FIGURE 2

Photosynthetic fluorescence parameters of transplastomic tobacco plants overexpressing Trx f or Trx m. (A) Maximal photosystem II photochemical efficiency in tobacco plants (Fv/Fm). (B) Effective photosystem II yield (ΦPSII). (C) Non-photochemical quenching (NPQ). Light response curves are shown for ΦPSII (B) and NPQ (C). Measurements were achieved in leaves from 35-day-old Wt and transplastomic tobacco plants grown in standard conditions. Data are mean values ± SD from at least five independent measurements per genotype. Wt, wild-type; Trx f+ and Trx m+, plants overexpressing Trx f or Trx m, respectively. ***Significantly different from Wt with p < 0.001 (t-test).
