Table 3 Correlation between GFP accumulation levels and PB presence in plants expressing GFP, GFP-ELP and GFP-HFBI

From: Protein body formation in stable transgenic tobacco expressing elastin-like polypeptide and hydrophobin fusion proteins

Accumulation level of GFPa PBs
Absence Presence
Less than 0.2% TSP 20 0
More than 0.2% TSP 4 36
  1. a, In total, 60 transgenic lines were analyzed by laser scanning confocal microscopy to determine presence or absences of PBs. Three leaf samples per plant were analyzed including one young leaf, one medium-sized leaf and one old leaf.
