Figure 4.

Seedling phenotypes of Arabidopsis transformants containing a wild-type or eto2 ACS5 transgene. The transgene contained in each line is indicated above the seedling pictures, as is the background into which the transgene was transformed; − indicates that the line was not transformed. Seedlings were plated on either MS medium or MS medium supplemented with 5 μM BA as indicated below each picture. The seedlings were grown for 3 days in the dark, and representative seedlings were picked and photographed. Note that transformation with the eto2 version of ACS5 results in a constitutive triple-response phenotype.
