| Summary: | The rhizome of <i>Atractylodes lancea</i> (Thunb.) DC. is a traditional Chinese medicine used extensively owing to its antimicrobial properties. It is utilized to treat nyctalopia and problems related to the gastrointestinal tract. However, its yield is limited because of its endangered status, long growth period, and restricted reproductive ability. Ancillary approaches have not been established to ensure sustainable resource utilization by applying efficient plant regeneration technologies and producing bioactive metabolites via genome editing. This study reports the effects of explants, hormones, and culture conditions on embryogenic callus induction, plant regeneration, adventitious and hairy root cultivation, and essential oil production. Embryogenic calli were successfully induced in MS and 2.0 mg/L 2,4-D and 1.0 mg/L NAA and 1/2MS medium supplemented with 4.0 mg/L 6-BA and 0.4 mg/L NAA, which were optimal for callus differentiation. Maximum proliferation (12-fold) of cluster buds was observed with a select combination of hormones [NAA (0.2 mg/L) and 6-BA (2.0 mg/L)]. “Efficient plant regeneration and bioactive metabolite production” can provide technical support for the protection and sustainable utilization of <i>A. lancea</i> germplasm resources in terms of resource preservation and new variety breeding, natural product production, and industrial breeding of medicinal plants. |
