  • Maize plants in field

    Ancient DNA studies on Indigenous domesticates like maize increasingly provide new insights into the lives and agricultural practices of the Americas' pioneering farmers, complementing ancient genomics of Indigenous human remains.

  • Mixed seedlings in soil

    The great scientific value of grassland plant diversity experiments such as the Jena Experiment or Cedar Creek is intriguing. Major discoveries about the role of biodiversity in controlling ecosystem functioning and services have been made in these experiments and consensus was made on the positive effect of plant species diversity on primary productivity.

  • Forest trees

    The growth of the various organs of trees obey allometric rules, which can be used to assess the carbon storage of forests, their ability to absorb CO2, and their response to climate change. But unlike mammals, fishes, birds, insects, and microbes, the difference between the weight of an individual sapling and a mature tree for woody plants has reached an astonishing degree.

  • Anthropogenic climate change is often portrayed as a consequence of industrialization powered by fossil fuel consumption. However, agriculture also plays a role in this complex system of causes and effects.

    Editorial
  • On 13 June 2021, the people of Switzerland voted on two popular initiatives that aimed to introduce stricter pesticide policies. Both initiatives were rejected, but the political and societal debate led to large changes in governmental and industry policies.

  • Light-induced ‘speckles’, or photobodies, have been long known in plants, but the mechanistic basis of their formation along with their cellular function have remained a mystery. Answers to both questions have now been provided.

  • MicroRNAs are key mobile players in many developmental and stress response pathways within plants. The role of miRNAs has now been expanded to include functioning as exogenously applied effectors and also plant-to-plant communicators of gene regulatory programs.

  • By quantifying over 100 Cannabis samples for terpene and cannabinoid content and genotyping them for over 100,000 single nucleotide polymorphisms, this study finds that Cannabis labelling is associated with genetic variants in terpene synthase genes.

  • Plants have developed defences against herbivores, but with multiple threats at different times, those defences may be compromised. This experiment finds that plants adapt over time to anticipate prevalent herbivores and common patterns of attack.

  • Cryptochromes (CRYs) perform various functions in both plants and animals, including photoperception and circadian regulation. Now it is shown in Arabidopsis that blue light induces liquid–liquid phase separation of CRY2, co-condensing the interacting m6A writer and altering epitranscriptome with respect to the circadian clock.

  • This study shows that miRNAs produced by plants act as signalling molecules that affect gene expression in nearby plants. This RNAi induced by exogenous miRNAs enables communication between plants and requires the production of secondary siRNAs.

Sustainable solutions to end hunger

Sustainable solutions to end hunger

Effective agricultural interventions could aid efforts to find sustainable solutions for ending hunger. In this collection, we present evidence-based recommendations from the Ceres2030 team on where to prioritize spending on interventions to achieve zero hunger by 2030.
