[bcn_evodevo] Evo-Devo Seminar by Per Ahlberg on Monday 16th December 12:00

by James Sharpe

Dear All, On Monday 16th December at 12:00 at the PRBB (CRG) Per Ahlberg will give a seminar entitled: "Looking in the mirror of evolution: fossils, development and the origin of the jawed vertebrate face" Venue: Marie-Curie Room, PRBB PER AHLBERG, from the Evolutionary Biology Centre at the Uppsala University, Sweden, has two principal fields of research: Palaeozoic vertebrate evolution with focus on the origin of tetrapods - the morphological transition from fish to tetrapod - and the relationship of molecular and developmental patterning to morphological evolution. Specifically he is looking into the evolution of muscles and bones in vertebrate heads, necks and limbs, bringing together molecular techniques such as transgenic cell lineage labeling with palaeontological data in a single analysis. He has been invited by James Sharpe (CRG). Abstract: Facial anatomy differs fundamentally between extant jawless and jawed vertebrates (cyclostomes and gnathostomes). Cyclostomes such as lampreys and hagfishes have a median nasohypophysial duct; gnathostomes such as zebrafish and humans have separate nasal sacs opening externally, and a palatal hypophysis. Premandibular neural crest cells migrate forwards either side of the nasohypophysial placode to form the upper lip in cyclostomes, but between the hypophysial and nasal placodes to form the trabecular region in gnathostomes (1). In cyclostomes the forebrain is much shorter than in gnathostomes and the hypophysis is relatively anterior. A series of fossils belonging to the gnathostome stem group bridges the gap between these facial architectures and provides a surprisingly detailed account of the evolutionary and developmental transformation of the vertebrate face. The most basal of these is the galeaspid Shuyu, a 430 million year old jawless stem gnathostome (2). Shuyu has a nasohypophysial duct, short forebrain, and anteriorly oriented hypophysis, but the nasal sacs and hypophysis are separated by a rudimentary trabecula. The placoderm Romundina, a 415 million year old jawed stem gnathostome, represents a more advanced transitional step. Its cranial cavity is similar to that of Shuyu, with an anteriorly directed hypophysis and very short telencephalon. The trabecular region is exceptionally long and wide, with proportions similar to a cyclostome or galeaspid upper lip, whereas the nasal capsule (demarcated by a fissure) is small and located far behind the tip of the snout. We interpret these features as uniquely primitive among jawed vertebrates. In slightly more advanced placoderms like Dicksonosteus (3), the trabecular region is shortened anteriorly so that the nasal capsule becomes terminal: a spatialrelationship that is retained in all later jawed vertebrates. We suggest that during the evolution of the gnathostome face, separation of the nasal and hypophysial placodes was followed by loss of the nasohypophysial duct, then by anterior shortening of the trabecular region which placed the nasal capsules in a rostral position, and finally by a lengthening of the entire preorbital face (including the forebrain) without further change in the relative proportions of its components.

by Yogi Jaeger

Dear Bcn EvoDevo Community, This email list has been dead for too long! Here's my feeble attempt to revive it ;-) I am traveling to the NESCent Workshop on the future of EvoDevo in Durham, NC, USA today. The workshop is small but has an online component through which you can contribute and participate in the discussion. If you are interested, please check out the email from Cassandra below. Best, Yogi ---------- Forwarded message ---------- From: <evoldir(a)evol.biology.mcmaster.ca> Date: Sat, Dec 7, 2013 at 9:33 AM Subject: Workshop: NESCent.EvoDevo.Dec11-13 To: yoginho(a)gmail.com Dear Colleague, This email is to invite you to contribute your ideas to upcoming Evo-Devo community workshop supported by the National Science Foundation of the USA. The meeting will take place from 11-13 December 2013 at NESCent in Durham, North Carolina. Although over 300 members of the international Evo-Devo community have expressed interested in attending the meeting, because of funding and infrastructure limitations, unfortunately we could ask only a small number of people to attend the meeting in person. However, due to the level of interest in this workshop, we have tried hard to find ways to get as much community input as possible, and so would like to invite you to ¡§participate virtually¡¨ in the meeting, You can do this in a number of ways: 1. Set up an account for yourself on the meeting website at http://evodevo.ning.com. On this website, you will find an agenda for the program, list of participants who will be physically present at NESCent, be able to view and participate in wiki-style discussions, and keep track of what is happening at the meeting. This website will be updated to document the proceedings of the meeting in real time. 2. Watch some of the presentations and discussions that will take place during the meeting via Webinar. You can also contribute to the discussions at NESCent in real time by sending in your comments and questions via the Webinar interface ¡V these will be communicated to the participants at NESCent by a designated moderator. Instructions on how to access the Webinar can be found on the website indicated in (1) above. 3. Join conference call discussions that will be considering the same issues as those discussed by participants at NESCent during parallel ¡§virtual breakout groups.¡¨ The moderators of these calls will summarize the ideas generated during the call to the group at NESCent. Instructions on how to call in to these conference calls can be found on the website indicated in (1) above. The times and discussion topics for these conference calls are as follows: What distinguishes the field of Evo-Devo, and what unique contributions has it made? Wednesday December 11 at 12:00 EST. Moderated by Paula Mabee. What infrastructure is needed to ensure the continued success of Evo-Devo? Wednesday December 11 at 15:00 EST. Moderated by Jeffrey Marcus. What is the future promise of Evo-Devo, and how can we obtain the resources necessary to realize this promise? Thursday December 12 at 11:30 EST. Moderated by Trisha Wittkopp. What new teaching and training initiatives/materials are necessary for preparing the next generation of Evo-Devo scientists? Thursday December 12 at 15:30 EST. Moderated by Joel Smith. We hope you will ¡§join us¡¨ in as many of these ways as possible. We look forward to your contributions!

[bcn_evodevo] Michel Milinkovitch - Reptilian Transcriptomes - CRG Wed, Jun 12, 3pm

by Yogi Jaeger

Dear Barcelona Evo-Deviants, Toni Gabaldon will be hosting Michel Milinkovitch next week at the CRG. His seminar will be on reptilian phylogenomics and evo-devo (see below). Best, Yogi --- seminar announcement: ---- Wednesday, June 12th, 15:00 h Sala Charles Darwin (PRBB) Reptilian-transcriptomes.org: from phylogenomics to EvoDevo. Michel C. Milinkovitch Laboratory of Artificial & Natural Evolution (LANE) Dept of Genetics & Evolution, University of Geneva, Switzerland. Reptiles are largely under-represented in comparative genomics/transcriptomics despite the fact that they are substantially more diverse in many respects than mammals. We performed deep-sequencing of transcriptomes of divergent reptilian and avian lineages and used in-house software pipelines for recursive similarity searches and homology assignment. Our approach identifies the majority of the reference chicken transcripts and about 50% of de-novo assembled reptilian transcripts. We also identify dozens of thousands microsatellite, SNP, and indel polymorphisms for population genetic and linkage analyses. We build very large multiple alignments (hundreds of thousands residues per species) and generate the first robust large-scale phylogenomic hypothesis for Sauropsida and mammals. Our analyses indicate that turtles are not basal living reptiles but are rather associated with Archosaurians, hence, answering a long-standing question in the phylogeny of Amniotes. We also deep-sequenced in snakes the transcriptome of the vomeronasal organ (VNO), an olfactory structure that detects pheromones and environmental cues. Snakes exhibit a very large VNO associated with a sophisticated tongue delivery system. The predominant V1R and V2R transmembrane chemoreceptor repertoires in tetrapods are believed to detect airborne and water-soluble molecules, respectively. It has been suggested that the shift in habitat of early tetrapods from water to land is reflected by an increase in the ratio of V1R/V2R genes. Our analyses indicate that snakes and lizards retain an extremely limited number of V1R genes but exhibit a large number of V2R genes, including multiple lineages of reptile-specific and snake-specific expansions. These results do not support the hypothesis that the shift to a vomeronasal receptor repertoire dominated by V1Rs in mammals reflects the evolutionary transition of early tetrapods from water to land. Instead, our study reveals how mammals and squamates differentially adapted the same ancestral vomeronasal repertoire to succeed in a terrestrial environment. The reptilian transcriptomes (freely available at http://www.reptilian-transcriptomes.org) should prove useful new resourcea as reptiles are becoming important new models for comparative genomics, ecology, and evolutionary developmental genetics.

[bcn_evodevo] Reminder: Ariel Chipman seminar - CRG, Thu, Jan 31, 4pm

by Yogi Jaeger

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.
