“As such they are well suited as intracellular sunscreens, particularly in oxygenic phototrophic symbioses.”

“We have argued that more than the alga's, it is the host's metabolism that has had to adjust to the conditions of phototrophic endosymbiosis.”

“By contrast, no linkage was detected in crosses with the five class II mutant strains since phototrophic recombinants were recovered at high frequency.”

“An autotroph is photoautotrophic if light energy is required to assimilate CO2 into the organic constituents of the cell.”

“The term phytoplankton encompasses all photoautotrophic microorganisms in aquatic food webs.”
