A Widespread Glutamine-Sensing Mechanism in the Plant Kingdom
PII signal transduction protein in Chlamydomonas reinhardtii: localization and expression pattern.
Sequencing and Expression Analysis of the Gene Encoding PII Signal Protein in Chlorella Variabilis NC64A
It is demonstrated that like its plant PII homologs, the C. variabilis PII protein (CvPII) is appeared to be localized in the chloroplast and will facilitate not only characterization of PII signaling network but also the transcriptional analysis in this alga.
The HSP70 chaperone machines of Chlamydomonas are induced by cold stress.
Reduction of PII signaling protein enhances lipid body production in Chlamydomonas reinhardtii.
Chemotaxis to ammonium/methylammonium in Chlamydomonas reinhardtii: the role of transport systems for ammonium/methylammonium
The results suggest that the hat1 mutant could be affected in genes encoding regulatory elements of AMT1 transporter activities and that chemotaxis to ammonium/methylammonium is mediated by ammonium transporters sensitive to the potassium-channel inhibitor TEA.

The data support the idea that in S-deprived cells THB1 plays a dual role in NO detoxification and in coordinating sulfate limitation with nitrate assimilation, and uncovers a new function for the Chlamydomonas reinhardtii ThB1 in the control of proper response to S deprivation.
Interaction of N‐acetyl‐l‐glutamate kinase with the PII signal transducer in the non‐photosynthetic alga Polytomella parva: Co‐evolution towards a hetero‐oligomeric enzyme
Polytomella parva has lost the ability to estimate the cellular energy and carbon status but has specialized to provide an entirely glutamine‐dependent arginine feedback control, highlighting the evolutionary plasticity of PII signalling system.
Glutamine Assimilation and Feedback Regulation of L-acetyl-N-glutamate Kinase Activity in Chlorella variabilis NC64A Results in Changes in Arginine Pools.
Regulation by Light of Chemotaxis to Nitrite during the Sexual Life Cycle in Chlamydomonas reinhardtii
A working model for the signaling pathway by which blue light controls chemotaxis towards attractants, which are nitrogen sources, during pregamete-to-gamete conversion of C. reinhardtii is proposed.
