Figure 6. Chlorophyll content in over expresser and silenced DcLcyb1 lines of carrot plants.

Chlorophyll amount in leaves of over expresser and silenced lines was determined by spectrophotometry and HPLC. The chlorophyll amount in wild-type was set at 100%. For this analysis, leaves of three month-old plants were used. Columns and bars represent the means and SE (n = 3). Asterisks indicate significant differences between transgenic lines and the wild type plant. Non-paired one and two tailed t-tests (p<0.05) were performed for all the transgenic lines and the wild type plant.
