carbohydrates fully recovered in all types of plants after 7 d of de-submergence ( Yu et al., 2012 ). The submergence-tolerant M202 ( Sub1 ) and sensitive M202 rice ( Oryza sativa ) lines had similar levels of decreased photosystem II photochemistry and

sensing and signaling networks play a major role in developmental programs that generate new tissues ( Pfalz et al., 2012 ). Three different PR classes have been identified in plants based on the chemical nature and photochemistry of their chromophores: 1

radiation is energy associated with wavelengths of visible light (400–700 nm) predominately absorbed by leaf tissues. Photochemistry in plants is initiated by absorbed quanta, which differ in quantum energy level and absorption capacity of photosynthetically

= 1000 μmol·m −2 ·s −1 ). Chlorophyll fluorescence of dark-adapted leaves (dark-adapted overnight using tin foil) was measured to estimate maximum capacity for photochemistry of PSII (F v /F m ). Net photosynthesis (A N ), g S , and E were also measured

saturating pulse of radiation (5000 μmol·m −2 ·s −1 ) was then applied for 0.7 s to determine the maximal fluorescence in the dark-adapted state (F m ), and the maximum quantum efficiency of PSII primary photochemistry [F v /F m = (F m − F 0 )/F m ] was
