- Steinebrunner I, Landschreiber M, Krause Buchholz U, Teichmann J, Rödel G. HCC1, the Arabidopsis homologue of the yeast mitochondrial copper chaperone SCO1, is essential for embryonic development. J Exp Bot. 2011;62:319-30 pubmed publisher..Growth of the complemented yeast mutant was enhanced by the addition of copper to the medium. The data demonstrate that HCC1 is essential for embryo development in Arabidopsis, possibly due to its role in cytochrome c oxidase assembly. ..
- Krämer U. MTP1 mops up excess zinc in Arabidopsis cells. Trends Plant Sci. 2005;10:313-5 pubmed..They demonstrate that the mtp1-1 mutant is hypersensitive to zinc and complement the mutant by transforming it with the MTP1 coding sequence downstream of a constitutive (35S) promoter. ..
- Ihnatowicz A, Pesaresi P, Lohrig K, Wolters D, Müller B, Leister D. Impaired photosystem I oxidation induces STN7-dependent phosphorylation of the light-harvesting complex I protein Lhca4 in Arabidopsis thaliana. Planta. 2008;227:717-22 pubmed..Thus, under extreme redox conditions, hyperactivation of thylakoid protein kinases and/or reorganization of thylakoid protein complex distribution increase the susceptibility of PSI to phosphorylation. ..

Plant J. 2010;64:668-78 pubmed publisher..We show that LOM1 and LOM2 promote cell differentiation at the periphery of shoot meristems and help to maintain their polar organization...
