Ancient barley landraces adapted to marginal soils demonstrate exceptional tolerance to manganese limitation.

ABSTRACT: BACKGROUND AND AIMS:Micronutrient deficiency in cereals is a problem of global significance, severely reducing grain yield and quality in marginal soils. Ancient landraces represent, through hundreds of years of local adaptation to adverse soil conditions, a unique reservoir of genes and unexplored traits for enhancing yield and abiotic stress tolerance. Here we explored and compared the genetic variation in a population of Northern European barley landraces and modern elite varieties, and their tolerance to manganese (Mn) limitation. METHODS:A total of 135 barley accessions were genotyped and the genetic diversity was explored using Neighbor-Joining clustering. Based on this analysis, a sub-population of genetically diverse landraces and modern elite control lines were evaluated phenotypi
