Other claims from this paper (13)
- Method / resource Whole-genome sequencing of 291 wild emmer wheat accessions yielded 3.4 million high-quality SNPs.
- Observation Phylogenetic, principal component and population structure analyses revealed three distinct wild emmer subgroups: Northern Population, Southern Levant and a differentiated judaicum subgroup.
- Observation Diversity and pairwise FST analyses showed varying divergence among the wild emmer subpopulations.
- Observation SL accessions had the highest frequency of resistance to all rust pathogens.
- Observation NP accessions lacked stem rust resistance.
- Observation NP accessions retained resistance to some leaf and stripe rust races.
- Observation GWAS identified 27 significant loci associated with stem rust resistance in wild emmer wheat.
- Observation GWAS identified 26 significant loci associated with leaf rust resistance in wild emmer wheat.
- Observation GWAS identified 41 significant loci associated with stripe rust resistance in wild emmer wheat.
- Observation A major resistance hotspot on chromosome 1BS (about 50-100 Mb) was associated with multiple races of different rust pathogens.
- Association The most significant loci explained up to 73% of the phenotypic variation.
- Observation Several wild emmer accessions exhibited broad-spectrum rust resistance.
- Recommendation The identified loci and resistant accessions offer opportunities for targeted introgression of novel resistance genes into cultivated wheat.
