Multiple Choice

Experiments with marine samples containing Prochlorococcus and other microorganisms showed that gene expression in non-photosynthetic organisms mirrored the diurnal oscillation pattern exhibited by Prochlorococcus, which is photosynthetic. What explanations did the researchers suggest for the diurnal expression pattern in the non-photosynthetic members of the community? Please select all that apply.

A) Gene expression in regulated by salt in the environment
B) Gene expression is regulated by nutrient availability
C) Gene expression depends on photosynthesis in Prochlorococcus
D) Gene expression is temperature regulated
