Photosynthetic pigment levels in wild-type and tdy2 leaves
Data represent means from six samples ± se.
| Leaf Tissue | Chlorophyll a | Percentage of Wild Type | Chlorophyll b | Percentage of Wild Type | Chlorophyll a/b | Total Carotenoids | Percentage of Wild Type |
|---|---|---|---|---|---|---|---|
| μg/g fresh weight | μg/g fresh weight | μg/g fresh weight | |||||
| Wild type | 1,278.6 ± 111.8 | 100 | 369.5 ± 21.5 | 100 | 3.46 | 320.9 ± 4.2 | 100 |
| tdy2 green | 1,242.2 ± 43.5 | 97.2 | 363.5 ± 19.5 | 98.4 | 3.42 | 308.9 ± 10.1 | 96.2 |
| tdy2 chlorotic | 829.9a ± 67.8 | 65.0 | 192.2a ± 17.8 | 52.0 | 4.32 | 220.5a ± 7.0 | 68.7 |
a
Value is significantly different from wild type at P ≤ 0.01 using the Student's t test.
