Target species - IMAGO

Life originated and mainly differentiated in the sea. The now living marine organisms represent the most diverse and unique genomes, life-supporting systems and biological mechanisms amongst all living organisms.

Besides increased demands for understanding genetic and molecular mechanisms of physiological and evolutionary changes under global change, the unique genomes of many marine species represent an invaluable untapped resource for biotechnology and medical research.

In 2011 CeMEB launched IMAGO – Infrastructure for MArine Genetic model Organisms. Under IMAGO we will develop 8 marine species into new experimentally amenable genetic models. The chosen species represent key-species in NE Atlantic coastal ecosystems.

We plan to publish genomes during 2016-2017. Prior to the genome publication, the access to the current assembly data for a particular species can be arranged in terms of a collaborative project. If you are interested in such collaboration, please contact the project coordinators Kerstin Johannesson and Anders Blomberg.

The 8 IMAGO species

Table updated: 2016-09-07

Amphiura filiformis

 

Brittlestar, echinoderm
Has the capacity to regenerate arms and is an emerging model for regeneration and stem cell biology in biomedical research

In progress

 No

 

Balanus improvisus

 

Barnacle, crustacean arthropod
Is an important fouling organism and a potential source for various areas of biotechnological research

Draft assembly

 

EST
RNA-seq
PacBio

Proteomics
Microsat
COI

 

Yes

 

Debaryomyces hansenii

 

Marine fungus
A marine yeast that occurs globally with extreme tolerance to salt/dehydration stress.

 

Population resequencing

Phenomics

Yes

 


Fucus vesiculosus

 

Bladderwrack, marine macroalgae
Has extensive morphological and ecological variation among populations in which several cases show large genetic and chemical differences.

In progress

 

-

 

RAD Seq

 

 No

 

Idotea balthica

 

Isopod, crustacean arthropod
Is an ecosystem engineer which increases productivity of seagrass beds (Zostera) by reducing epiphytes, and a documented controlling influence on the macroalgae Fucus vesiculosus. As a food source in itself I. baltica is a major part of the diet of many fish species, including the commercially important fishes.

In progress

 

RNA Seq

 

RAD

 Yes

 

Littorina saxatilis

 

Rough periwinkle, gastropod mollusc
Is strongly polymorphic and distinct ecotypes evolve repeatedly in contrasting microhabitats. This species is considered to be one of the rare examples of speciation in the presence of gene flow (sympatric speciation).

RNA-seq through collaboration
 

RAD Seq

Microsat

Phenomics

 

 Yes

 

Pomatoschistus minutus

 

Sand goby, bony fish
Is euryhaline i.e. it is able to adapt to a wide range of salinities, however, not to fresh water. Sand goby life stages from pelagic fry to adults are staple food for cod and other large commercial fishes.

RNA-seq

 

RAD Seq

 

 No

 

Skeletonema marinoi

 

Diatom, phytoplankton
Generation time is 24 hours which makes it ideal for studies of phenotypic response. Benthic cells act as a resting stage, and can survive for at least hundred years and provide a short-term evolutionary archive in sediments.

In progress

 

RNA-seq

 

Phenomics

Microbiome

 

 Yes

 

The IMAGO infrastructure will consist of:

  • Cultures of each species
  • Full genome sequence information at least partly annotated
  • Genetic tools (morfolino, RNAi etc.) developed for some of the species
  • Routines for phenotype characterisation (proteomics, metabolomics, imaging)
  • An open-access database for storage and display of all information
     

The IMAGO initiative is funded by VR, Formas, University of Gothenburg (through the CeMEB grant)



 

Tissue banks

We keep a tissue bank, at -70˙C, of:

6000 Atlantic cod (Gadus morhua)
2000 Atlantic herring (Clupea harengus),
500 sprat (Sprattus sprattus) and
1000 periwinkle, Littorina saxatilis tissue samples.

For most of the samples there is also extracted DNA in storage.
