromeric regions of 1RS. Line '179' will facilitate the map-based cloning of the resistance genes, and it can contribute to healthy eating and a more cost-efficient wheat production.

Properties of Gluten Intolerance: Gluten Structure, Evolution, Pathogenicity and Detoxification Capabilities. Nutrients 2016; 8:nu8100644.

Abstract
Theterm gluten intolerance may refer to three types of human disorders: autoimmune celiac disease (CD), allergy to wheat and non-celiac gluten sensitivity (NCGS). Gluten is a mixture of prolamin proteins present mostly in wheat, but also in barley, rye and oat. Gluten can be subdivided into three major groups: S-rich, S-poor and high molecular weight proteins. Prolamins within the groups possess similar structures and properties. All gluten proteins are evolutionarily connected and share the same ancestral origin. Gluten proteins are highly resistant to hydrolysis mediated by proteases of the human gastrointestinal tract. It results in emergence of pathogenic peptides, which cause CD and allergy in genetically predisposed people. There is a hierarchy of peptide toxicity and peptide recognition by T cells. Nowadays, there are several ways to detoxify gluten peptides: the most common is gluten-free diet (GFD), which has proved its effectiveness; prevention programs, enzymatic therapy, correction of gluten pathogenicity pathways and genetically modified grains with reduced immunotoxicity. A deep understanding of gluten intolerance underlying mechanisms and detailed knowledge of gluten properties may lead to the emergence of novel effective approaches for treatment of gluten-related disorders.

Abstract
Wheat-Secale cereanum addition lines with yellow rust resistance (6R) and increased arabinoxylan content (1R, 4R, 6R) have been selected and identified in order to increase biodiversity of wheat. Perennial rye (Secale cereanum, 2n = 2x = 14, RR) cultivar Kriszta has a large gene pool that can be exploited in wheat breeding. It has high protein and dietary fibre content, carries several resistance genes, tolerant to frost and drought, and adapts well to disadvantageous soil and weather conditions. In order to incorporate agronomically useful features from this perennial rye into cultivated wheat, backcross progenies derived from a cross between the wheat line Mv9kr1 and perennial rye 'Kriszta' have been produced, and addition lines disomic for 1R, 4R and 6R chromosomes have been selected using GISH, FISH and SSR markers. Quality measurements showed that addition of 'Kriszta' chromosomes 4R and 6R to the wheat genome had increased the total protein content. The 4R addition line contained slightly, while 1R and 6R additions significantly higher amount of arabinoxylan than the parental wheat line. Besides this, the 6R addition line appeared to be resistant to yellow rust in highly infected nurseries, consequently it may carry a new effective gene different from that harboured in the 1RS.1BL translocation for resistance to this disease.
