If you work with grasses, you are probably familiar with the scutellum –the shield-like cotyledon typical of seeds from these plants. This structure has a renowned role in transferring nutrients to the growing embryo. However, Murphy and colleagues show us that not only does this structure look like…

Despite a large variation in leaf morphology, laminar leaf anatomy is largely conserved, comprising two developmentally distinct mesophyll tissues, the palisade and spongy mesophyll. Spongy mesophyll cells along with intercellular spaces form an interconnected network to maximize the surface area for…

Morphogenesis is a critical process in plants and animals that allows a cell, tissue, or organism to reach its final shape. In Arabidopsis thaliana, the formation of lateral root primordia (LRP) is an excellent example of organ morphogenesis that involves cell remodeling throughout differential growth…

In this seminal paper, Roszak et al. present a deeper understanding of the development of the protophloem cell lineage. The differentiation process from the phloem stem cell to the enucleated cell state spans approximately 19 cells. Using live imaging, FACS sorting and single-cell RNA sequencing, the…

Many biological processes are controlled by the circadian clock in plants, yet studies often don't report sampling timepoints, leaving much to be discovered about the plant circadian rhythm. Apelt et al. have utilised single cell RNA sequencing to examine almost 70,000 Arabidopsis cells from above and…

Flooding presents a dual threat to plants; not only is mitochondrial respiration supressed during the resulting hypoxic conditions, but once the floodwaters recede, the return to ambient oxygen levels triggers a cascade of harmful reaction oxygen species (ROS). One of the most well-studied responses…

Nesocodon mauritianus is about one out of 70 plant species that produce colored nectar. The nectar of Nesocodon starts off yellow in newly opened flowers and progresses to blood-red in color as the flowers mature. The authors showed that the red colored nectar is both visible and attractive to geckos,…

Do you know how many tree species are there? The global Forest Biodiversity Initiative (GFBI) database has annotated about 28,000 tree species, while some studies indicate there could be around 60,000. But why this difference? Many of the species are found in unapproachable areas. Additionally, human…
