“…Barley has a typical fibrous root system like rice. We previously evaluated RGA variation among Japanese barley accessions using hydrogel polymer medium, and revealed that the RGA are related to the geographic distribution of the accessions (Konishi et al 2021). QTL mapping and GWAS have identified several loci associated with RGA variation in barley (Robinson et al 2016, Sayed et al 2017, Jia et al 2019.…”

The root growth angle (RGA) is an important breeding target that confers high crop adaptability to deleterious environments. In barley, natural variations in RGA among accessions have been observed, but many of the genetic factors that cause of this variation remains unclear. In this study, we explored the orthologs of OsDRO1 (DEEPER ROOTING 1) and OsqSOR1 (quantitative trait locus for SOIL SURFACE ROOTING 1), which play a critical role in RGA regulation in rice, from barley genome and analyzed the polymorphisms of these genes among barley accessions. BLASTP search detected putative orthologs of OsDRO1 and Osq-SOR1 in barley (HvDRO1 and HvqSOR1) with more than 60% amino acid similarity. Sequence analysis identified SNPs causing mis-splicing and nonsynonymous amino acid substitution in HvDRO1 and HvqSOR1, respectively. These SNPs were associated with RGA variation among the 47 barley accessions. Phylogenetic analysis using the 105 barley accessions revealed that the alleles of HvDRO1 and HvqSOR1 are related to the genetic background of the accessions. Furthermore, the mutant allele of HvDRO1 is mainly shared in the Hokuriku/Nagano subpopulation, suggesting that the mutant allele is involved in local adaptation of barley cultivars to the soil environment of the region. Our findings suggest that the polymorphisms of HvDRO1 and HvqSOR1 are possible determinants of RGA variation in barley, at least in Japanese accessions, and provide infor-mation on allelic variants of the genes for markerassisted selection to genetic improvement of RGA of barley.
