Other claims from this paper (15)
- Observation The 248 MAGIC wheat lines and their founders showed significant genetic variation and adaptive diversity for physiological traits across multiple locations.
- Intervention effect Under timely sown irrigated conditions, wheat genotypes showed higher canopy greenness, chlorophyll stability and photosynthetic efficiency than under late-sown conditions.
- Intervention effect Late-sown irrigated conditions elevated canopy temperature in wheat compared with timely sown conditions.
- Intervention effect Late-sown irrigated conditions reduced SPAD chlorophyll content in wheat compared with timely sown conditions.
- Association NDVI was positively correlated with SPAD and Fv/Fm in wheat.
- Association NDVI was negatively correlated with canopy temperature in wheat.
- Observation Two principal adaptive axes explained 65-82% of total variation in the measured wheat traits.
- Observation GWAS detected 54 significant marker-trait associations in wheat, predominantly on chromosome 5A.
- Association Major loci AX-95210025, AX-94980357 and AX-94448771 influenced NDVI, SPAD chlorophyll content and CT in wheat.
- Association Major loci AX-95210025, AX-94980357 and AX-94448771 influenced Fv/Fm (UP and LW) in wheat.
- Association Favorable alleles reduced canopy temperature in wheat.
- Observation In-silico and gene regulatory network analyses identified heat-responsive candidate genes in wheat, including TraesCS5A02G078000, TraesCS5A02G077900 and TraesCS1A02G098800.
- Observation In-silico and gene regulatory network analyses identified heat-responsive candidate genes in wheat, including TraesCS7A02G143900 and TraesCS7B02G083500.
- Mechanism The candidate genes are proposed to regulate chlorophyll maintenance, PSII repair and canopy cooling under stress.
- Recommendation The study identifies robust targets for marker-assisted selection and genomic improvement of thermotolerant wheat.
