Phenotypes of Primary 35S-Pac1 Transformants while under Basta Herbicide Selection
| Allele (Background)a | Number of Seedlings with Trichomes (Total Scored)bc | Number of Plants with Trichomes Yielding Brown Seed and Mature Plant Anthocyanins (Total Scored) |
|---|---|---|
| ttg1-1 (Columbia) | 26 (39) | 6 (6) |
| ttg1-1 (Landsberg erecta) | 13 (15) | 3 (3) |
| ttg1-13 | 12 (16) | 1 (1) |
a
The ttg1-13 allele was partially introgressed from the RLD ecotype into Columbia.
b
Number of trichomes per first true leaf ranged from 4 to 38 trichomes with an average of 17.7 trichomes (sd of 7.3, n = 30 plants, all alleles pooled). No trichomes were seen in several hundred nontransformed ttg1 mutants.
c
All plants lacking trichomes as seedlings lacked anthocyanins as mature plants. The four such plants that were followed to silique shatter yielded yellow seed, consistent with no proanthocyanidin synthesis.
