Figure 2From: Efficient production of human acidic fibroblast growth factor in pea (Pisum sativum L.) plants by agroinfection of germinated seedsPercentage of plants expressing GFP after vacuum infiltration of germinated pea seeds with a mixture of Agrobacterium GV3101 strains carrying binary plasmid pCAPE2-GFP and pCAPE-1 respectively. (a) Frequency of transformants with variation of length of vacuum exposure. Series 1, 2, 3 and 4: peas seeds were subjected to vacuum for 1 min, 5 min, 10 min and 15 min. (b) The frequency of GFP expressing plants with increasing vacuum pressure (c) Frequency of GFP expressing plants with wounded and non-wounded roots. (d) The frequency of GFP expressing plants upon treatment with different bacterium suspension densities.Back to article page
