Abstract
In this study,the role of carbon monoxide(CO) on reducing cell death rate of rice suspensioncultured cells was investigated under salt stess.The cell death rate increased with the increasing of NaCl concentration(0-400 mmol·L-1) and time(3,6,12 and 24 h).Pretreatment with 50% saturation of exogenous CO aqueous solution for 3 h was able to significantly alleviate the elevating cell death rate induced by further 200 mmol·L-1 NaCl treatment.Meanwhile,the above cytoprotective effect of CO could be reversed by the addition of hemoglobin(Hb),a scavenger of CO.Furthermore,the activities of superoxide dismutase(SOD),catalase(CAT) and ascorbate peroxidase(APX) or their related transcripts were also induced by CO in different degrees.
