Abstract. Prasetya DN, Hamim, Sulistyaningsih YC. 2022. Physiological and ultrastructural studies of Jatropha curcas and Reutealis trisperma in response to gold-mine tailings. Biodiversitas 23: 3471-3479. Heavy metal contamination through tailings from mining pollutes the environment and harms human health. This study aimed to analyze physiological, especially ultrastructural changes and the photosynthetic activities of Jatropha curcas and Reutealis trisperma in response to gold mine tailings. J. curcas and R. trisperma were grown in 8 kg of polybags and treated with 0%, 50%, and 100% gold mine tailings for three months before examining their morphological, physiological, and leaf ultrastructure. The results showed that gold mine tailings with 50% and 100% concentrations affected the growth of both species. This was indicated by reduced plant height, total leaf number, shoot, root dry weight, and decreased chlorophyll and carotenoid content. Furthermore, treatment of gold mine tailing at 50% and 100% induced lipid peroxidation, indicated by the significant increase in leaf malondialdehyde content. The photosynthetic and transpiration rates at 90 days after treatment decreased with the increase in gold mine tailings concentration. The leaf ultrastructure analysis showed high-level tailings of treatment-induced ultrastructure alteration of J. curcasand R. trisperma. However, these changes did not significantly affect the photosynthesis rate, hence the plants survived until the end of the observation period. The overall effect of tailings on R. trisperma was lower than on J. curcas, suggesting that R. trisperma had higher adaptability than J. curcas.

Abstract

ARTICLE HIGHLIGHTS- Information on salinity-tolerant mulberry accessions is currently unavailable. This research reveals the discovery of salinity-tolerant mulberry accessions from the exploration of various mulberry accessions in Indonesia.- Salinity-tolerant mulberry accessions can be utilized for sustainable development and biodiversity conservation.- Salinity stress treatment is known to increase secondary metabolites in mulberry plants.- Profiling of secondary metabolites in mulberry plants in response to salinity stress is known.- The integration of metabolomics and ecophysiology offers a new perspective on how plants adapt to stress.ABSTRACTLand salinity in Indonesia continues to increase, therefore research is needed to obtain saline-resistant plants such as mulberries. Mulberry plants are well recognized for their resilience to various abiotic stresses, including salinity. This study aimed to identify tolerant accessions to salinity stress, in accordance with their growth characteristics, and to examine the alterations in secondary metabolites as a reaction to salt stress. The experiment was designed using a factorial randomized block design, which included seven mulberry accessions, identified as MB1 through MB7, and varying NaCl concentrations of 0% (control), 0.2%, 0.3%, and 0.4%. The study’s results showed that MB2-3 accession tolerates high salinity stress by accumulating proline, flavonoid compounds, phenolic and dissolved sugars, as well as secondary metabolites, with increasing NaCl concentration. Based on the results of UHPLC-Q-Orbitrap HRMS analysis of mulberry leaf extract, 100 selected metabolites were obtained. The heat map results showed metabolic substances such as phenylpropanoids, organic acids, lipids, and carbohydrates increased in response to salinity stress. The integration of metabolomics and ecophysiology called ecophysiolomics offers a new perspective on how plants adapt to stress. By analyzing the involvement of metabolites that facilitate tolerance to salinity stress, we can gain a valuable understanding of how mulberry plants endure this environmental challenge..
