Abstract
Physalis peruviana L. (Cape gooseberry) is a source for a variety of phytocompounds such as withanolides, withanone,withaferin A, and withanolide A. These withanolides are high-value drug candidates due to their various pharmacological properties.To meet the increasing demands for these compounds, plant cell technology offers a reliable alternative. Exogenous addition of elicitorsis considered the most effective strategy for enhanced production of secondary metabolites. In this study, we investigated changes inwithanolide accumulation and characterized the gene expression level changes of squalene synthase enzyme in P. peruviana shootcultures exposed to mild nonlethal heat stress (45°C for 2 and 5 h) and UV-B radiation (313 nm for 15 min and 3 h). We demonstratedsignificant changes in withanolide content with 7.86- and 12.5-fold increases for 2- and 5-hmild high-temperature exposure times,respectively. Exposure to UV-B also changed the withanolide content by 7.22- and 7-fold increases for 15 min and 3 h exposure times,respectively. The relative expression level of squalene synthase gene showed consistent results with1.80- and 10.13-fold increases inwithanolide for 2- and 5-h mild high-temperature exposure times, and 1.34- and 2.01-fold increases with 15 min and 3 h UV-B exposuretimes, respectively
