Abscisic acid signaling regulates primary plasmodesmata density for plant cell-to-cell communication
Abstract
Cell-to-cell communication is essential for multicellular organisms. Plasmodesmata (PD) are plant-specific nanopore structures pivotal for cell-to-cell communication and plant survival. However, how PD form and their structure, regulation, and evolution remain largely unknown. Here, we demonstrate that the exogenous supply of abscisic acid (ABA), a well-conserved phytohormone in land plants, reduces primary PD density in the moss Physcomitrium patens. This regulation requires all core components of the ABA signaling pathway. Furthermore, we reveal that ……
