Metabolite profiling and molecular responses in a drought-tolerant savory, Satureja rechingeri exposed to water deficit.

ABSTRACT: This study aimed to determine the response of Satureja rechingeri to water deficit by quantifying the expression of three targeted genes and four traditional reference genes using quantitative real-time PCR analysis (RT-qPCR). Drought stress was imposed by withholding water 4 months after planting. Profiling of volatile and non-volatile compounds using gas chromatography/mass spectrometry (GC/MS) and high-performance thin layer chromatography (HPTLC) showed an increasing-decreasing trend of major phenolic and terpenoid compounds such as rosmarinic and caffeic acids, carvacrole, thymol and p-Cymene. Drought stress also lead to significant increases in oil yield, soluble sugars and proline as well as significant reductions in leaf water potential (LWP), relative water content (RWC), a
