Bauer et al. characterize UGT76B1 as a metabolic suppressor of the Arabidopsis immune response. The Plant Cell (2021). https://doi.org/10.1093/plcell/koaa044 By Dereje W. Mekonnen1, Jürgen Zeier2, Anton R. Schäffner1 1Institute of Biochemical Plant Pathology, Department of Environmental Sciences,…

One of the great questions in plant science has been, “How do plants recognize friend from foe?” Like most great questions, this one benefits from a historical perspective. In their new review, Delaux and Schornack look at plant evolution through the lens of plant interactions with symbiotic and…

Three key factors affect a plant’s ability to fix carbon: enzymatic activity of Rubisco, stomatal conductance, and the journey from sub-stomatal cavity to Rubisco, also known as mesophyll conductance (gm). This latter is the focus of this new work by Clarke et al. They delightfully compare this journey…

Plants have evolved well-coordinated crosstalk between different signaling pathways to respond and adapt to various environmental stresses. Brassinosteriods (BRs) and Target of Rapamycin Complex (TORC) have multiple roles, through transcription, translation and autophagy, to control the balance between…

Gibberellin (GA) controls multiple developmental processes throughout the plant life cycle, from seed germination to flowering. In Arabidopsis, GA also regulates division of meristematic cells at the tip of the root and cell elongation in the growing zone. Despite its importance, little is known about…

The osmotic state of a cell is affected by internal (metabolite content) and external (water availability) factors. Recent work by Cuevas-Velazquez and colleagues describes the design of a FRET-based biosensor that allows dynamic monitoring of osmotic stress in living cells. They exploited features of…

Seed germination, a critical life stage in a plant's life cycle, can be affected by internal seed morphology. In this exciting research, Vandelook and colleagues investigated the evolution of embryo and nutritive tissue characteristics and their relationship with the germination traits of 84 species…

Review: Plant evolution driven by interactions with symbiotic and pathogenic microbes One of the great questions in plant science has been, “How do plants recognize friend from foe?” Like most great questions, this one benefits from a historical perspective. In their new review, Delaux and Schornack…
