  abstract = {{L}ateral root formation is an important determinant of root system architecture. {I}n {A}rabidopsis, lateral roots originate from pericycle cells, which undergo a program of morphogenesis to generate a new lateral root meristem. {D}espite its importance for root meristem organization, the onset of quiescent center ({QC}) formation during lateral root morphogenesis remains unclear. {H}ere, we used live 3{D} confocal imaging to monitor cell organization and identity acquisition during lateral root development. {O}ur dynamic observations revealed an early morphogenesis phase and a late meristem formation phase as proposed in the bi-phasic growth model. {E}stablishment of lateral root {QC}s coincided with this developmental phase transition. {QC} precursor cells originated from the outer layer of stage {II} lateral root primordia, within which the {SCARECROW} ({SCR}) transcription factor was specifically expressed. {D}isrupting {SCR} function abolished periclinal divisions in this lateral root primordia cell layer and perturbed the formation of {QC} precursor cells. {W}e conclude that de novo {QC} establishment in lateral root primordia operates via {SCR}-mediated formative cell division and coincides with the developmental phase transition.},
