Using in situ cryo-electron tomography, researchers found a unique ‘arm’ domain on the small subunit of Chlamydomonas chlororibosomes. This discovery suggests that chlororibosome structure is more evo...

Transcription in chloroplasts depends on the Plastid-Encoded RNA polymerase (PEP), a bacterial-derived enzyme whose catalytic core remains encoded by the highly reduced genome inherited from the cyano...

To overcome the enzymatic limitations of Rubisco, algae operate CO2-concentrating mechanisms (CCMs) that deliver concentrated CO2 to Rubisco tightly packaged in a specialized microcompartment called a...
