Increased aluminum exposure induces widespread changes in silicon, carbon, and nitrogen metabolism in Entomoneis vertebralis.

ABSTRACT:

Background

Diatoms are a class of algae that play an essential role in global ecology and produce valuable chemicals. They are known for forming intricate nanostructured silica cell walls (frustules). The introduction of non-siliceous elements like aluminum into diatoms induces properties such as a lower dissolution rate of the frustule, increasing the specific surface area of the frustule and enhancing metabolism. Previous studies have focused primarily on characterizing physiological impacts, leaving the genetic response(s) to non-siliceous elements largely unexplored.

Results

This study investigates the transcriptional response of the pennate diatom, Entomoneis vertebralis to dissolved aluminum. Our findings reveal that in the presence of added 10 µM aluminum, biogenic si
