Lateral root
Videos
Lateral roots, emerging from the pericycle, extend horizontally from the primary root and over time make up the iconic branching pattern of root systems. They contribute to anchoring the plant securel
Primordium
…Though primordia are typically only found in new flower and leaf growth, root primordia in plants can also be found, but are typically referred to as lateral root primordium or adventitious roots. The process of lateral root primordium initiation has been studied in Arabidopsis thaliana, though the process in…
