The September issue of Plant Physiology has a focus on plant cell polarity, which plays a pivotal role in the fundamental processes that dictate plant growth, development, and adaptation. By establishing distinct regions within cells, plant cell polarity is crucial for regulating asymmetric cell divisions,…

The September issue of The Plant Cell includes a focus on biomolecular condensates. Although the term “biomolecular condensates” is relatively new, it actually reflects a convergence and synthesis of several distinct threads of research. Biomolecular condensates span from “classic” membraneless…

It’s well established that damaged plant tissues emit volatile compounds that bolster defense responses in nearby plants, but how those neighbors sense these compounds has remained obscure. This new work by Wang et al. reveals some important clues. First, as the title indicates, immature leaves are…

Common buckwheat (Fagopyrum esculentum) is a self-incompatible orphan crop which is gaining interest as it can be grown worldwide and grows well in low fertility soil. However, there are limited genomic resources available for common buckwheat. Here Fawcett et al. combined Illumnia short-read data with…

The shoot apical meristem (SAM) is a wonderous thing. How this tiny clump of cells generates the entire above-ground organ system regularly, predictably, and dynamically is a question that has been investigated for decades, with models incorporating cascades regulatory genes, diffusible peptides, hormone…

Marchantia polymorpha, the common (but adorable) liverwort, has earned its spot in the ranks of very important plant model systems, joining Physcomitrium patens as representatives of the bryophyte clade. Many systems first characterized in Arabidopsis and other angiosperms are now being studied in these…

Review: Red macroalgae in the genomic era I highly recommend this excellent and accessible article by Borg et al. that provides an overview of the red macroalgae, which “may have been the first eukaryotic lineage to have evolved complex multicellularity”. It’s full of fascinating information:…

Bournonville et al. explore which factors control ascorbic acid biosynthesis in plants and its accumulation in fruits. https://doi.org/10.1093/plcell/koad108 Céline Bournonville, Bayer SAS, 1050 Route de Pardies, 40300 Peyrehorade, France Kentaro Mori, Université Bordeaux, INRAE, UMR Biologie…
