Abstract Stevia (Stevia rebaudiana Bertoni) contains sweet compound widely used as natural sweetener, steviol glycoside (SG). SG is a diterpenoid secondary metabolite synthesized from ent-kaurenoic acid, the same precursor of Gibberellin (GA). Therefore, in this study, a GA inhibitor, Daminozide (0, 10, 20 ppm) was used to block ent-kaurenoic acid conversion towards GA synthesis in attempt to increase SG content of stevia propagated in Temporary Immersion Bioreactor (TIB). Daminozide in 10 mg/L was observed to be the optimum concentration which increased biomass weight and SG content (stevioside and rebaudioside A) up to 40%. The treatment also increased transcripts accumulation of genes enrolled in SG biosynthesis, such as SrKA13H, SrUGT85C2, and SrUGT76G1, indicating SG pathway become more active due to the inhibition of GA pathway. Furthermore, the inhibition of GA was also indicated by the upregulated expression of GA biosynthesis gene (GA3ox) as the result of feedback regulation, and the downregulated expression of GA catabolism gene (GA2ox2) as the result of feed-forward regulation caused by inhibitor treatment.

Multiple shoots were obtained from both shoot tips and nodal segments cultured on MS fortified with different concentrations of BAP and Kn singly or in combination with low concentration of NAA. Maximum number of shoots (9.28 ± 0.61) were found on MS supplemented with 1.5 mg/l BAP and 05 mg/l NAA. In vitro regenerated shoots were separated and transferred onto half and full-strength MS supplemented with different concentration of IBA, IAA and NAA for root induction. Full strength MS containing 0.2 mg/l IBA was found to be best for root induction where 93.33% shoots were rooted. In vitro regenerated plants grew normally without showing any morphological variation and flowered after 40 days of transplantation.

Psychotria ipecacuanha, is a plant species with known medicinal properties that is critically endangered due to overexploitation of natural populations. Although the difficulties in conventional propagation by seed and by vegetative propagation are generally understood, the present study enhances our knowledge by describing efficient plant regeneration and root induction protocols for P. ipecacuanha while comparing alkaloid content (emetine and cephaeline) in in vitro-derived tissues. Stem node explants were cultured on MS medium MS supplemented with indolbutiric acid (IBA) in semi-solid media and the RITA® temporary immersion bioreactor. The highest root formation (81%) was in MS + 1.5 mg L−1 IBA in the bioreactor. After 24 months of acclimatization, the plants cultivated in MS + 0.50 and 1.0 mg L-1 of IBA had the highest number of roots (3), with mean values of 10.47 and 9.40 cm, respectively. The cultures coming from 1.0 mg L−1 and 0.5 mg L−1 IBA in the bioreactor contained higher cephaeline content, with a relative area of 14.2 and 14.9%, respectively. For emetine, the 1.0 mg L−1 IBA cultures in the bioreactor, 0.5 mg L−1 IBA and MS0 cultures contained higher content than the other treatments, with a relative area of 10.2, 10.2 and 10.1%, respectively.

Habanero Pepper

This article describes the performance of nodal segments from Habanero pepper (Capsicum. chinense) during shoot induction and elongation under different semisolid and liquid culture conditions with various degrees of ventilation in which they were exposed to different levels of immersion and growth regulators. The ethylene content in non-ventilated containers, the age of the explant donor plants as well as the effect of thidiazuron and paclobutrazol on shoot induction and of gibberellic acid and AgNO3 on shoot elongation were also evaluated. A temporary immersion bioreactor (BioMINT™) was used for the multiplication and elongation of isolated shoots with very good results. We report an efficient protocol for the in vitro propagation of Habanero pepper that produces plants with a high survival rate when transplanted to soil.
