- Plasmodesmata-localized proteins and ROS orchestrate light-induced rapid systemic signaling in Arabidopsis
Systemic propagation of ROS waves in response to local light stress in Arabidopsis requires plasmodesmata proteins.
- Control of ribosomal protein synthesis by the Microprocessor complex
The Microprocessor complex resolves R-loops to enable ribosome biogenesis during nutrient-replete conditions.

About The Cover
Online Cover This week features a Research Article that demonstrates that systemic ROS signaling in response to localized light stress in Arabidopsis thaliana enhances stress tolerance throughout the plant and requires proteins that mediate the rapid enlargement of plasmodesmata pores. The image is an electron micrograph showing adjacent plant cells connected by an M-shaped plasmodesma, which crosses the cell walls and connects the cytoplasm of the two cells.
