  • Intracellular calcium waves are key signalling elements during the fertilization process of animals, involved in egg activation. Here the authors image calcium oscillations during the fertilization process in flowering plants, revealing specific signatures involved in the success of this process.

  • Vessel elements arise from cambium stem cells and support plant growth by supplying water and nutrients. This study reveals that strigolactone signalling inhibits vessel formation in response to drought, affecting transpiration and drought resistance.

  • During cell division, Soronin antagonises WAPL to prevent premature loss of sister chromatid cohesion. Here the authors show that, despite a lack of sequence similarity, the Arabidopsis SWI1 protein functions as a novel Soronin-like WAPL antagonist, suggesting convergent evolution with animals.

  • Septins are a family of heteropolymerizing GTP/GDP-binding proteins and are implicated in neuritogenesis in nematodes. Ageta-Ishihara et al.show that septins also facilitate this process in the developing mouse brain as scaffolds that coordinate HDAC6-mediated deacetylation of microtubules.

  • In this study, Higashiyama and colleagues examine pollen tube guidance in Torenia fournieri and identify the secreted guidance factors. These are cysteine-rich polypeptides belonging to the subgroup of defensin-like proteins (designated as LUREs), which are predominantly expressed in synergid cells and are required for pollen tube guidance.
