Abstract

The research aimed at evaluating and exploring the major genomic regions responsible for pre-harvest sprouting resistance in wheat. Genomic and transcriptomic profiling of near isogenic lines targeting two major quantitative trait loci on chromosome 3A and 4B revealed candidate genes underlying the loci, with most of the genes involved in hormone signalling pathway and energy metabolism. Single nucleotide polymorphism and insertion deletion polymorphism markers were also identified within the targeted genomic regions. The developed near isogenic lines and the identified candidate genes and markers are valuable resources for further fine mapping of the loci to pinpoint the underlying genes.
