Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Genome Structure

There has not been a genome project on Rhizosolenia spp. at this time.

Cell Structure, Metabolism and Life Cycle

Rhizosolenia is a unicellular rod shaped diatom and ranges in diameter size from 2.5-170 µm. The cell wall is made of a silica shell comprised of two separate valves, also known as a frustule. The cell can synthesize the biogenic silica needed for the construction of the frustules. In addition the total silica production contributes a siginificant amount in the global marine silica cycle. Rhizosolenia is mostly abundant in a mat formation containing communities of multiple Rhizosolenia species. The mats can be short chains of only a few cells or larger rigid chains ranging from 1-30cm wide.

Ecology and Pathogenesis
