Table II. Genotyping and segregation analysis of reciprocal outcrosses in sec3a-1 mutant and complementation lines.

Shown is a summary of Sd-resistant and -sensitive progeny in reciprocal outcrosses of sec3a-1+/−, sec3a-1+/−/LAT52:SEC3a, and sec3a-1+/−/LAT52:GFP-SEC3a to the Columbia-0 (Col-0) background. *, The difference from expected could be explained by the variable expression levels of the complementation constructs in individual pollen. The χ2 test was applied for statistical analysis: P ≤ 0.005 indicates that observed data differ significantly from the expected data; NS, not significantly different.
