    Plants require long-distance water transport to avoid desiccation. Here, via μCT and MRI of grapevine stem, Bouda et al. show evidence of pressure gradient heterogeneity and flow redirection from wide to narrow vessels that suggests narrow vessels contribute more to xylem sap flow than previously appreciated.

    Photosynthesis generates reactive oxygen species that can damage cells. Here, the authors show that unicellular predators of photosynthetic prey have shared responses to photosynthetic oxidative stress and these may also have been important for the evolution of endosymbiosis.

    Stem-cell-specific genes regulate processes such as maintenance, identity and/or division. Here, the authors show that in the Arabidopsis root TCX2, a gene expressed across different stem cell populations (a stem-cell-ubiquitous gene), controls division and identity by regulating stem-cell-type-specific networks.

    Unlike the other domesticated maize, sweet maize and popcorn retain tillering growth habit, but the underlying mechanism is unknown. Here, the authors identify a transcription factor tin1 that maintains outgrowth of tiller independent of tb1 and show its conservation in foxtail millet and rice.

    Chloroplasts are important for plant immunity against microbial pathogens. Here Xu et al. identify, in the wheat stripe rust fungus, a haustorium-specific protein that is translocated into chloroplasts and affects chloroplast function by interacting with a putative component of the plant cytochrome b6-f complex.

Here the authors show that rootward movement of shoot-synthesized G3P occurs in response to root-recognition of incompatible rhizobia and promotes exclusion of non-desirable bacteria in roots.

    In flowering plants, the CONSTANS (CO) and Nuclear Factor Y (NF-Y) transcription factors connect light perception to floral induction. Here Tokutsu et al. show that in the green alga Chlamydomonas, CO and NF-Y form an analogous complex that can prevent photodamage in response to excess light.

    Brassicaceae produce glucosinolates to protect against herbivory and pathogens. Here the authors show that auxin-sensitive Aux/IAA repressor proteins regulate aliphatic glucosinolate levels in Arabidopsis and this promotes stomatal closure via reactive oxygen species during drought stress.

    Stripe rust is a serious threat to wheat production. Here, the authors reveal that the resistance gene, only present in the wheat progenitor Aegilops tauschii and its derived synthetic wheat, encodes a nucleotide oligomerization domain-like receptor and confers resistance in common wheat and barley.

    Tropane alkaloids are medicinally significant plant metabolites generated by an unusual condensation of ornithine-derived and malonyl-CoA precursors. Here, Huang et al. show that pyrrolidine ketide synthase catalyzes a single round of condensation, which is followed by a non-enzymatic Mannich-like condensation.

    The role of Blue Carbon in climate change mitigation and adaptation has now reached international prominence. Here the authors identified the top-ten unresolved questions in the field and find that most questions relate to the precise role blue carbon can play in mitigating climate change and the most effective management actions in maximising this.

    Plant hypoxia responses are controlled by oxygen and nitric oxide (NO)-dependent proteolysis of ERFVII transcription factors. Here Hartman et al. show that passive ethylene entrapment during root submergence enhances NO-scavenger PHYTOGLOBIN1, ERFVII stability and promotes subsequent hypoxia tolerance.

    In plants, phytochrome B senses light cues indicative of neighbouring competitors leading to accelerated flowering. Here the authors show that PHYTOCHROME INTERACTING FACTORs 4, 5 and 7 (PIF4, PIF5 and PIF7) mediate neighbor proximity-induced flowering acting downstream of phyB to promote expression of FT and TSF.

    RNA polymerase V transcription in plants, which is needed DNA methylation and transcriptional silencing, requires components of the DDR complex. Here the authors show that all components of the DDR complex co-localize with Pol V and report the cryoEM structures of two complexes associated with Pol V recruitment.
