TABLE 2.

Expression of genes related to folate synthesis and nitrogen metabolism in exFTL compared to wild type (WT).

Synechocystis cultures of WT and exFTL were cultivated at ambient air supplemented with 10 mM sodium formate or without. Samples from WT and exFTL for RNA isolation were taken after 3 days. Results are given as relative transcript levels normalized to WT without formate addition. Changes that are exceeding the threshold are marked in red. Genes that show strong formate-dependent changes in exFTL are marked in yellow (*p < 0.05 to the respective WT sample).
