Large-scale single-cell profiling of stem cells uncovers redundant regulators of shoot development and yield trait variation

Authors: Xu, X., Passalacqua, M., Rice, B., Demesa-Arevalo, E., Kojima, M., Takebayashi, Y., Harris, B., Sakakibara, H., Gallavotti, A., Gillis, J., Jackson, D.

AI Summary

The study finely dissected shoot stem cell–enriched tissues from maize and Arabidopsis thaliana and optimized single‑cell RNA‑seq protocols to reliably capture CLAVATA3 and WUSCHEL‑expressing cells. Cross‑species comparison and functional validation, including spatial transcriptomics and mutant analyses, revealed conserved ribosome‑associated RNA‑binding proteins and sugar‑kinase families as key regulators linked to shoot development and yield traits.

A drought stress-responsive metabolite malate modulates stomatal responses through G-protein-dependent pathway in grapevine and Arabidopsis

AI Summary

The study examined how tricarboxylic acid (TCA) cycle metabolites influence drought tolerance in grapevine and Arabidopsis, finding that malate uniquely triggers stomatal closure via elevations in cytosolic Ca2+ and activation of the SLAC1 anion channel. G-proteins were shown to be essential for malate‑mediated signaling, linking metabolic changes to drought response through a second‑messenger cascade.
