Environmental occurrence of the algal morphogen thallusin and identification of Algoriphagus species as producers in the Baltic Sea (Kiel Fjord, Germany)
Marine macroalgae rely on interactions with associated bacteria for growth and development. In Ulva species, bacterial morphogens such as thallusin are essential for normal morphogenesis, yet their occurrence in natural coastal environments remains poorly understood. Here, we investigated spatial and seasonal varia...
