Abstract

Inorganic nitrogen is an essential nutrient for photosynthetic organisms. Its efficient use in nature involves adaptation of the organisms to the availability of the nitrogen supply, to changing environmental conditions, and to the provision of carbon and other nutrients. The unicellular alga Chlamydomonas provides a useful model to identify not only each of the components participating in the assimilative process in a species, but also the regulatory networks modulating their activity. A remarkable fact is the ample array of transporters for inorganic nitrogen compounds operating in this single cell: 13 putative nitrate/nitrite transporters and eight putative ammonium transporters. However, for nitrate, only a few of them participate as the main suppliers of nitrogen for cell growth, and others probably function to adapt nitrogen utilization efficiency to conditions depending not only on the nitrogen source available but also on other nutrients and environmental conditions. This paper summarizes recent findings in Chlamydomonas to provide an integrated perspective.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
