Table 1 Transmission of the heterozygous bet11-1 and bet12-1 alleles is impaired in bet11/12 double mutants

From: Arabidopsis Qc-SNARE genes BET11 and BET12 are required for fertility and pollen tube elongation

Cross Segregating T-DNA allele Expected segregation rate (E) Observed segregation rate (O) Transmission efficiency (O/E) × 100 (%)
bet11 HM/bet12 HZ (female) × WT (male) bet12 50 21 42
WT (female) × bet11 HM/bet12 HZ bet12 50 11 22
bet12 HM/bet11 HZ (female) × WT (male) bet11 50 12 24

  1. Results show the segregation rates of the bet11-1 and bet12-1 alleles after reciprocal crosses involving the wild type (WT) and bet11/bet12 double mutants in either the homozygous/heterozygous (HM/HZ) or the HZ/HM condition. From left to right, the table indicates the expected Mendelian segregation rate (E), the actual observed segregation rate (O) and the transmission efficiency (O/E × 100). For the bet11 HM/bet12 HZ line, maternal transmission efficiency of the bet12-1 heterozygous (HZ) allele was low (42 %). Even lower values in the transmission efficiency of bet12-1 allele were observed when the T-DNA allele was transmitted paternally through pollen (22 %). For the bet11 HZ/bet12 HM line, maternal and paternal transmission efficiencies of the heterozygous bet11-1 allele were low (24 and 14 %). Data was collected from 100 segregating seedlings per cross
