Abstract

Background: THYMOL and CARVACROL are the two important secondary metabolites from THYMUS VULGARISthat productions of them are controlled by genetic and environmental factors.Objective: Evaluation of Water stress effects on expression of three important genes of THYMOL and CARVACROL biosynthetic pathway and also physiological and phytochemical properties of THYMUS VULGARIS.Methods: The present study was conducted in a randomized complete block design with 4 treatments and 3 replications in Institute of Medicinal Plants, ACECR, Karaj. For this purpose, the treatments were selected as control (FC), 70% of FC, 40% of FC, and 20% of FC. GENE EXPRESSION was studied using real-time PCR method, and HPLC was applied to essence analysis. Also physiological characteristic including chlorophyll content, relative water content, electrolyte leakage percentage and carotenoids content were analyzed.Results: The results revealed that water stress significantly influenced the GENE EXPRESSION (P£ 0.05). The highest GENE EXPRESSION of DXR and Tctps5 was observed in 70% of FC, while the highest one of TvTPS 1 was recorded in 40% of FC. Moreover, the maximum THYMOL and CARVACROL was found in 70% of FC. In other hand the highest chlorophyll content and corotenoids content were obtained in 100% and 70% of FC respectively. Also there were not significant differences between treatments for relative water content and electrolyte leakage percentage.Conclusion: The 70% of FC through influencing of genes in the firs and last of MEP pathway increased THYMOL and CARVACROL production.
