The effects of heterologous and homologous coat protein on alkaline disassembly of tobacco and tomato isolates of tobacco mosaic virus.
Tobacco (Tb) and tomato (Tm) isolates of tobacco mosaic virus (TMV) disassemble in dilute alkaline solutions (pH > 8.0). Tm-TMV is more sensitive to alkali than is Tb-TMV. Tb protein is, however, able to partially stabilize both Tm-TMV and Tb-TMV, thus retarding the rate of alkaline disassembly. Tm protein is unable to stabilize Tm-TMV and also increases the rate of alkaline disassembly of Tb-TMV.
