Plant Physiology Focus Issue Webinar: Plant Cell Polarity Sept 25, 2023

Plant Physiology Webinar: Plant Cell Polarity Celebrating the September 2023 Focus Issue on Plant Cell Polarity Recorded Monday, September 25, 2023 About This Webinar Plant cell polarity 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 […]

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: although 97% of red algal species are marine, one lives in sloth hairs, and nori (sushi seaweed) […]

Review: How plant roots respond to waterlogging

As the hottest year on record, 2023 has truly been a global annus horribilis during which humans, other animals, and domesticated and wild plants have faced unprecedented environmental challenges. In the past month alone, torrential rainfalls have wreaked havoc in Asia, the Middle East, and many parts of Africa, Europe, and the Americas. Frightenedly, disruptive […]

Plant Physiology Focus Issue: Plant Cell Polarity

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, guiding the direction of cell expansion, and determining the spatial […]

The Plant Cell Focus Issue: Biomolecular Condensates

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 organelles (e.g., nucleolus, pyrenoid) to small, transient functional condensates, some of which are only recently […]

Immature leaves are the dominant volatile-sensing organs of maize

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 much more responsive to damage-associated volatiles (the authors specifically […]

Water fluxes contribute to growth patterning in shoot meristems

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 fluxes, cell wall properties, cytoskeletal patterns, and more. In this new preprint […]

LysM-mediated signaling in Marchantia polymorpha and conservation of PTI in land plants

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 plants, providing much-needed insights into their evolutionary origins and trajectories. Here, […]
