TE, Transmission efficiency was calculated as the quotient of the number of basta resistant (R) divided by basta susceptible (S) progeny of the indicated cross

χ2 was calculated based on the expectation of a 1:1 segregation of basta resistance to susceptibility in the progeny. GFP-PIGS refers to the T2 line of pPIGS:GFP-PIGS #15–3

^aBasta resistant (Basta^R) and Basta susceptible (Basta^S) progeny. Basta resistance gene is linked with the T-DNA that is inserted into the AtGPI8 (gpi8–2) [25] and LRE (lre-7), AtPIGS (pigs-1), and in an unknown location in the genome of the BastaR/+ line [21]
