Improving wheat grain composition for human health by constructing a QTL atlas for essential minerals

P. P. Sigalas, P. R. Shewry, et al.

This groundbreaking study identifies 23 quantitative trait loci (QTLs) for essential minerals in wheat grain, utilizing three biparental populations. The discovery of the ATPase transporter gene responsible for the strongest QTL on chromosome 5A for calcium is pivotal for enhancing grain nutritional quality. This research was conducted by a team of experts including Petros P. Sigalas and Peter R. Shewry.

Abstract

This study identifies quantitative trait loci (QTLs) for essential minerals in wheat grain by analyzing three biparental populations. Twenty-three QTLs, mapped in at least two sample sets with LOD scores above five in at least one set, were identified across 14 chromosomes. The gene responsible for the strongest QTL (chromosome 5A for Ca) was identified as an ATPase transporter gene (*TraesCS5A02G543300*) using mutagenesis. These findings facilitate the improvement of grain nutritional quality.
