Fig. 6: Structural analysis of light acclimation in Phaeodactylum tricornutum.
a Cells were imaged at two different light regimes: LL (40 µmol photons m−2 s−1, left) and HL (350 µmol photons m−2 s−1, right). Scale bar: 1 µm. b Volume occupancy by the plastids (dark green), mitochondria (red) and pyrenoid (light green) in the two conditions. Data refer to three cells ± s.d. for each growth condition. c Respiratory activities (red) and photosynthetic capacities (green) are indicated for LL (left) and HL (right) cells. Data refer to three biological samples ± s.d. for each growth condition. d Plastid-mitochondria proximity surface points in LL and HL cells, measured at ≤30 nm (grey) and ≤90 nm (black). At both distances, proximity areas points are increased by around 25% (blue) upon HL transition. Data refer to three cells ± s.d. for each growth condition.
