DESCRIPTION:The first row transition metals like iron\, copper and mangane
 se are nutritionally essential because they are used in bioenergetic syste
 ms to catalyze redox reactions\, which are the basis for life. The bioavai
 lability of these elements has changed over the few billion years since th
 e origin of life so that the growth potential of many organisms can be lim
 ited by mineral nutrition. Accordingly\, organisms have devised mechanisms
  to survive transient and even sustained deficiency. The mechanisms involv
 ed in maintaining copper and iron homeostasis in Chlamydomonas will be pre
 sented. Use of state of the art RNA-Seq methodology to characterize the Ch
 lamydomonas transcriptome will also be presented. The analyses indicate pr
 eviously unknown modifications of the photosynthetic apparatus and the pot
 ential for modification of bioenergetic pathways.\n\nhttp://www.chem.ucla.
