Simple method for transformation and gene editing in medicinal plants

Gene-editing technologies have ushered in a significant advancement in plant genetics research and molecular breeding.However,a critical challenge hindering the widespread adoption of these technologies is the efficient delivery of gene-editing tools.The predominant methods for introducing these tools into plants typically involve Agrobacterium tumefaciens-mediated transformation or particle bombardment(Mao et al.,2019).Unfortunately,these traditional gene delivery methods require delicate and timeconsuming tissue culture procedures and show limited success,especially in medicinal and other less studied plants.A recent breakthrough is the development of the Cut-Dip-Budding(CDB)gene delivery system.The CDB system is highly effective for plants with root-suckering capabilities.It allows the delivery of transgenes and gene-editing tools into plants through hairy root induction followed by shoot regeneration from transformed hairy roots,bypassing the need for tissue culture processes(Cao et al.,2023).
