TL;DR: These findings establish a common suite of alterations in photosynthetic electron transport that results in decreased linear electron flow when C. reinhardtii is limited for either P or S.

TL;DR: A gene encoding a regulator of phosphorus metabolism, designated Psr1 (phosphorus starvation response), from a photosynthetic eukaryote is described, and immunocytochemical studies demonstrate that this protein is nuclear-localized under both nutrient-replete and phosphorus-starvation conditions.

TL;DR: It is determined that pho84Delta cells have a significant defect in phosphate uptake even when grown in high phosphate media, and a PHO84-dependent compensation response was identified; the abundance of Pho84p at the plasma membrane increases in cells that are defective in other phosphate transporters.

TL;DR: In wild-type seedlings, repair of cyclobutane pyrimidine dimers occurred more slowly in the dark than in the light; repair of this photoproduct was not affected in the mutant.

TL;DR: In this paper, high rates of biological N2-fixation in prokaryotes associated with Sphagnum mosses were demonstrated, indicating that mosses are not limited by N. And they concluded that N2fixation drives high sequestration of C in pristine peatlands, and may play an important role in moderating fluxes of methane, one of the most important greenhouse gases produced in peatland.
