Stripe rust (Puccinia striiformis f. sp. tritici (Pst)) is one of the most devastating fungal diseases of durum wheat (Triticum turgidum L. var. durum Desf.). Races of Pst with new virulence combinations are emerging more regularly on wheat-growing continents, which challenges wheat breeding for resistance. This study aimed to identify and characterize resistance to Pst races based on a genome-wide association study. GWAS is an approach to analyze the associations between a genome-wide set of single-nucleotide polymorphisms (SNPs) and target phenotypic traits. A total of 139 durum wheat accessions from Iran were evaluated at the seedling stage against isolates Pstv-37 and Pstv-40 of Pst and then genotyped using a 15K SNP chip. In total, 230 significant associations were identified across 14 chromosomes, of which 30 were associated with resistance to both isolates. Furthermore, 17 durum wheat landraces showed an immune response against both Pst isolates. The SNP markers and resistant accessions identified in this study may be useful in programs breeding durum wheat for stripe rust resistance.
... Indeed, wild relatives of wheat, especially the genera Aegilops and Triticum, are precious genetic resources that contain many genes associated with resistance to different abiotic stresses and have interesting breeding potential. Hence, due to their high level of genetic diversity, these species play a key role in wheat breeding programs [2,[5][6][7][8][9][10]. ...
... Among the wild relatives of wheat, Ae. cylindrica and Ae. tauschii have good potential for use in breeding programs, and various breeding aspects of these species have been highlighted in numerous studies [3][4][5][6]9,10,41]. In this way, Pour-Aboughadareh et al. [6] reported that Ae. tauschii, due to its physiological mechanisms, could be used as an ideal genetic source for discovery of novel genes to improve drought tolerance in bread wheat. ...

Knowledge of the natural patterns of genetic variation and their evolutionary basis is required for sustainable management and conservation of wheat germplasm. In the current study, the genetic diversity and population structure of 100 individuals from four Triticum and Aegilops species (including T. aestivum, Ae. tauschii, Ae. cylindrica, and Ae. crassa) were investigated using two gene-based markers (start codon targeted (SCoT) polymorphism and CAAT-box de-rived polymorphism (CBDP)) and simple-sequence repeats (SSRs). The SCoT, CBDP, and SSR markers yielded 76, 116, and 48 polymorphism fragments, respectively. The CBDP marker had greater efficiency than the SCoT and SSR markers due to its higher polymorphism content in-formation (PIC), resolving power (Rp), and marker index (MI). Based on an analysis of molecu-lar variance (AMOVA) performed using all marker systems and combined data, there was a higher distribution of genetic variation within species than among them. Ae. cylindrica and Ae. tauschii had the highest values for all genetic variation parameters. A cluster analysis using each marker system and combined data showed that the SSR marker had greater efficiency in group-ing of tested accessions, such that the results of principal coordinate analysis (PCoA) and popu-lation structure confirmed the obtained clustering patterns. Hence, combining the SCoT and CBDP markers with polymorphic SSR markers may be useful in genetic fingerprinting and fine mapping and for association analysis in wheat and its germplasm for various agronomic traits or tolerance mechanisms to environmental stresses.

Abstract: Stripe rust (Puccinia striiformis f. sp. tritici (Pst)) is the most devastating fungal disease of durum wheat (Triticum turgidum L. var durum Desf.). Unfortunately, stripe rust races with single and combination gene virulences are emerging more regularly on wheat-growing continents, which challenges wheat breeding for resistance. This study aimed to identify and characterize the resistance to Pst races based on genome-wide association analysis. GWAS is an approach to analyze the associations between a genome-wide set of single-nucleotide polymorphisms (SNPs) and desired phenotypic traits. The quantitative evaluation is based on linkage disequilibrium (LD) through genotyping and phenotyping of diverse individuals. A total of 139 Iranian durum wheat accessions were evaluated at the seedling stage against Pstv-37 and Pstv-40 isolates. A 15K SNP chip was used to identify regions of chromosomes associated with resistance to the two isolates of Pst. In all, we identified 230 significant associations on 14 chromosomes, of which 30 markers were associated with both isolates. These markers can play an important role in marker-assisted selection in breeding programs aimed to improve stripe rust resistance in durum wheat cultivars. Furthermore, 17 durum wheat landraces showed an immune response against both stripe rust isolates, which can be used as a valuable source of resistance genes for future breeding programs. Thus, the present study could contribute to the improvement of durum wheat to mitigate yield losses due to stripe rust.
... As reported in numerous studies, each wild relative of wheat has at least one ideal feature, such as resistance to various biotic and abiotic stresses [4][5][6][7][8][9] . Recently, Pour-Aboughadareh et al. [10] reviewed the potential of different wild wheat species in terms of various biotic and abiotic stresses and indicated that these gene pools how to improve the genetic basis of the bred genotypes. Among the abiotic stresses, drought is the most relevant stress affecting plant growth and production in large parts of the world [1] . ...

Wild relatives of common wheat are an extraordinary source of tolerance to various environmental stresses. The dataset herein presents the effect of water-deficit stress on a core collection of landraces and wild relatives of wheat (including 180 samples belonging to four Triticum and eight Aegilops species [T. boeoticum Bioss., T. urartu Gandilyan., T. durum Def., T. aestivum L., Ae. speltoides Tausch., Ae. tauschii Coss., Ae. caudata L., Ae. umbellulata Zhuk., Ae. neglecta L., Ae. cylindrica Host., Ae. crassa Boiss., and Ae. triuncialis]) in terms of several physiological traits, root and shoot biomasses, and features of root system architecture (RSA). All genetic materials were subjected to water-stress treatment using a pot experiment under greenhouse conditions. To screen the most tolerant accessions, three selection indices, such as Smith and Hazel (SH), factor analysis and ideotype‐design (FAI), and the multi-trait genotype-ideotype distance index (MGIDI) were computed. The obtained data can highlight the role of some features of RSA in increasing water-deficit tolerance in some wild relatives of wheat. Moreover, the use of selection indices in the early stage of growth can be highlighted for future research.

Climate change has been regarded as an indication of biodiversity loss over the past three decades, and it has posed a threat to agriculture around the world. Under this situation, over-exploitation and selection for specific features have resulted in a reduction in genetic diversity, particularly in cultivated cereals. In the primary and secondary gene pools of wheat, no new insights or gene possibilities have been left, as expected. In this approach, plant breeders may be able to generate wheat climate-resilient cultivars by utilizing the diversity of essential genes found in wheat grasses from the tertiary gene pool. The major indicator for sourcing is the adaptation of grasses. Grasses acclimatization is the primary indication for sources of novel abiotic tolerance genes which help them to withstand tropical to temperate environments. Wild grasses hold a significant position in ploidy level and also can maintain flexibility which gives the insight to widen the genomic architecture of cultivated wheat cultivars. In the present article, the information on domestication of wheat, gene pool, and involvement of wheat wild relatives has been summarised. Additionally, the paper highlights the negative effect of wild introgression during successful alien trait transfer.

The present work focused on the identification of durum wheat QTL hotspots from a collection of genome-wide association studies, for quality traits, such as grain protein content and composition, yellow color, fiber, grain microelement content (iron, magnesium, potassium, selenium, sulfur, calcium, cadmium), kernel vitreousness, semolina, and dough quality test. For the first time a total of 10 GWAS studies, comprising 395 marker-trait associations (MTA) on 57 quality traits, with more than 1,500 genotypes from 9 association panels, were used to investigate consensus QTL hotspots representative of a wide durum wheat genetic variation. MTA were found distributed on all the A and B genomes chromosomes with minimum number of MTA observed on chromosome 5B (15) and a maximum of 45 on chromosome 7A, with an average of 28 MTA per chromosome. The MTA were equally distributed on A (48%) and B (52%) genomes and allowed the identification of 94 QTL hotspots. Synteny maps for QTL were also performed in Zea mays, Brachypodium, and Oryza sativa, and candidate gene identification allowed the association of genes involved in biological processes playing a major role in the control of quality traits.

In the present study, we estimated genetic diversity and population structure in 186 accessions of Triticum and Aegilops species using 24 simple sequence repeat markers (SSR). Furthermore, an association analysis was performed for antioxidant activities, including guaiacol peroxidase (GPX), ascorbate peroxidase (APX), peroxidase (POX), catalase (CAT), and dry matter (DM) under two control and drought stress conditions. Our findings showed that drought treatment significantly decreased DM, whereas activities of all antioxidant enzymes were increased compared to the control conditions. The results of correlation analysis indicated that, under drought stress conditions, all biochemical traits had a positive and significant association with each other and with dry matter. In the molecular section, the results of the analysis of molecular variance (AMOVA) indicated that the molecular variation within species is more than within them. The dendrogram obtained by cluster analysis showed that grouping the investigated accessions was in accordance with their genomic constitutions. The results of association analysis revealed 8 and 9 significant marker-trait associations (MTA) under control and drought stress conditions, respectively. Among identified MTAs, two associations were simultaneously found in both growing conditions. Moreover, several SSR markers were associated with multiple traits across both conditions. In conclusion, our results could provide worthwhile information regarding marker-assisted selection for the activity of antioxidant enzymes in future breeding programs.
