Table II. Frequency of wild-type, heterozygous, and homozygous alleles found for the Arabidopsis T-DNA allele pgd2-1 in the qrt1-2 background.

CS8846, point mutation in QRT1 (Preuss et al., 1994; Copenhaver et al., 1998) encoding a pectin methylesterase (Francis et al., 2006).

SALK_036751 × CS8846	(Back)cross	No.	PGD2 PGD2	PGD2 pgd2-1	pgd2-1 pgd2-1

Mean of heterozygous plants after selfing (both pgd2 alleles and pgd2-1 in qrt2-1; Table I) = 48.6%. ^bMean of heterozygous plants after female backcrosses (including qrt2-1; Table I) = 46.7%.
