  • Title: An ecological and evolutionary context for integrated nitrogen metabolism and related signaling pathways in marine diatoms.
    Author: Allen AE, Vardi A, Bowler C.
    Journal: Curr Opin Plant Biol; 2006 Jun; 9(3):264-73. PubMed ID: 16603409.
    Abstract:
    Whole-genome sequence analysis has revealed that diatoms contain genes and pathways that are novel in photosynthetic eukaryotes. More generally, the unique evolutionary footprint of the chromalveolates, which includes a genome fusion between a heterotrophic protist and a red alga in addition to a major prokaryotic influence, has fostered their inheritance of a unique complement of metabolic capabilities. Many aspects of nitrogen metabolism and cell signaling appear to be linked in diatoms. This new perspective provides a basis for understanding the ecological dominance of diatoms in contemporary oceans.
