In this Perspective, Finger and Möhring discuss the emergence of pesticide-free crop production systems in Europe in the context of real-world examples and highlight the barriers to adoption of this cropping strategy.

The plant DNA damage response ensures genomic stability by controlling interconnected networks of DNA repair and cell division proteins. Decoding these networks offers potential solutions to the challenges of climate-related stress and food security.

This study collected and analysed 3,517 de novo assemblies from 1,575 plant species sequenced since 2000, including 793 newly sequenced species in the past three years. A database named N3: plants, genomes, technologies was developed to accommodate the metadata associated with the sequenced genomes.

In global drylands, soils tend to be more fertile beneath tree, shrub and grass islands. Soil fertility was greater beneath taller and wider plants but was unaffected by either grazing pressure or the type of herbivore.

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.

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.

In this Perspective, Mascher et al. look back on 30 years of genetic and genomic research in cereal crops. Genome sequences have revealed common evolutionary patterns as well as differences between species and will support applications in breeding.

The ‘non-canonical’ type-B BZR/BES transcription factor, MpBZR3, has been shown to be a regulator of the development of female and male reproductive organs in the model bryophyte Marchantia polymorpha.

NARROW LEAF1 (NAL1) exerts a multifaceted influence on rice leaf morphology and yield. Recent crystal study proposed that histidine 233 (H233) is part of the catalytic triad. Here we report that H234 instead of H233 is a component of the catalytic triad alongside D291 and S385.
