  • Binkert M, Kozma-Bognar L, Terecskei K, de Veylder L, Nagy F and Ulm R. UV-B-responsive association of the Arabidopsis bZIP transcription factor ELONGATED HYPOCOTYL5 with target genes, including its own promoter. The Plant Cell, 28 October 2014. DOI: 10.1105/tpc.114.130716. [Open Access]

Though he has a joint appointment at the Hungarian Academy of Sciences, Ferenc Nagy is also SULSA Chair of Cell Biology at the University of Edinburgh. Working with Swiss, Hungarian and Belgian colleagues, this paper describes research to understand the transcription factors regulating plants’ protective responses to UV-B. It is shown that, in Arabidopsis, binding of the bZIP transcription factor ELONGATED HYPOCOTYL5 (HY5) to the promoters of UV-B-responsive genes is enhanced by UV-B independently of the UV-B photoreceptor UV RESISTANCE LOCUS8 (UVR8).
