The seminar will take place on Friday May 1st, at 12 pm in MSB-105 (BBC campus). In case anyone wants to attend from MMC, please send me an email to arrange polycom broadcast. Also, please contact me in case you want to meet with Dr. Monroe, there will be plenty of opportunities to interact either before or after the seminar.

As you know, Florida Red Tides constitute a major threat in our coastal areas, causing neurotoxic shellfish poisoning in marine organisms, affecting aquaculture and fishery industries, as well as producing respiratory distress in humans. Since many FIU folks develop active research on different aspects of this dinoflagellate species, this seminar promises to be a great framework for interaction, discussion and hopefully future collaborations!

Overall, a great closing for this year’s seminar series!!!. Many thanks to FIU’s University Graduate School, the Dept. of Biological Sciences, the Dept. of Chemistry and Biochemistry and the Marine Sciences Program for their support. Many thanks to our graduate students for selecting a great representation of top notch speakers for these seminars and to all the speakers who visited our beautiful Miami.

Finally, special thanks to all of YOU who attended the seminars and the social events associated with them. Remember, THAT is what gives this seminar series a reason to be alive for future editions and new generations of students.

We look forward to seeing y’all next year! have a great summer!

BACKGROUND

For more than a century histone proteins, composed of a polymer known as chromatin, have been studied for their role in the physical organization of chromosomes. More recently interest in this complex has been greatly rekindled by the recognition of chromatin’s role in gene regulation, including acquired traits that are inherited without involving changes in the DNA sequence. In other words, chromatin plays a central role in the configuration and propagation of epigenetic information across generations. The rapid increases in “omic” data and analytical methods have provided new approaches for understanding the interaction between genetic and epigenetic information, adding a layer of complexity in DNA regulation that, while still poorly understood, will clearly be important for understanding how cells adapt to changes in external conditions.

The research of Dr. Steve Henikoff (BS University of Chicago, PhD Harvard University) and his team seeks to understand this elusive relationship between chromatin and epigenetic inheritance. Their work has applied pioneering research approaches combining molecular biology, genetics, evolution and bioinformatics to study the different mechanisms potentially encoding epigenetic information (i.e., histone variants and their chemical modifications, DNA methylation, transcription factor regulatory networks, among others). Among these works, the characterization of the mechanisms governing centromeric chromatin structure and evolution are specially groundbreaking, challenging the classic notion stating that our whole genome, our chromosomes, are filled up with nucleosomes and they’re all octamers. In recent years they have expanded their scope from chromatin structure, dynamics and evolution to interactions with other components of the epigenome including nucleosome remodelers, transcription factors and RNA polymerase II*.

Marine Sciences Seminar Series, Fall 2014

Posted by | Education, FIU, Outreach, Research | No Comments

Ready for the Marine Sciences Seminar Series, Fall 2014! We have gathered a great line up of scientists addressing diverse topics of the upmost interest, ranging from biogeochemistry to conservation and restoration of coastal ecosystems, and from fisheries and population dynamics to climate change and marine population genetics. In addition to speakers from our own FIU Marine Sciences Program, we’ll also have the opportunity to get an insight into the research being made at other floridian institutions such as the University of Florida, the Smithsonian Marine Station, Rookery Bay National Estuarine Research Center, etc.

Seminars will take place every other wednesday at noon (starting Sep. 3rd) in room MSB-105 at the Marine Science Building in the Biscayne Bay Campus from FIU (with polycom to HLS-216 at MMC). We want to encourage all of you (regardless of your field of expertise and independently of wether you are faculty, student or staff) to dive with us into these lectures flavored with a bit of sea salt and explore the submarine world around us!

Chromevol’s work cited in the latest book by M. Nei “Mutation Driven Evolution” (Oxford University Press)

Posted by | Education, Evolution, Gene Families | No Comments

Ever since the inception of the Modern Synthesis (the combination of Darwin’s Theory of Evolution by means of Natural Selection and the laws of genetic inheritance by Gregor Mendel) the role of natural selection shaping the variation observed in populations has represented one of the most attractive topics in Biology. However, evolution is driven by other additional forces, most notably mutation (the most important source of genetic variation). In this instant classic, Professor Masatoshi Nei examines the different mechanisms by which mutation contributes to evolution. Prof. Nei’s research has constituted a constant inspiration for our work at Chromevol, so we are specially proud that our own research on the evolution of multigene families is cited in this book.
