| Abstract: Active oxygen species ( AOSs ) are produced under stress conditions of plant cells .
Superoxide dismutase ( SOD ) catalyzes the first step in the AOS scavenging system .
The responses of SOD genes to environmental stresses were analyzed in rice seedlings by the treatments of drought , salinity and chilling .
The expressions of abscisic acid ( ABA ) -inducible genes , Mn-SOD gene ( sodA1 ) and one of the cytosolic Cu/Zn-SOD genes ( sodCc2 ) , were strongly induced by the treatment of drought and salinity .
While Fe-SOD gene ( sodB ) and the other cytosolic Cu/Zn-SOD gene ( sodCc1 ) were also induced by ABA .
However the mRNA level of sodB was decreased by drought treatment , and sodCc1 gene was not induced by drought and salinity treatments .
Plastidic Cu/Zn-SOD gene ( sodCp ) quickly responded to salinity treatment in the light but not in the dark .
In the treatment with hydrogen peroxide , sodCp gene was strongly induced shortly after the treatment .
These results suggested that phytohormone and AOSs are associated with the regulation of SOD genes under environmental stresses . |
