Table 1.
Results of the self- and outcrosses of plants heterozygous for AtSEC24A (+/–). Number of progeny indicates the number of seedlings that were genotyped from independent siliques developed upon successful crosses (No. of crosses). ++: Wild type; +/–: heterozygote; m/m homozygous for the T-DNA insertion. Results of the Chi-square distribution (χ2) analysis are indicated along with the probability value (P).
