Cell polarity plays a fundamental role across all eukaryotic organisms, serving as a critical mechanism to initiate developmental patterns and guide cell behaviors in physiological processes. In the context of plants, polarity orchestrates the morphogenesis of individual cells, including pollen tubes, root hairs, and leaf epidermal cells. Additionally, it governs the formation of multicellular structures such as early embryos, lateral roots, and axial patterns within shoots and leaves.
The processes of single-cell morphogenesis and organ formation exhibit distinct requirements. Single-cell morphogenesis typically relies on the Rho-of-plants (ROP) signaling pathway, which regulates cytoskeletal networks to induce localized cell expansion. In contrast, organ development necessitates the polar transport of the plant hormone auxin, coupled with auxin’s role in specifying cell fate through transcriptional regulation. Recent advancements have shed light on the intricate regulation of polarity signaling. Furthermore, researchers have uncovered intriguing crosstalk between membrane polarity, hormone signaling pathways, and cell fate determinants. These discoveries mark a new era in our understanding of plant cell polarity and morphogenesis.
Although progress has been made in understanding polarity and its impact on plant morphogenesis, the complexity of polarity signaling remains a challenge. This Research Topic aims to explore how polarity regulates plant development, physiology, and morphogenesis in a broad context. By studying diverse plant species and cell types and employing methodologies such as genetics, advanced live-cell imaging, reconstitution, biochemical analysis, and mathematical modeling, it is possible to help establish advanced models in polarity-mediated morphogenesis and physiology in plants.
