Chloroplast Methyltransferase Homolog RMT2 is Involved in Photosystem I Biogenesis

The paper identifies RMT2 as a chloroplast methyltransferase homolog involved in photosystem I biogenesis in Chlamydomonas reinhardtii through a high-throughput O2 sensitivity screen.

The chloroplastic phosphate transporter CrPHT4-7 supports phosphate homeostasis and photosynthesis in Chlamydomonas

Effects of linker length on phase separation: lessons from the Rubisco-EPYC1 system of the algal pyrenoid

The paper investigates how linker length affects phase separation in the Rubisco-EPYC1 system of green algae, finding that shorter linkers significantly reduce critical concentrations.

Systematic identification and characterization of novel genes in the regulation and biogenesis of photosynthetic machinery

The paper identifies 70 novel genes involved in photosynthesis regulation and biogenesis using genetics in Chlamydomonas reinhardtii and characterizes their functions through mutant proteomics.

Phase-separating pyrenoid proteins form complexes in the dilute phase

The paper demonstrates the existence of protein complexes in the dilute phase of phase-separating systems using an algal pyrenoid reconstitution system and fluorescence correlation spectroscopy.

Identification of green lineage osmotic stress pathways

This study identifies conserved osmotic stress pathways in green algae and plants using transcriptomics and functional genomics, revealing a novel actin remodeling mechanism.

Diffusion barriers and adaptive carbon uptake strategies enhance the modeled performance of the algal CO2-concentrating mechanism

The paper develops a chloroplast-scale reaction-diffusion model to analyze the algal CO2-concentrating mechanism (CCM), showing that diffusion barriers and adaptive carbon uptake strategies enhance its performance and efficiency.

Arabidopsis bZIP11 is a susceptibility factor during Pseudomonas syringae infection

This study identifies bZIP11 as a host transcription factor that promotes Pseudomonas syringae growth by regulating nutrient transporter expression in Arabidopsis.

Assembly of the algal CO2-fixing organelle, the pyrenoid, is guided by a Rubisco-binding motif

The paper identifies a Rubisco-binding motif that targets proteins to the pyrenoid and maintains its three sub-compartments.

Co-expressed subunits of dual genetic origin define a conserved supercomplex mediating essential protein import into chloroplasts

The paper identifies a conserved TicToc supercomplex in chloroplast protein import across species, showing coordinated gene expression and essential functional roles.
