Differential expression of the glucose transporter gene glcH in response to glucose and light in marine picocyanobacteria.

ABSTRACT:

Background

Our team discovered that Prochlorococcus can take up glucose, in a process that changes the transcriptional pattern of several genes involved in glucose metabolization. We have also shown that glcH encodes a very high affinity glucose transporter, and that glucose is taken up by natural Prochlorococcus populations. We demonstrated that the kinetic parameters of glucose uptake show significant diversity in different Prochlorococcus and Synechococcus strains. Here, we tested whether the transcriptional response of glcH to several glucose concentrations and light conditions was also different depending on the studied strain.

Methods

Cultures were grown in the light, supplemented with five different glucose concentrations or s
