Review: CLAVATA signaling in plant-environment interactions

CLAVATA 3/EMBRYO SURROUNDING REGION-related (CLE) peptides and CLAVATA type receptors have been well charecterized for their role in root and shoot apical meristem maintenance in Arabidopsis. CLE peptides are also referred to as “peptide hormones” for their role in contolling physiological and developmental…

Lateral root branching promoted by ammonia borane-dependent H2

Molecular hydrogen (H2) has been shown to have several cellular benefits, most notably serving as an antioxidant. Its effects in humans and plants have been primarily assayed using hydrogen-rich water (HRW, produced by bubbling H2 into water), but slower, more persistent release of H2 has been demonstrated…

Immature leaves are the dominant volatile-sensing organs of maize

It’s well established that damaged plant tissues emit volatile compounds that bolster defense responses in nearby plants, but how those neighbors sense these compounds has remained obscure. This new work by Wang et al. reveals some important clues. First, as the title indicates, immature leaves are…

Identification of a plant receptor required for cell-to-cell reactive oxygen signaling

Fichman et al. identify a key player linking reactive oxygen species and calcium signals (but not electric signals) during responses to light stress. https://doi.org/10.1093/plcell/koac241 Yosef Fichman and Ron Mittler Division of Plant Sciences and Technology, College of Agriculture Food and Natural…

Review: Plasma membrane-to-organelle communication in plant stress signaling (Curr. Opin. Plant Biol.)

The plasma membrane (PM) is a critical interface between the cell and its environment and serves crucial sensing and transducing roles. This timely review by Medina-Puche and Lozano-Durán updates exciting new developments in understanding communication between the PM and intracellular organelles, focusing…
