Abstract

Alocasia azlanii is a unique species that has an ornamental value, native to Southeast Asia. The present investigation aimed to develop reliable in vitro propagation techniques for A. azlanii, suitable for potential mutation and polyploidization programs. The in vitro propagation protocol for these species includes sterilization, shoot proliferation, in vitro rooting induction, and acclimation stages. The results showed that the effective protocol for freeing the explants from contamination was achieved through additional pre-treatment with bactericide and fungicide, which produced the best percentage of clean shoot-tip explants (87%). At the shoot multiplication stage, the shoot-tip explant cultivated in MS medium supplemented with 0.05 mg/l TDZ and 1 mg/l BAP showed the highest number of shoots (31.8) in the second subculture cycle. In rooting stages, single shoots that were planted in MS medium supplemented with 0.5 mg/l activated charcoal and 0.5 mg/l NAA resulted in the best plantlet performances in terms of stem diameter, number of roots, number of leaves, and plantlet height. In the acclimatization stage, planting media composed of husk charcoal, soil, manure, and volcanic fine sand mixture (2:1:1:1 v/v) preserved vigorous plantlet development, with 93% survival.

Abstract

The Husk Tomato (Physalis angulata L.) has been valued as a medicinal plant due to its rich secondary metabolites. These compounds include physalins, which exhibit antitumor activity; withanolides, recognized as potent anti-inflammatory agents; and other components such as flavonoids, phenolic acids, alkaloids, and carotenoids. Despite its therapeutic potential, the commercial utilization of P. angulata remains limited by inconsistent fruit quality. This review summarizes current knowledge on Indonesian P. angulata germplasm, focusing on its botany, growth characteristics, genetic diversity, and metabolite profiles. Previous reviews mainly discussed botanical and pharmacological properties, whereas this review emphasizes Indonesian germplasm diversity and breeding perspectives. We critically evaluate several breeding strategies aimed at improving fruit quality, including the utilization of genetic resources, hybridization, mutation breeding, polyploidization, and in vitro techniques. Furthermore, we highlight the application of genetic engineering, particularly the overexpression of the squalene synthase (SQS) gene, suggesting that this approach could efficiently enhance the biosynthesis of squalene derivatives, such as physalins and withanolides. By evaluating the achievements and challenges of these strategies in P. angulata and other Solanaceae species, this review offers a roadmap for future research, aiming to maximize fruit quality and unlock the extensive biopharmaceutical applications of the Indonesian Husk Tomato.
