Intensive Spatiotemporal Characterization of the Tire Wear Toxin 6PPD Quinone in Urban Waters.

6PPDQ is a tire-derived contaminant toxic to coho salmon (LC = 41-95 ng/L) found widely distributed in urban environments. Most monitoring efforts have relied on relatively few discrete samples collected at select locations across rain events. Early work has revealed that 6PPDQ concentrations vary widely over time and space, raising questions about when and where to collect samples.

Catalytically inactive subgroup VIII receptor-like cytoplasmic kinases regulate the immune-triggered oxidative burst in Arabidopsis thaliana.

Protein kinases are key components of multiple cell signaling pathways. Several receptor-like cytoplasmic kinases (RLCKs) have demonstrated roles in immune and developmental signaling across various plant species, making them of interest in the study of phosphorylation-based signal relay. Here, we present our investigation of a subgroup of RLCKs in Arabidopsis thaliana.

A quick guide to the calcium-dependent protein kinase family in .

, commonly known as rapeseed or canola, is an economically valuable oilseed crop grown throughout Canada that currently faces several challenges due to industrial farming practices as well as a changing climate. Calcium-dependent protein kinases (CDPKs) are key regulators of stress signaling in multiple plant species. CDPKs sense changes in cellular calcium levels via a calmodulin-like domain and are able to respond to these changes via their protein kinase domain.

Subfamily C7 Raf-like kinases MRK1, RAF26, and RAF39 regulate immune homeostasis and stomatal opening in Arabidopsis thaliana.

The calcium-dependent protein kinase CPK28 regulates several stress pathways in multiple plant species. Here, we aimed to discover CPK28-associated proteins in Arabidopsis thaliana. We used affinity-based proteomics and identified several potential CPK28 binding partners, including the C7 Raf-like kinases MRK1, RAF26, and RAF39.
