Identification of genes expressed in response to acid stress in Synechocystis sp. PCC 6803 using DNA microarrays.

Plant cells are always exposed to various environmental stresses such as high light, low temperature and acid rain, and thus have to respond in order to survive these stresses. Although some mechanisms of responses to high light and low temperature etc., have been clarified, there is little information about the acclimation process to acid stress.
