Root formation under natural conditions is plastic in response to multiple signals. Recent studies suggested that theWUSCHEL‐RELATED HOMEOBOX11(WOX11)‐mediated adventitious root formation pathway can occur in the primary root (PR) inArabidopsis thaliana, resulting in the production of a specific type of lateral roots (LRs) in response to wounding or environmental signals. This process differs from the previously characterized process for LR development, which does not requireWOX11. TheWOX11‐mediated PR‐derived roots can be considered like LRs that exhibit an ‘adventitious’ feature. Therefore, we consider these roots to be adventitious lateral roots (adLRs). The identification ofWOX11‐mediated adLRs implies that studying the formation of roots in response to wounding and environmental signals is important for characterizing the plasticity of the root system architecture.
