SPX-related genes regulate phosphorus homeostasis in the marine phytoplankton, Phaeodactylum tricornutum

Abstract

Kaidian Zhang et al. identify SPX-containing genes in the phytoplankton, Phaeodactylum triconutum, and examine their contribution toward phosphorous regulation. Their results suggest that SPX is a negative regulator of phosphorous uptake, providing a better understanding of how phytoplankton adapt to phosphorous availability in the oceans.
