Cell signaling in marine diatoms.

摘要: Marine photosynthetic microorganisms (phytoplankton) are the basis of marine foodwebs and responsible for nearly 50% global annual carbon-based primary production.1 Phytoplankton can grow rapidly form massive blooms that be regulated by environmental factors such as nutrients light availability biotic interaction with grazers viruses.2,3 Their crucial role in drawing down atmospheric CO(2) their potential use future biofuel production4 raises critical need better understanding fundamental features biology.5 Although traditionally phytoplankton were considered passive drifters currents (from Greek-"Planktos"), our recent reports demonstrate how cells employ a complex mechanism to sense changes cues activate chemical-based defense strategies.
