The CINNAMON project will analyse how one of the most abundant photosynthetic organisms in the marine environment – Synechococcus cyanobacterium – adapts to iron deficiency in a context of global change.

The project will use a multi-scale (gene to global ocean), comparative approach to study the response of the Synechococcus model to two environmental factors – availability of iron and temperature – by focusing on 3 principle areas:

  • Physiological studies of the effects of iron deficiency and/or temperature on strains that are representative of environments whether these are limited in iron or not.
  • Genomic and transcriptomic comparison to decipher the genetic basis of adaptability to changes in temperature and availability of iron and the role of metabolism and regulation in the capacity of the tested strains to adapt.
  • Meta-omic analyses to identify the genes potentially involved in the acclimatisation (physiology) and adaptation (evolution) of natural populations of Synechococcus to iron deficiency and temperature variations.
