“…Similar outcomes were reported by (Domokos-Szabolcsy et al, 2012) where SeNPs boosted tobacco root development at the optimal range. It was justi ed that lower concentrations of SeNPs elicit the induction of roots, cause less phytotoxicity, and have a tremendous effect on the morphological and microstructure pro ling of the root(Hajiboland et al, 2020;Han et al, 2013). Consistent with our outcomes, the application of SeNPs stimulated root development in Nicotiana tabacum by prompting Auxin fabrications(Jia et al, 2018).…”

The commercial-scale production of Caralluma tuberculata faces significant challenges due to lower seed viability and sluggish rate of root growth in natural conditions. To overcome these obstacles, using phyto mediated selenium nanomaterials as an invitro rooting agent in plant invitro cultures is a promising approach to facilitate rapid propagation and enhance the production of valuable therapeutic compounds. This study aimed to investigate the impact of phytosynthesized selenium nanoparticles (SeNPs) on the morphological growth attributes, physiological status, and secondary metabolite fabrication in in vitro micro propagated Caralluma tuberculata. The results demonstrated that a lower dose of SeNPs (100 µg/L) along with Plant growth regulators (IBA: 1 mg/L) had an affirmative effect on growth parameters and promoted earliest root initiation (4.6±0.98 days), highest root frequency (68.21±5.12%), number of roots (6.3±1.8), maximum fresh weight (710±6.01 mg) and dry weight (549.89±6.77 mg). However, higher levels of SeNPs (200 and 400 µg/L) in the growth media proved detrimental to growth and development. Further, stressed caused by SeNPs at 100 ug/L along with PGRs (IBA: 1 mg/L) produced higher level of total chlorophyll contents (32.66± 4.36 ug/ml), while cultures exposed to 200 ug/L SeNPs alone exhibited maximum amount of Proline contents (10.5± 1.32 ug/ml). Interestingly, exposure to 400 µg/L SeNPs induced a stress response in the cultures, leading to increased levels of total phenolic content, total flavonoid content, and antioxidant activity (3.4 ± 0.052, 1.8 ± 0.034 and mg/g dry weight: DW and 82 ± 4.8%). Furthermore, the combination of 100 µg/L SeNPs and plant growth regulators (1 mg/L IBA) led to accelerated enzymatic antioxidant activities, including superoxide dismutase (SOD = 4.4 ± 0.067 U/mg), peroxidase dismutase (POD = 3.3 ± 0.043 U/mg), catalase (CAT = 2.8 ± 0.048 U/mg), and ascorbate peroxidase (APx = 1.6 ± 0.082 U/mg). This is the first report that highlights the efficacy of SeNPs in culture media and presents a promising approach for the commercial propagation of C. tuberculata with strong antioxidant defense system in vitro.
