  • Vanilla flower

    To prevent, halt and reverse the degradation of ecosystems, the UN has declared the Decade on Ecosystem Restoration. Fallow-derived vanilla agroforestry can support the restoration of biodiversity in agricultural lands and provide a profitable alternative to further expansion into old-growth forest.

  • A typical spiny plant Gleditsia microphylla (Fabaceae) native in Asia

    Numerous well-preserved Eocene (~39 Ma) plant spine fossils discovered in the central Tibetan Plateau, combined with molecular phylogenetic reconstruction, point to a rapid diversification of spiny plants in Eurasia around that time.

  • Plants growing through black plastic.

    By constructing experimental plant neighborhoods and performing a subsequent microbiome transplant experiment, Meyer et al. (2022) have provided evidence that a plant's neighbors can play a decisive role in the formation of its microbiome.

  • At a time when food security is being threatened by climate change and population growth, regulatory systems must be designed to encourage innovation through all available technological means. Proposed changes to the concept of essential derivation will classify all mono-parental varieties as essentially derived, threatening the use of new breeding technologies to deliver crop improvement.

  • A major bottleneck in plant breeding is the establishment or breakage of genetic linkages by random, naturally occurring meiotic recombination. This problem can be overcome by CRISPR–Cas-mediated chromosome engineering. By inverting ~17 Mb of chromosome 2 of Arabidopsis thaliana, we almost completely suppressed genetic crossovers in nearly the entire chromosome.

    Research Briefing
  • Any long-term solution to the projected decline in phosphate supply must involve improving phosphorus use efficiency in crop plants.

    Editorial
  • Cooperation between nitrogen assimilation and photosynthesis is central for plant growth and development in adaption to changing environmental conditions. This work reveals that the plant energy sensor SnRK1 represses nitrate signalling by phosphorylating NODULE INCEPTION PROTEIN-LIKE PROTEIN (NLP7) to promote its degradation in response to carbon deficiency or nitrate depletion.

    Research Briefing
  • Crop production depends to a very large extent on phosphorus fertilization, yet the sustainability of this practice is limited by the predicted exhaustion of phosphorus resources. A new molecular pathway regulating phosphorus accumulation in plants has been identified, with PHO1 found to play a pivotal role in mediating it.

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.
