A comparative study of the alkaline disassembly of two strains of tobacco mosaic virus.
Exposure of tobacco (Tb) and tomato (Tm) isolates of tobacco mosaic virus (TMV) to dilute alkaline solutions (pH > 8.0) at 0 degrees results in disassembly of the virus particles. Over the range of pH and NaCl concentration studied, Tm-TMV was more sensitive to alkaline conditions than was Tb-TMV. Kinetic analysis demonstrates that both isolates disassemble in a stepwise manner and that each produces six major intermediate-size particles.
