Abstract excerpt
The 68th amino acid residue (cysteine, C68) in tobacco mosaic virus (TMV) movement protein (MP) and the corresponding position in some tobamoviruses are required to trigger Tm-22-mediated resistance. In contrast, the 67th amino acid residue (histidine, H67) in tomato brown rugose fruit virus (ToBRFV) MP enables evasion, although its key property remains unclear. To assess the key property of this site, a...
