Genetic and histological studies on the delayed systemic movement of Tobacco Mosaic Virus in Arabidopsis thaliana

Table 2 Genetic analysis of the delay in systemic movement of TMV-U1 in Col-0

Cross^a	Fast movement	Delayed movement	Total	χ^2c
F1 Uk-4 × Col-0^b	60	0	60	-
F1 Col-0 × Uk-4	50	0	50	-
F2 Uk-4 × Col-0	198	79	277	1.8
F2 Col-0 × Uk-4	82	30	112	0.76

a: The female parent is represented first in the cross. Six week-old F1 and F2 plants were inoculated and the fast or delayed movement phenotype was determined in infected plants by means of Western blot at 12 dpi.
b: The presented data corresponds to one pair of reciprocal crosses.
c: The values of χ² and p were calculated to test the probability that this data collected in the segregated population corresponds to the expected values for segregation of 3:1 for a single recessive locus that is responsible of delay in systemic movement of TMV-U1 in Col-0. In both cases p > 0.05.
