Untargeted Metabolomics Reveals a Multi-Faceted Resistance Response to Fusarium Head Blight Mediated by the Thinopyrum elongatum Fhb7E Locus Transferred via Chromosome Engineering into Wheat

Abstract: The Thinopyrum elongatum Fhb7E locus has been proven to confer outstanding resistance to Fusarium Head Blight (FHB) when transferred into wheat, minimizing yield loss and mycotoxin accumulation in grains. Despite their biological relevance and breeding implications, the molecular mechanisms underlying the resistant phenotype associated with Fhb7E have not been fully uncovered. To gain a broader understanding of processes involved in this complex plant–pathogen interaction, we analysed via untargeted metabolomi… Show more

“…To overcome this narrow genetic variation in durum wheat, many studies have been conducted to introgress resistance from wild or cultivated relatives to durum what, e.g. T. dicoccoides , T. dicoccum, T. elongatum and T. carthlicum [ 13 , 18 , 19 , 33 , 69 , 70 , 72 , 73 ]. Introgression of exotic genes into elite germplasm might be accompanied with the transfer of undesired morphological trait, thus mining and stacking minor-effect resistance QTL from adapted durum germplasm will contribute to enrich the gene pool and improve resistance levels without compromising the elite germplasm characteristics.…”
