Update: Toward a data infrastructure for the Plant Cell Atlas (Plant Physiol)

The ability to analyze the information contained within a single cell, for example through single-cell RNA sequening (scRNA-seq) presents exciting possibilities to biologists. Building on this and similar technologies, the Plant Cell Atlas (PCA) (www.plantcellatlas.org/) has the goal of creating an information…

Arabidopsis latent virus 1, a comovirus widely spread in Arabidopsis thaliana collections (New Phytol)

Arabidopsis thaliana has been established as a versatile and important model plant species, with abundant genetic and genomic resources. Through RNA sequencing, Verhoeven et al. identified an unexpected and previously unnoticed latent comovirus (the name “como” derives from cowpea mosaic virus) lurking…

Robust transcriptional indicators of immune cell death revealed by spatio-temporal transcriptome analyses (Mol Plant)

Many plants trigger a form of cell death, known as the hypersensitive response (HR), immediately upon pathogen recognition. To minimize damage to the plant, this cell death must be highly localized to the site of attack, while more distal cells survive and activate other immune responses. However, the…

Live Plant Cell Tracking: A Fiji plugin to analyze cell proliferation dynamics and understand morphogenesis (Plant Physiol.)

Live Plant Cell Tracking: A Fiji plugin to analyze cell proliferation dynamics and understand morphogenesis Morphogenesis in plants occurs in 3D space over time, referred to as 4D. Recent advances in high-resolution microscopy imaging and computational pipelines have helped to better understand…

Review: 3D electron microscopy for imaging organelles in plants and algae (Plant Physiol)

Have you noticed that the quality and resolution of cell images has been getting better and better? Weiner et al. review the recent advances in 3D electron microscopy (EM) technologies that have provided these strikingly beautiful and informative images. Like “classic” transmission EM, EM tomography…

Review: Illuminating the hidden world of calcium ions in plants with a universe of indicators (Plant Physiol)

Calcium ions (Ca2+) are ubiquitous and essential signals, with a very steep concentration gradient from outside to inside the cell. Numerous studies from across the kingdoms have demonstrated that transient Ca2+ fluxes convey information of many types. Here, Grenzi et al. provide an Update on the tools…

SeedQuant: A deep learning-based tool for assessing stimulant and inhibitor activity on root parasitic seeds (Plant Physiol.)

Parasitic plants can completely wipe out a farmer’s harvest. The seeds can lie dormant in soil until they perceive signals from potential host plants, which stimulate germination. Therefore, germination stimulants applied to fields before the crops are planted can cause the parasitic seeds to germinate…

A biosensor for the direct visualization of auxin (Nature)

Auxin is an omnipresent, tryptophan-derived phytohormone that plays roles in innumerable physiological processes, so it is imperative to understand its distribution. Currently the best tools to do so employ the use of indirect sensors, such as the synthetic auxin-responsive promoter DR5. While invaluable,…
