Plants are sessile and must sense and adapt to environmental stresses, including mechanical forces from wind or physical contact. Mechanosensitive genes, such as those in the Mechanosensitive channel of Small conductance-Like (MSL) family, prevent cell rupture by acting as osmotic safety valves under stressful conditions. In this study, Suda et al. investigated the role of […]
Root angle is the direction and spatial orientation of roots in relation to gravity, which aids nutrient uptake and anchorage. Root angle is shaped by gravity perception, asymmetric auxin distribution, and differential growth across root zones. While auxin response factors (ARFs) are known to regulate this process, their downstream targets remain unclear. Song et al. […]
Mitochondria move within cells to support bioenergetic function and enable sharing of content, including mitochondrial DNA (mtDNA). Since not all plant mitochondria carry a full set of, or any mtDNA, sharing may allow genetic material to spread across the population. This creates a connected network of mitochondria that interact and homogenize their contents. However, the […]
Root cells are organized into concentric layers that facilitate the movement of water and nutrients. Among these, the endodermis overlays the root vasculature, allowing it to play a major role in selective uptake. To perform this function, endodermal cells undergo two distinct stages of differentiation. The first stage involves the formation of the Casparian strip […]
Cells are as small as life gets, but can be much larger than they appear if given room for expansion. This is possible with expansion microscopy, a technique that enables three dimensional cell imaging by physically expanding cellular components for visualization. Although expansion microscopy has been used in several eukaryotic systems, it is only recently […]
Field-based technologies are essential for understanding plant mechanical behavior in field-relevant contexts. This behavior can be elastic, with temporary deformation measured as stiffness, or plastic, with permanent deformation measured as strength. While field-based technologies exist for addressing questions regarding stalk stiffness, stalk strength, and root system strength, root system stiffness has not been fully understood […]
