Structure of intact α-carboxysome specifies role of CsoS2 in shell assembly

Nature Plants, Published online: 11 April 2024; doi:10.1038/s41477-024-01667-2

The carbon fixation machinery α-carboxysome of the marine cyanobacterium Prochlorococcus is composed of an icosahedral-like proteinaceous shell that encapsulates the enzymes RuBisCO and carbonic anhydrase. Our cryo-EM structure reveals how thousands of protein components self-assemble into the α-carboxysome and characterizes the multivalent interactions by which the scaffolding protein CsoS2 crosslinks the shell with internal RuBisCO molecules.

An old mission revealed for BZRs

BZR/BES transcription factors are widely recognized as mediators of brassinosteroid (BR)-responsive gene expression in seed plants, but details of how they act in species that lack BR perception are unclear. A study now uncovers an ancient mission of a BZR/BES transcription factor in sexual organ development in the liverwort Marchantia polymorpha.

Improving rice nitrogen-use efficiency by modulating a novel monouniquitination machinery for optimal root plasticity response to nitrogen

Nature Plants, Published online: 05 October 2023; doi:10.1038/s41477-023-01533-7

This study reveals the role played by the RNR10-DNR1-auxin module in modulating rice root system architecture and nitrogen uptake, making it a promising target for enhancing nitrogen-use efficiency and grain yield for future sustainable agriculture.
