In photosynthetic organisms, Fur proteins regulate many genes involved in photosynthesis, nitrogen metabolism and other key processes. Also, Fur triggers the expression of virulence factors in many bacterial pathogens, and Fur from Microcystis aeruginosa has been shown to bind promoter regions of the microcystin synthesis gene cluster. In this work, we studied transcriptional responses of fur genes under different light intensities and oxidative stress. An antisense of fur, the α-fur RNA, plays an important role in regulating fur expression under oxidative stress, affecting levels of Fur protein in cells. Importantly, an active photosynthetic electron chain is required for the expression of the fur gene. info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.791 2011 PLANT SCIENCES 43 / 189 = 0.228 2011 Q1 T1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Sevilla, Emma (orcid)0000-0001-6435-3540 González, Andrés Universidad de Zaragoza (orcid)0000-0002-0531-0943 Bes, M.
