Apocarotenoid signaling regulates meristem activity and shapes shoot and root lateral organ formation in Arabidopsis

This study shows that ACS1, an apocarotenoid signal, regulates meristem activity and lateral organ formation in Arabidopsis by modulating gene expression and developmental processes.

ATG8i Autophagy activation is mediated by cytosolic Ca2+ under osmotic stress in Arabidopsis thaliana

This study shows osmotic stress and cytosolic Ca2+ regulate ATG8i autophagosome accumulation in Arabidopsis thaliana, with ATG8i involved in ER-phagy under stress.

Interplay between positive and negative regulation by B3-type transcription factors is critical for the accurate expression of the ABA INSENSITIVE 4 gene.

The paper identifies a regulatory circuit involving LEC2, ABI3, and HSI/VAL proteins that controls ABI4 gene expression through RY cis-acting motifs and chromatin structure in plants.
