Quan et al. show that warming-induced changes in plant community height in a cold, high-elevation region enhance ecosystem carbon sequestration, emphasizing the importance of plant traits in shaping the carbon cycle under climate change.
The authors integrate spatial (Stereo-seq) and single-cell transcriptomes of the developing maize ear to produce an atlas of maize ear cells and their developmental trajectories. They also identify a pair of transcription factors involved in inflorescence development.
Wang and colleagues report a two-dimensional root carbon trait space coupled with the root economics space, offering molecular insights into the great diversity of root form and function.
Abiotic stresses challenge plant growth. In response, plants often rapidly accumulate proline. This study reveals the filament structures of plant P5CS, the key enzyme in proline synthesis, elucidating a unique mechanism for its efficient catalysis.
This study shows that optimizing soybean nodulation, rather than supernodulation, through editing improves N and C assimilation by balancing source–sink relationships. As a result, soybean yield and protein content are simultaneously increased in field conditions.
This study identifies PPKs as authentic protein kinases phosphorylating the far-red light photoreceptor phytochrome A and demonstrates that liquid–liquid phase separation of TZP promotes PPK-mediated phosphorylation of phytochrome A in far-red light.
Repeat expansions can induce gene silencing exemplified by growth defects in plants to genetic diseases in humans. This paper shows key roles for post-translational modifiers, histone readers and the polycomb repressive complex in this gene silencing.
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.
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.
The cryo-EM structure shows us how thousands of protein components self-assemble into Prochlorococcus α-carboxysome. The scaffolding protein CsoS2 crosslinks the icosahedral-like shell and internal RuBisCOs, and determines the size of α-carboxysome.
Using a combination of single-cell and spatial transcriptomic analysis, Serrano et al. uncover transcriptional dynamics during the establishment of arbuscular mycorrhizal symbiosis.
Wang et al. report the cryo-electron microscopy structures of rice K+ transporters HKT2;1 and HKT2;2/1. These structures reveal critical insights into their ion selectivity and transport mechanisms that will aid in the development of strategies to increase yields.
He et al. found that locally adapted maize varieties exert patterns of genetic control on their root and rhizosphere microbiomes that follow variation in their home environments, consistent with a role in tolerance to prevailing stress.
Photosystem I (PSI) is one of two large pigment–protein complexes responsible for converting solar energy into chemical energy. This study reveals the previously unknown major PSI assembly pathway in land plants.
An efficient method of cyto-swapping by haploid induction using a CENH3 mutation is reported in maize, to convert commercial germplasm to cytoplasmic male sterility for hybrid seed production.
Han et al. develop BoCENH3 mutants which trigger paternal haploid induction in Brassica oleracea. On the basis of this haploid inducer line, a workable system is proposed for transferring cytoplasmic male sterility to broccoli inbred lines.
The authors show that RALF22 has a dual role in cell wall assembly in root hairs: as a structural component organizing cell wall architecture and as a feedback signalling molecule that regulates this process depending on its interaction partners.
