Physiology responses to experimental iron warming interactions of coastal and oceanic Synechococcus collected from the South China Sea

The unicellular cyanobacterium Synechococcus is one of the most important primary producers in the ocean, and its growth and distribution are regionally limited by iron (Fe) concentration and temperature. However, the potential interactions between Fe availability and ocean warming in Synechococcus remain largely unexplored. We cultivated coastal (XM24) and oceanic (YX04-1) Synechococcus isolates from South China Sea under a matrix of two Fe concentrations (2 nM, 250 nM) and temperatures (24°C, 27°C) to investigate their physiological and transcriptomic responses. This dataset includes the sample identifier, strain information, iron and temperature treatment information, normalized iron quotas, carbon fixation rates, particulate organic nitrogen, and particulate organic carbon measurements. This experiment was performed at the University of Southern California in Dr. David Hutchins’s lab from July to December of 2020.
