    How to make a moss

    Recent advances in DNA synthesis techniques have made possible the de novo synthesis of substantial genomes of organisms such as mycoplasma, bacteria and yeast. Synthesis of the genome of a multicellular organism remains out of reach, but the moss Physcomitrium patens could be the first.

    Generating gametangia

    Bryophytes, such as the model liverwort Marchantia polymorpha, develop sexual organs known as gametangia. The ‘non-canonical’ transcription factor MpBZR3 is involved in regulating both male and female structures, antheridia and archegonia respectively. Overexpression of MpBZR3 induces ectopic development of multiple gametangia.

    Symbiosis in time and space

    The symbiotic interaction of arbuscular mycorrhizal fungi with plant roots enables the mutual exchange of carbon for nutrients such as phosphate. The course of this highly dynamic relationship can be followed by a combination of single-cell and spatial transcriptomics.

    Spreading the load

    Centromeres affect epigenomic architecture and meiotic recombination. The Brazillian plant Rhynchospora breviuscula has holocentric chromosomes with multiple kinetochores along their length, rather than a single centromere. Here, chromosome synapsis dynamics is key to the broad-scale pattern of crossovers. The image shows anthers, pollen and meiocyte of R. breviuscula.

    Tending to fire

    Fire has been an ecological driving force on Earth as long as there have been plants to burn. But human activity has altered fire regimes in unprecedented ways, with profound global consequences for carbon storage, ecosystem services and biodiversity.

    Passing on protection

    Developing embryos are supplied with maternally produced compounds, including glucosinolate defence compounds. To cross the four intervening cellular barriers requires plasma membrane-located exporters (such as UMAMIT29, labelled in green) and importers in maternal and embryonic tissues.
