Transmission efficiency of the heterozygous mutant of MGT9 and identification of MGT9+/- progeny via self-pollination under high Mg condition. Parental Genotypes Male WT MGT9+/a MGT9+/- Female MGT9+/WT a MGT9+/- Genotypes of Progeny MGT9+/+ 114 221 148 MGT9+/116 0 150 mgt9-/0 0 0 Total TEf TEm 230 221 298 50.43% NA NA NA 0 NA The transmission efficiencies (TE) were calculated according to the following equation: TE = number of progenies with T-DNA insertion/number of total progeny × 100%. For normal transmission, 50% reciprocal crosses were expected. TEF, female transmission efficiency; TEM, male transmission efficiency; NA, not applicable. a, heterozygous mutant of MGT9 were grown in 10 mM Mg condition.
