Arabidopsis thaliana RPL13aC affects root system architecture through shoot potassium accumulation.

Plant root system architecture shows complex patterns adapting to different nutritional conditions. In Arabidopsis thaliana, root slanting is a behaviour that is observed when plants are grown on a solid agar plate vertically. However, the regulatory mechanisms of root slanting in response to nutrient conditions are not fully understood.

Root-specific CLE3 expression is required for WRKY33 activation in Arabidopsis shoots.

This study focused on the role of CLE1-7 peptides as defense mediators, and showed that root-expressed CLE3 functions as a systemic signal to regulate defense-related gene expression in shoots. In the natural environment, plants employ diverse signaling molecules including peptides to defend themselves against various pathogen attacks. In this study, we investigated whether CLAVATA3/EMBRYO SURROUNDING REGION-RELATED (CLE) genes (CLE1-7) respond to biotic stimuli.

CLE2 regulates light-dependent carbohydrate metabolism in Arabidopsis shoots.

This study focused on the role of CLE1-CLE7 peptides as environmental mediators and indicated that root-induced CLE2 functions systemically in light-dependent carbohydrate metabolism in shoots. Plants sense environmental stimuli and convert them into cellular signals, which are transmitted to distinct cells and tissues to induce adequate responses. Plant hormones and small secretory peptides often function as environmental stress mediators.
