Comprehensive analysis of soybean cultivars' response to SMV infection: genotypic association, molecular characterization, and defense gene expressions.

Background: Soybean mosaic virus (SMV) is a devastating disease that threatens soybean plants worldwide. The different soybean genotypes displayed different responses to SMV strains. This study aimed to investigate the response of different selected soybean cultivars to SMV infection in Egypt based on their specific genetic makeup.
