Fig. 1. GL3 and EGL3 RNA accumulates in all major Arabidopsis organs. Reverse transcriptase (RT)-PCR analysis using GL3-, EGL3-or UBQ10-specific gene primers. Total RNA was isolated from the following tissues of wild-type (Columbia) plants: roots, hypocotyl and cotyledons, rosette leaves, cauline leaves, stems and flowers. 500 ng template RNA was used for each RT-PCR reaction.
