WebJan 7, 2024 · Pericycle cells taking part in an oscillation maximum and later on maintaining a steady auxin response maximum are defined as lateral root founder cells. Shortly after, these cells repolarize, as reflected by polar nuclear migration, immediately followed by the first asymmetric cell division (i.e., lateral root initiation). WebJul 16, 2024 · Lateral root (LR) formation in Arabidopsis thaliana is initiated by asymmetric division of founder cells, followed by coordinated cell proliferation and differentiation for patterning new primordia.
