Susceptibility of Arabidopsis Ecotypes to TEV, PVY, and TVMV Strains.

Plants were inoculated with three strains of TEV, two strains of PVY, and one strain of TVMV. Normalized samples from inoculated rosette (I) or systemic inflorescence (S) tissue at 15 DPI were subjected to immunoblot analysis by using anti–capsid protein serum specific for the respective viruses. The four ecotypes tested–Col-3, Ws-2, C24, and Ler (La-er)–each contain functional, dominant RTM2 alleles. Two ecotypes contain dominant, functional RTM1 alleles (Col-3 and Ws-2), and two ecotypes contain recessive rtm1 alleles (C24 and Ler).
