Table I. Cuticular wax extracted from the plant surface compared with total stem wax in vesicle-trafficking mutants of Arabidopsis.
Average wax content (µg cm−2) ± se is shown for trs120-4, rhd3-1, gnl1-1, and ech compared with the Col-0 wild type.
| Parameter | Col-0 | trs120-4 | gnl1-1 | ech | rhd3-1 |
|---|---|---|---|---|---|
| Total wax | 19.8 ± 1.7 | 19.1 ± 1.3 | 12.3 ± 1.1a,b | 6.2 ± 0.6a,c | 8.3 ± 0.8a |
| Surface wax | 18.3 ± 1.2 | 17.7 ± 1.0 | 9.5 ± 0.5a | 3.2 ± 0.6a | 7.4 ± 1.6a |
| Intracellular waxd | 1.5 | 1.4 | 2.8 | 3.0 | 0.9 |
| Percent secreted | 92 | 93 | 77 | 52 | 89 |
a
Statistically significant difference between the mutant and the wild type (Student’s t test, P < 0.01). bStatistically significant difference between surface wax and total wax within a genotype (Student’s t test, P < 0.05). cStatistically significant difference between surface wax and total wax within a genotype (Student’s t test, P < 0.01). dCalculated from average total wax – average surface wax (µg cm−2).
