The Impacts of Phosphorus Deficiency on the Photosynthetic Electron Transport Chain.

abstract：:Expression of the Em gene was characterized in rice (Oryza sativa L.) suspension cultures following exposure of the cultures to various combinations of abscisic acid (ABA) and salt. Response-saturating concentrations of either ABA (50 micromolar) or NaCl (0.4 molar) rapidly induced (by 60 minutes) the accumulation of ...
