PROFESSIONAL FACULTY RESEARCH

(microbiology) Photosynthetic membranes - structure, function, and assembly in cyanobacteria; functional genomics and impact of environmental factors on photosynthesis; analysis of global regulation with microarrays; regulation of photosynthesis and N 2 -fixation in unicellular cyanobacteria.


BIO

Cyanobacteria have become wonderful and versatile model organisms for the study of photosynthesis, nitrogen fixation and responses to environmental stresses. Our research can help answer questions involved with environmental concerns, alternative energy uses (i.e., solar energy), and health concerns such as microbial toxins and the design of new drugs. The genomic sequence of one favorite cyanobacterium was completed a few years ago, and we now have the task of trying to determine the function of each of its 3,264 genes, ultimately to understand how a cell functions. The lab has successfully constructed microarrays ("gene chips")--this is an important technique in biology and all of the genes in an organism can be spotted on a glass slide about the size of a microscope slide. These microarrays are great for studying the activity of genes; this technique, along with the ability to make mutations in virtually every gene, is a key way for determining gene function under different environmental conditions. The genome sequence of another of our favorite cyanobacteria has recently been completed. This unicellular organism shows robust metabolic and circadian rhythms and performs photosynthesis and N 2 -fixation at different times of the day and night. This organism is key to a large project aimed at understanding the regulation of such processes and the assembly of membrane complexes. The genomes of 6 more Cyanothece species are being sequenced at DOE and will aid us in identifying important genes and processes for alternate energy uses.
