“…The results of association analysis for the biochemical profile and other parameters indicated that the MLM model was effective in detecting significant MTAs. This finding is in agreement with previous reports that showed a high efficiency of the MLM method to perfectly present the significant association [ 15 , 16 , 66 , 67 , 68 ]. In this study, a total of eight and nine significant SSR markers associated with DM and activities of antioxidant enzymes in the control and drought stress conditions, respectively ( Table 3 ).…”

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.

“…Barc232, Xbarc124, Xbarc32, Swm271, Xwmc44, Xgwm296, Gpw5029 and Xwmc557 were found to be most proficient. Barc232 was found to be correlated with lipoxygenase (LOX) activity by Zheng et al (2022). It is well established that increased LOX activity is involved in hypersensitive response of wheat cells against rust fungi (Nalam et al 2015).…”

Characterization of wheat (Triticum aestivum) genotypes for multiple fungal resistance using functional markers

et al. 2023

Wheat (Triticum aestivum L.) encounters 15–20% yield loss due to fungal diseases. A study was carried out to analyse the allelic variations in functional genes associated with multiple fungal disease resistance, viz. rusts, smuts and powdery mildew in 58 contrasting wheat genotypes. The experiments were conducted at Chaudhary Charan Singh Haryana Agricultural University, Hisar, Haryana during 2020–21. A set of 29 simple sequence repeat (SSR) markers was selected for screening, out of which 24 markers showed amplifications (82.7%) and 23 showed polymorphism (95.83%) with a total of 46 alleles. Alleles per locus varied from 1 to 3 with a mean of 1.96 alleles per locus. At a similarity coefficient of 0.66, dendrogram grouped all the genotypes into 2 major clusters. Two and three dimensional plots also confirmed the distribution. Results showed that genotypes PBW 725 and WH 1268 were found to be most diverse at a similarity coefficient of 77%. SSR polymorphism rates were analysed using polymorphism information content, expected heterozygosity, marker index, discriminating power and resolving power values, where first two ranged from 0.03–0.65, and later three ranged from 0.03–1.94, 0.03–0.66 and 0.03–2.00, respectively. Based on these results, 8 proficient markers, viz. Barc232, Swm271, Xbarc124, Xbarc32, Xwmc44, Xgwm296, Gpw5029 and Xwmc557 are suggested for Indian wheat fungal disease resistance profiling. Among these, first two markers (Barc232 and Swm271) were detected in most (57) of the genotypes which are associated with ut6 and Lr75 genes, providing resistance to loose smut and leaf rust, respectively. This study can further help in gene pyramiding for producing multiple disease resistant genotypes.

Molecular Markers and Their Applications in Marker-Assisted Selection (MAS) in Bread Wheat (Triticum aestivum L.)

As one of the essential cereal crops, wheat provides 20% of the calories and proteins consumed by humans. Due to population expansion, dietary shift and climate change, it is challenging for wheat breeders to develop new varieties for meeting wheat production requirements. Marker-assisted selection (MAS) has distinct advantages over conventional selection in plant breeding, such as being time-saving, cost-effective and goal-oriented. This review makes attempts to give a description of different molecular markers: sequence tagged site (STS), simple sequence repeat (SSR), genotyping by sequencing (GBS), single nucleotide polymorphism (SNP) arrays, exome capture, Kompetitive Allele Specific PCR (KASP), cleaved amplified polymorphic sequence (CAPS), semi-thermal asymmetric reverse PCR (STARP) and genotyping by target sequencing (GBTS). We also summarize some quantitative trait loci (QTL)/genes as well as their linked markers, which are potentially useful in MAS. This paper provides updated information on some markers linked to critical traits and their potential applications in wheat breeding programs.
