The WGR approach has been used in soybean to identify the Quantitative trait loci (QTL) determining colonization of arbuscular mycorrhizal fungi (AFM). The microbial community like AFM can associate with 80% of the terrestrial plants and help host plants to uptake more nutrients, provide tolerance against stresses. The colonization and extent of benefits provided by AFM depend on the host genotypes. QTL is responsible for mycorrhizal responsiveness in different plants. Pawlowski and coworkers investigated the genetic components that are involved in the AFM association. The aim of the study was the genome‐wide association analysis to identify the difference in AFM colonization in soybean genotypes and identification of genomic regions that are responsible for the colonization of AFM. They had used a genetically diverse set of 350 soybean genotypes inoculated with AFM (i.e. Rhizophagus intraradices). By using whole‐genome resequencing‐derived SNP dataset, they identified six QTL involved in the colonization of the AFM. The candidate genes identified in these QTL regions contain the homologs of the nodulin protein family and other genes responsible for symbiosis (Pawlowski et al. 2020).
