      abstract     = {Concomitant increases in O(2) and irradiance upon
                      de-submergence can cause photoinhibition and photo-oxidative
                      damage to the photosynthetic apparatus of plants. As energy
                      and carbohydrate supply from photosynthesis is needed for
                      growth, it was hypothesized that post-submergence growth
                      recovery may require efficient photosynthetic acclimation to
                      increased O(2) and irradiance to minimize photo-oxidative
                      damage. The hypothesis was tested in two flood-tolerant
                      species: a C(3) herb, Alternanthera philoxeroides; and a
                      C(4) grass, Hemarthria altissima. The impact of low O(2) and
                      low light, typical conditions in turbid floodwater, on
                      post-submergence recovery was assessed by different flooding
                      treatments combined with shading.Experiments were conducted
                      during 30 d of flooding (waterlogging or submergence) with
                      or without shading and subsequent recovery of 20 d under
                      growth conditions. Changes in dry mass, number of
                      branches/tillers, and length of the longest internodes and
                      main stems were recorded to characterize growth responses.
                      Photosynthetic parameters (photosystem II efficiency and
                      non-photochemical quenching) were determined in mature
                      leaves based on chlorophyll a fluorescence measurements.In
                      both species growth and photosynthesis recovered after the
                      end of the submergence treatment, with recovery of
                      photosynthesis (starting shortly after de-submergence)
                      preceding recovery of growth (pronounced on days 40-50). The
                      effective quantum yield of photosystem II and
                      non-photochemical quenching were diminished during
                      submergence but rapidly increased upon de-submergence.
                      Similar changes were found in all shaded plants, with or
                      without flooding. Submerged plants did not suffer from
                      photoinhibition throughout the recovery period although
                      their growth recovery was retarded.After sudden
                      de-submergence the C(3) plant A. philoxeroides and the C(4)
                      plant H. altissima were both able to maintain the
                      functionality of the photosynthetic apparatus through rapid
                      acclimation to changing O(2) and light conditions. The
                      ability for photosynthetic acclimation may be essential for
                      adaptation to wetland habitats in which water levels
                      fluctuate.},
