Application of pangenomics for wheat molecular breeding.

Abstract This chapter discusses the application of pangenomics for molecular breeding of wheat. Pangenomes can be used by both researchers and breeders alike to develop elite wheat cultivars through the discovery and integration of genetic variations associated with agronomically beneficial traits. By providing a reference that accommodates for variation in individuals, variants whose presence and/or absence control abiotic stress resistance and yield can be identified. This tool has only become more informative as more wheat varieties are sequenced, new sequencing approaches such as long-read sequencing and genome mapping are utilized, and tools for pangenomic analysis are developed. With pangenomics, variable genes from wild wheat relatives and related species can be used to optimize wheat molecular breeding and develop improved varieties tailored for the changing global environment.

Negative Effect

Global climate change in recent years has resulted in extreme heat and drought events that significantly influence crop production and endanger food security. Such abiotic stress during the growing season has a negative effect on yield as well as on the functional properties of wheat grain protein content and composition. This reduces the value of grain, as these factors significantly reduce end-use quality. In this study, four Hungarian bread wheat cultivars (Triticum aestivum ssp. aestivum) with different drought and heat tolerance were examined. Changes in the size- and hydrophobicity-based distribution of the total proteins of the samples have been monitored by SE- and RP-HPLC, respectively, together with parallel investigations of changes in the amounts of the R5 and G12 antibodies related to celiac disease immunoreactive peptides. Significant difference in yield, protein content and composition have been observed in each cultivar, altering the amounts of CD-related gliadin, as well as the protein parameters directly related to techno-functional properties (Glu/Gli ratio, UPP%). The extent of changes largely depended on the timing of the abiotic stress. The severity of the negative effect depended on the growth stage in which abiotic stress occurred.
