摘要：

The cytM gene for cytochrome c(M) was previously found in Synechocystis sp. PCC 6803. Northern blotting analysis revealed that the cytM gene was scarcely expressed under normal growth conditions but its expression was enhanced when cells were exposed to low temperature or high-intensity light, By contrast, the expression of the genes for cytochrome c(6) and plastocyanin was suppressed at low temperature or under high-intensity light. These observations suggest that plastocyanin and/or cytochrome c(6), which are dominant under non-stressed conditions, are replaced by cytochrome c(M) under the stress conditions.
