data revealed that Glu levels were not affected by
treatment in normally seeded fruits (Figure 4). The
same was true for glutamine (not shown).
A major difference between control and HT
plants was the 80-fold higher ammonium content
in the pericarp from HT plants (Table 2). Ammonium
concentration was close to 7.5mM in control
fruits (Davies and Hobson, 1981; Baldet et al.,
2002), but was equivalent to 600mM in HT plants.
Total ascorbate (AsA+dehydroascorbate) was
strongly decreased and in a more oxidized state in
fruits from HT than control plants (Table 2).
Lycopene, another major antioxidant of tomato
fruits, was also decreased by 30% (Table 2)
