  • 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.

  • fungi on plates

    Complex microbial consortia inhabit plant roots and influence the health and development of their host. The development of experimental approaches with synthetic microbial communities (SynComs) disentangle the effects and functions of the root microbiota.

  • Organisms living at elevation are exposed to a constant state of hypoxia compared to those at low altitude. A recent study1 has shown that flowering plants acclimatize to high altitude through natural variation in molecular oxygen (O2) sensing, with high-altitude populations exhibiting increased O2 sensitivity to balance physiological and metabolic outputs. This finding demonstrates convergent mechanisms for altitude adaptation across eukaryotic kingdoms despite differences in the hypoxia-signalling pathways of plants and animals.

  • Arabidopsis embryonic root development involves the formation of distinct cell types and tissues in a tightly regulated and thereby highly predictable spatio-temporal manner. A crosstalk between maternal and embryonic genes orchestrates division orientation and fate specification to control root development.

  • An embryo-maternal communication orchestrates cell division orientation and cell fate specification during embryonic root development. This signalling is mediated by the WIP gene family members expressed embryonically and maternally.

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.
