Córdoba team verifies wheat GLU-B1 diversity
The researchers assembled wheat samples from 33 countries into a reference collection for research and breeding.
Today in brief
A University of Córdoba team concluded that wheat’s GLU-B1 gene has less than half the diversity implied by a catalogue of 98 variants.1 The researchers built a collection of verified variants from wheat samples representing 33 countries.1
Researchers find duplicate entries in wheat gene catalogue
Many listed GLU-B1 variants were duplicates or triplicates, Francisco Andrade said.1 The catalogue listed 98 variants, but researchers had not directly compared every entry.1 The team concluded that actual variability was less than half the total implied by the catalogue.1
The researchers traced wheat samples from 33 countries through published studies and germplasm banks, then identified variants and removed duplicates.1 The reference collection is intended to support research into wheat quality and help breeders select useful genetic variation.1
The team previously studied the related gene GLU-A1 and identified a rare variant linked to better baking performance and higher grain protein content.1 Researchers later created a molecular marker to help breeders identify and select that variant.1
