Hi Evo-Devo People, Just a quick reminder that Ariel Chipman's seminar will be today at 16:00h, at the PRBB (Charles Darwin Room, ground floor). Ariel has done some extremely interesting work, systematically dissecting the upper tiers of the segmentation gene cascade in the milkweed bug, Oncopeltus fasciatus, a very promising emerging model system for hemipteran insects. Hope to see you there! Best, Yogi ________________________________________ From: Yogi Jaeger Sent: Thursday, January 24, 2013 3:34 PM To: bcn_evodevo(a)lists.crg.es Subject: Ariel Chipman seminar - CRG, Thu, Jan 31, 4pm Dear Barcelona Evo-Devoists, The following seminar at the CRG may be of interest to you: ARIEL CHIPMAN Dept. of Ecology, Evolution & Behavior, The Alexander Silberman Institute of Life Sciences, The Hebrew University of Jerusalem, Jerusalem IL "The evolution of insect blastoderm patterning - insights from the milkweed bug Oncopeltus fasciatus" Systems Biology Programme Seminar 31/01/2013 at 16:00h, Charles Darwin Room (PRBB, ground floor) Host: Yogi Jäger (CRG) Abstract: The insect body plan is conserved and stereotypical. However, it is becoming increasingly clear that the embryonic processes leading to this conserved body plan are highly variable. We have been studying the early embryonic patterning in the milkweed bug Oncopeltus fasciatus, with the aim of understanding the earliest processes involved in laying out the insect body plan. We have looked at three separate patterning systems – the gap gene network, the head patterning network, and the terminal system – and analyzed the expression and function of key candidate genes, as well as the interactions between them. Using this data we are starting to assemble a full picture of the early blastoderm patterning network, with the aim of determining which aspects of this network are conserved and which are more variable in insect evolution. Please let me know if you would like to chat with this speaker before or after his seminar.
