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…

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 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…

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…

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…

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…

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,…
