Calotropis procera accumulates Uzarigenin and Calotropagenin in response to environmental lighting and drought

Abstract

Calotropis procera (C. procera) was evaluated as a pharmaceutically useful plant and for its therapeutic effects in the most significant studies. Uzarigenin and Calotropagenin are significant components of this plant that have pharmacological effects on certain systems, including the digestive, immunological, and focal, and peripheral sensory systems. In this study, pathway genes are extracted from high throughput data acc.no. SRR1554320. Seven critical enzymes are involved in studying the effects of sunlight on the formation of Uzaragenin and Calotropagenin in C. procera before and after irrigation. Molecular identification and NCBI submission of six enzyme genes were successful; HSD (acc.no. OQ091761) for 3β-hydroxystroid dehydrogenase, OR (acc.no. OQ091762) for 5beta-pregnan oxidoreductase, MO (acc.no. OQ091763) for Pregnan monooxygenase, HOX (acc.no. OQ091764) for Steroid hydroxylase, MAT (acc.no. OQ091765) for Melonyletransferase, UHOX (acc.no. OQ091766) for Uzarigenin hydroxylase. During dawn after irrigation, the Uzargenin pathway showed the highest activity, however midday after irrigation was the lowest. The most period that showed high activity for the Uzargenin pathway was dawn after irrigation, however, midday after irrigation was the lowest. This data is confirmed by chromatography analysis (UPLC) to calculate the accumulation of Uzarigenin and Calotropagenin in different periods.
