Abstract
Two strains of Kalanchoë Latent Virus, KLV PV-0290 and KLV 1452, which both infect Kalanchoë blossfeldiana systemically, differ in their ability to infect Chenopodium quinoa. KLV PV-0290 is restricted to locally infected leaves, whereas KLV 1452 spreads to uninoculated leaves.
In this study, 11 spontaneous mutants of KLV PV-0290 able to spread to uninoculated leaves were isolated and the amino acid sequences of their coat protein (CP) were compared.
Amino acids in positions 13, 18, and 19 in the N-terminal of the CP were shown to be involved in the modulation of the ability to move long-distance of these mutants.
