abstract：:Virions of southern bean mosaic virus (SBMV) show two distinct sensitivity patterns upon heating. Infectivity loss and capsid denaturation occur concurrently if virions are exposed at 50-55 degrees in 0.1 M sodium phosphate buffer, pH 7.5, or 0.1 M glycine-phosphate buffer, pH 9.0. Contrastingly, virions are inactivat...
