Conservation bias

Thirty per cent of the world’s plant species are conserved in botanic gardens, over forty per cent of species known to be threatened. However, there are geographic disparities. Temperate species are more likely to be held by a botanic garden than tropical species, reflecting the high cost of maintaining tropical conditions.

    Cities need green spaces to maintain the well-being of their citizens. But is the realization of their value making them more private luxury than public commons?

    The European infrastructures EMPHASIS and AnaEE aim to collaborate in bringing innovative solutions for a sustainable intensification of agriculture. By integrating the study of plant phenomics and agricultural ecology they hope to foster the development of novel scientific concepts, sensors and integrated models.

    Temperature increases are associated with decreases in rainfall and ensuing crop yields. A recent study estimates that such warming over the last 30 years is responsible for 59,300 extra suicides in India, and proposes a new perspective to contextualize the linked effects of global warming in affected agricultural communities.

    Gibberellins (GAs) control key growth and developmental processes in plants. Real-time monitoring of GA concentrations in living tissues is critical for understanding the actions of this hormone class. A first-generation optogenetic GA-nano-indicator now illuminates the effects of GA levels on cell length and light signalling.

    A mechanism by which plants detect and respond to oxygen starvation has been known for some years. Three recent papers suggest that we haven’t been seeing the full picture.

    A global analysis of translation efficiency and RNA accumulation revealed that microRNAs in the unicellular green alga Chlamydomonas regulate target gene expression via RNA destabilization and translational repression like land plants and metazoans, yet in a different way.

    Plastids are integrated into the cellular metabolism by several metabolite and ion transporters. The first crystal structure of one of these transporters, a member of the plastid phosphate transporter family, unravels a rocker-switch transport mode and serves as lead structure for other plastidial and endomembrane system transporters.

    Programmed cell death is essential but differently regulated in animals and plants. In this Perspective, the features of plant apoptotic-like cell death are reassessed to highlight the similarities between animal and plant programmed cell death.

    Gibberellin (GA) is a plant hormone that plays an irreplaceable role in regulating growth and development. Now, the first fluorescent GA biosensor has been developed to visualize GA distributions at cellular resolution in Arabidopsis.

    It remains unknown how the central metabolite acetyl-CoA affects histone acetylation in plants. Chen et al. now show that cytosolic acetyl-CoA promotes histone acetylation predominantly at H3K27 in Arabidopsis.

    The first crystal structures of TPT, a membrane transporter that exports the Calvin cycle intermediates from chloroplasts and plays fundamental roles in nearly all photosynthetic eukaryotes, have now been resolved in complex with different substrates.
