Schedule last updated on 29 June 2005
REGISTRATION CLOSED since APRIL 1

 

Scientific committee : Dave Scanlan (U. Warwick, UK, EU programme Margenes coordinator), Frédéric Partensky (CNRS Roscoff, France, Local symposium organizer), Wolfgang Hess (U. Freiburg, Germany), Chris Bowler (Statione Zoologica di Napoli, Italy & ENS Paris, France), Anton F. Post (U. Jerusalem & IIMS Eilat, Israel), Peter Kroth (U. Konstanz, Germany) and Pascal-Jean Lopez (ENS Paris, France)

 

Rationale: Marine phytoplankton produce nearly half of the oxygen we breathe, about the same as that produced by land plants. Until recently what we knew of the molecular biology of these important marine microbes was limited to only a few genes in a small number of model organisms which was giving only a limited view of the biological potential and physiology of these organisms. The recent development of genomic technologies has led to a multiplication of genome sequences of marine photosynthetic microbes. Thus, around a dozen organisms representing the most ecologically relevant classes of phytoplankton found in the marine environment (diatoms, coccolithophorids, chlorophytes [green microalgae], and cyanobacteria) have had their complete genomes deciphered. This remarkable resource is allowing us to obtain completely new insights into the biological potential of these organisms. This genomic revolution will also undoubtedly give us new clues helping to explain how these organisms have become so successful in this oceanic environment. Going hand in hand with this genomic data is the development of transcriptomic, proteomic and mutagenesis approaches helping to disentangle gene function, and investigate global changes in gene expression as a result of environmental change.

This symposium will be the first international conference focused on the Genomics of Marine Phytoplankton. It will present the major outcomes of the European Union program Margenes (2002-2005) which aimed at studying "Marine phytoplankton as novel model organisms for genomic and post-genomic studies of environmental sensing and niche adaptation". It will bring together some of the leading experts in the field in Europe and USA, allowing a thorough presentation of the current state of the art, whilst also being a vehicle to discuss and set the major future research directions in the field such as systems biology of the minimal photosynthetic cell, evolution of whole genomes, etc.

Instructions for registered people :

Registered people must now download the final participant list in order to complete the following informations:

- speakers and poster presenters : please provide authors, title and a short abstract (< 200 words)

- all participants : please calculate the total price of your meals (and hotel for Margenes partners) using the Excel file by replacing the prefilled columns by either zero or the relevant price (12,60 € for lunch, 17,50 € for dinner, 38,10 € for banquet).

The total computed in in column AS (or AT for Margenes people with hotel included)

- if you wish to participate in the excursion (afternoon trip to Batz Island), please include the picnic price (cold meal =12,60 €) and the boat shuttle price (5€ return ticket)

   in your calculation.

Note that on July 8, the dinner will be a buffet with a variety of foods and should convene almost everybody.
All other meals will be as follows : entrée, either meat/vegetables or fish/vegetables, cheese, dessert, coffee and wine.
The banquet on July 10 will be mainly seafood (shellfish, fish), but alternative meals can eventually be proposed.

Please send these informations back to partensky@sb-roscoff.fr by May 9!
  
Once checked, you will then be requested (for logistics reasons) to pay in advance the meals (dinners, lunches, banquet) you have selected
(by June 17!)  by faxing (not by email, please) your credit card information (card type, first  and last name, card number, expiration date)
directly to :

Ms. Nicole Sanseau

Station Biologique
BP 74
29682 Roscoff cedex                     
Phone:  (33) 2 98 29 23 98

Fax :     (33) 2 98 29 23 96 (direct)

e-mail : sanseau@sb-roscoff.fr

Any problem, please contact her directly.

At your arrival in Roscoff on July 8, you will receive tickets for those meals you have paid for.

Presentations

Posters should preferentially fit within 0.90 m (width) x 1.20 m (height).
Talks should be presented as Powerpoint file compatible with Microsfot Office Powerpoint 2003

Accomodation: Hotels can be found in town in the attached file or on line at the following address:

http://www.roscoff-tourisme.com/index.php/content/view/full/1967/. We also recommend the IBIS hotel ("Le Corsaire") which is located on the church place nearby the Station Biologique. Note that the Hotel de France (depending from the Station Biologique) was reserved to pre-booked scientists (invited speakers and Margenes participants) and no space is left. Please book hotels by yourself early enough (preferentially before April) because July is the high season for tourism in Roscoff. Do not book hotels before you have received confirmation by F. Partensky that there is space left to participate to the congress.

 

Transportation:

If you come by train from Paris, you will have to get down in Morlaix, then change for a local train or a bus to Roscoff

Please note that all trains from Paris do not have connections to Roscoff, so please check that point

on the SNCF (French railways) web site before buying your tickets.

There is no direct buses nor easy train transportation from the Brest airport (Guipavas) to Roscoff. So you will have to take a taxi (or rent a car). 

Special  fares for taxis can be obtained by using "Taxi Le Pors"

email : anne.laurent.lepors@free.fr
phone # 02 98 19 12 34  or   02 98 67 00 00 ; mobile phone # 06 60 98 17 48   or   06 85 18 37 10 or   06 88 79 46 77
You can also book your taxi directly online at  taxi.lepors.free.fr
Emails sent to the previous address  taxigoarnisson@aol.com have been forwarded to the new owner, so no need to send your email again

Please contact them by email well in advance (several weeks) and provide them with your arrival and departure dates and times as well

as flight numbers so that they can arrange eventual multiple transportations (for several participants at a time).

This would allow to significantly reduce costs per person : cost per taxi is 69 € one way for 1-4 persons and 79 € for 5-8 persons (minibus)

during week days from 7 a.m.-7 p.m. (or 83/93€ during week ends all times or during week days from 7 p.m.-7 a.m.).

Precise in your message that you wish this special fare (for the Station Biologique de Roscoff).
