Flowering time measurements in transgenic (TG) and control Arabidopsis plants under long day conditions in response to application of the steroid Dexamethasone (DEX). a-c) Plants were treated with DEX (+DEX) or control solutions (-DEX) from the time of imbibition. n = 10-12. a) Total number of leaves (rosette + cauline) at flowering. The data is presented as mean +/-SD. b) Percentage of plants showing visible floral buds and c) number of leaves developed during the life cycle. For b) and c), the data from the four TG lines is presented as mean +/- SD. d) TG2 plants were treated with DEX or control solutions every 4 days from the days shown and total numbers of leaves at the time of flowering were counted. The data is presented as mean+/-t.se; p = 0.05, n = 4-9. The flowering time of wild type Col plants is shown for comparison.
