Fig. 4. Western blots of whole-cell extracts from 2-week-old transgenic seedlings
of ML1::2xGFP and
ML1::NLS:2xGFP (A), ML1::AP1:GFP and
ML1::GFP:AP1 (B), and ML1::GLFY, ML1:LFY:GFP and
ML1::GFP:LFY (C) probed with anti-GFP antibody. Extract of wild-type
Col-0 seedlings was used as a negative control in A. Blots were deliberately
overexposed to reveal the presence of any minor bands. No major degradation
products in the form of single GFP were found. Bands detected at higher
molecular weight in the 2xGFP and GLFY lanes probably represent dimers
formed during the extraction procedure. In B, GFP:AP1 bands are marked with an
arrow and the minor single GFP band in GFP:AP1 is marked with an
arrowhead.
