Focus

Expression of early segmentation genes eve and gt in a Drosophila embryo
Expression of early segmentation genes eve and gt in a Drosophila embryo

The lab pursues four interrelated research themes:

  1. Molecular population genetics and evolution (Drosophila and Arabidopsis)
  2. Functional evolution of cis-regulatory sequences (Drosophila)
  3. Canalization in development and evolution (Drosophila)
  4. Evolutionary dynamics of disease resistance and pathogenicity (Arabidopsis)

News

October 2011

Misha and Manu have joint force (developmental biology + live imaging + quantitative image analysis) to tackle the question "is there a boundary to transcriptional enhancers?" Enhancers were identified as the minimal piece of sequence that can reproduce the endorgenous expression pattern and for historical reasons, their physical boundaries were "defined" by the restriction enzyme cutting site or pcr primer locations, both of which used by researchers to test difference pieces. Later people have found additional transcription factor binding sites outside these "minimal elements". They are not essential for "producing the expression pattern" in a reporter assay, which is qualitative and doesn't examine the fitness results. Do those additional binding sites matter? How? Check out here: PLoS Genetics

August 2011

Congratulations to Cecelia for assuming a faculty position at the Augustana College at Sioux Falls, SD. She has been such a wonderful colleague and a spiritual core of the lab. We'll surely miss her a lot and best wishes for her new lab!

Also leaving the lab are Levi Barse and Desiree Dickerson. Levi has started as a technician in the lab and over the two year period he has contributed significantly to the project of fly models for diabetes. Desiree was an undergraduate research assistant and has done an honor's thesis work in the kreitman lab. Congratulate both for getting to their next position and good luck for their future!

July 2011

Cecelia Miles' collaboration with Jun Ma's group on the scaling of Bicoid gradient in artificially selected lines for egg size has been published in the journal of Development. Check out it here! pubmed

April 2011

Bin He's work on the role of positive selection in transcription factor binding sites turnover has been published on PLoS Genetics. Check out here. pubmed

Jan 2011

John Reinitz's group joined our department from their previous location in Stony Brooks University. We now created a Kreinitz lab, which is officially up and running! The joint force of evolution + mathematical modeling of enhancer function will surely be super cool! Be sure to follow our latest news!

December 2010

Susan Lott's work on mapping genetic locus underlying pattern formation differences between drosophila species has been published on EVOLUTION. Check out here. pubmed

July 2010

Cecelia's work on artificial selection on egg size causing detectable differences in expression patterning got accepted and published in EVOLUTION. Check out the story! pubmed

June 2010

Congratulations to our graduates! Sarah Carl is headed to Cambridge and Anna McGeachy is headed to Johns Hopkins. Go Class of 2010!! Welcome our new students from The College, Reece DeHaan, Desiree Dickerson, and David Gittin!
