Natural variation of gibberellin responses in Arabidopsis thaliana

To assess natural variation in the ability to respond to changes in gibberellin metabolism, we examined the effect of the ectopic expression of GA20ox1 in 10 Arabidopsis thaliana accessions. RNA-seq was performed on the sixth leaf, which was micro-dissected (size < 0.25 mm2) at the beginning of the transition from cell proliferation to cell expansion.
