Dear Colleagues, It is with great pleasure that we welcome you to Duke University and the 9th International Biometals Symposium, BioMetals 2014. Our conference includes 170 international participants from over 25 countries on 5 continents. The conference format consists of 27 invited lectures, 34 contributed short talks, and over 120 posters. As always in the BioMetals conference series, our interdisciplinary theme is the exploration of metals in biology, medicine and the environment. BioMetals 2014 offers several subthemes: metal homeostasis in plants, metals at the host-pathogen interface, mechanisms for metal acquisition, metal cofactors, metal dependent signaling, metals in health and disease, environmental biology of trace metals, and metals in biotechnology.
During the course of the conference several awards will be given that will recognize outstanding graduate student and postdoctoral associate presentations including the Jorge Crosa awards. The International Biometals Society will also recognize the Heritage Award winner. The Igor Stojiljkovic Memorial Award will be presented to Shelley M. Payne, who will give the closing conference lecture.
We hope that you will take the opportunity on Monday evening and Wednesday afternoon and evening to explore the beautiful Duke University campus and the heart of Durham. The American Tobacco Campus, Brightleaf Square, Ninth Street, and the city center each offer a different atmosphere and interesting restaurants. We are highlighting an all-star baseball game and cookout on Wednesday, as well as other options, on and off campus, which will be suggested during the conference.
We thank the International Scientific Committee, Larry Barton, Pierre Cornelis, Manuel Lemos, Nigel Robinson, Isabelle Schalk, Hans Vogel, and Guenther Winkelmann, for their advice in designing the scientific program. We are grateful for the administrative assistance of Christiana Conti of the Duke Chemistry Department for her dedication and skill in synchronizing all aspects of this conference. We also thank our Duke volunteers for their assistance. We greatly appreciate financial assistance from our corporate and university sponsors, whose names are listed in the program. Most importantly, we thank you for your participation in making BioMetals 2014 a successful conference.
Best wishes, Al Crumbliss Kathy Franz Dennis Thiele Claire Siburt

During zinc limitation, Chlamydomonas hyperaccumulates copper in a pathway dependent on the nutritional copper sensor Crr1. Nevertheless, the cells are functionally copper-deficient, suggestive of copper compartmentalization. Visualization of intracellular Cu(I) reveals distinct foci of Cu(I) accumulation, similar in size to electrondense structures and coincident with lysosome and polyphosphate staining, suggesting that they are lysosome-derived compartments. Both NanoSIMS and fluorescent staining show colocalization of Ca and Cu to these sites, named cuprosomes. X-ray absorption spectroscopy (XAS) of Cu(I)-accumulating cells is consistent with Cu(I) organized in an ordered structure with N, O and S ligands. Zinc resupply restores copper homeostasis and is concomitant with reduced abundance of cuprosomes. Isotope labeling experiments demonstrate that the previously-sequestered Cu(I) becomes bioavailable for the synthesis of cuproproteins like plastocyanin, and transcriptome profiling indicates that mobilized Cu(I) becomes visible to Crr1. Copper-trafficking to cuprosomes may be a strategy for both preventing protein mis-metallation during zinc deficiency and efficient cuproprotein (re)-metallation upon zinc resupply.
