Auxin is an extremely important plant hormone that must be precisely controlled. Auxin-like herbicides have been developed that are often more stable than the natural auxins, thus their application can damage the plant. Here, Schulz, Ung et al. investigated how these auxin herbicides move in plant tissues.…

A recent paper by Scheuring and colleagues investigates vacuole biogenesis in meristematic cells of Arabidopsis thaliana, challenging earlier models of vacuole formation. Vacuoles are crucial organelles responsible for various cellular functions, yet their formation has remained puzzling for quite some…

Have you ever wondered how cells distinguish between the diverse array of external signals traveling through similar pathways? To understand the intricacies of plant signaling mechanisms, Ma et al. used single endodermal cells of Arabidopsis roots as a model to compare two receptor pathways. One pathway…

In acidic soils, aluminum (Al) toxicity is a major problem that causes a dramatic arrest in root elongation. Aluminum tolerance can include the secretion of organic acids and the sequestration of Al in internal cellular compartments. Here, Dong et. al shed light on a new pathway that alleviates the inhibition…

Heterosis, the phenomenon where hybrid plants outperform their genetically distinct parents, is a cornerstone of modern agriculture. This review by Hochholdinger and Yu explores the molecular mechanisms behind heterosis. The review traces the history of heterosis, from its early discovery in tobacco…

Maintaining root growth is a major plant adaptation to water deficit, enabling continued access to soil water. In a recent review, Voothuluru et al. discuss the inherent complexity of root systems in regard to water stress. Different root types, including primary, seminal, and nodal roots, show varying…

The development of genetically modified (GM) crops aims to improve agricultural yields in the field. However, their incorporation into agricultural systems is complex, as regulations and acceptance vary globally. While some countries embrace GM crops with herbicide and insect resistance traits, others…

Cyanobacteria, although short-lived, are sensitive to photoperiodic time measurement just as in eukaryotes. Jabbur et al. discuss the discovery of photoperiodism in prokaryotic cyanobacteria, Synechococcus elongatus and their ability to anticipate seasonal changes through light and dark cycles similar…
