Physiological and Molecular Aspects of Two Species Differently Sensitive to Drought Stress.

Drought is one of the most important threats to plants and agriculture. Here, the effects of four drought levels (90%, 55%, 40%, and 25% field capacity) on the relative water content (RWC), chlorophyll and carotenoids levels, and mRNA gene expression of metabolic enzymes in (as sensitive to drought) and (as a drought-tolerant species) were evaluated. The physiological results showed that the treatment predominantly affected the RWC, chlorophyll, and carotenoids content.

Biological Response of to Brassinolide Treatment under Different Watering Conditions.

() is an important dry season medicinal plant. Drought, an important abiotic stress, adversely affects the plant's metabolism, which can be alleviated by plant growth regulators like brassinolides. A two-year field experiment was conducted in 2017-2018 to determine the effects of three different irrigation regimes and four brassinolide concentrations on the biochemical properties.

Variation in Terpene Profiles of in Water Deficit Stress Response.

Thyme (.) volatiles predominantly consisting of monoterpenes and sesquiterpenes, serve as antimicrobial, antiseptic and antioxidant in phytomedicine. They also play a key role in plants as secondary metabolites via their potential role against herbivores, attracting pollinators and abiotic stress tolerance.

FTICR mass spectrometry-based multivariate analysis to explore distinctive metabolites and metabolic pathways: A comprehensive bioanalytical strategy toward time-course metabolic profiling of Thymus vulgaris plants responding to drought stress.

In this research, metabolic profiling/pathways of Thymus vulgaris (thyme) plant were assessed during a water deficit stress using an FTICR mass spectrometry-based metabolomics strategy incorporating multivariate data analysis and bioinformatics techniques. Herein, differences of MS signals in specific time courses after water deficit stress and control cases without any timing period were distinguished significantly by common pattern recognition techniques, i.e.

Effect of drought stress on metabolite adjustments in drought tolerant and sensitive thyme.

Drought is one of the most important threats to plants and agriculture; therefore, understanding of the mechanism of drought tolerance is crucial for breeding of drought tolerant plants. Here, we assessed effects of four levels of drought (90%, 55%, 40% and 25% FC) on some physiological criteria and metabolite adjustment of two different drought-responsive thyme plants (Thymus vulgaris as drought sensitive and T. Kotschyanus as drought tolerant species), using H-NMR.

Evaluation and validation of housekeeping genes in two contrast species of thyme plant to drought stress using real-time PCR.

To decrease errors and increase accuracy and reliability of quantitative real-time PCR (qRT-PCR) results, the use of a reference gene is inevitable. Despite the industrial importance of genus Thymus, not any validated reference gene has not been reported for T. kotschyanus and T.

Lipidomics Unravels the Role of Leaf Lipids in Thyme Plant Response to Drought Stress.

is one of the best known genera within the Labiatae (Lamiaceae) family, with more than 200 species and many medicinal and culinary uses. The effects of prolonged drought on lipid profile were investigated in tolerant and sensitive thyme plants ( L. and L.

Comprehensive list of metabolites measured by DI-FTICR mass spectrometry in thyme plants with contrasting tolerance to drought.

This article contains data related to the main research entitled "Metabolomic approach reveals the biochemical mechanisms underlying drought stress tolerance in Thyme" (Moradi et al., 2017) [1]. Two thyme populations with contrasting drought tolerance were subjected to long term water deficit.

Metabolomic approach reveals the biochemical mechanisms underlying drought stress tolerance in thyme.

Thyme as a perennial herb has been recognized globally for its antimicrobial, antiseptic and spasmolytic effects. In this investigation, we have used non-targeted metabolite and volatile profiling combined with the morpho-physiological parameters in order to understand the responses at the metabolite and physiological level in drought sensitive and tolerant thyme plant populations. The results at the metabolic level identified the significantly affected metabolites.

Buxtonella spp. like infection in cattle in Sanandaj province, Iran.

Buxtonellosis is a disease caused by the ciliated protozoan Buxtonella sulcata (Jameson, 1926). B. sulcata is a common protozoan of ruminants and may result in subclinical infection or clinical disease including diarrhea.

Investigation of DNA-cationic bolaform surfactants interaction with different spacer length.

In this paper interaction of DNA with cationic bolaform surfactants is investigated. The structural formula for synthesized bolaforms is as follows: bolaform B1 with structural formula Br(-)(CH3)3N(+)(CH2)3N(+)(CH3)Br(-) and bolaform B2 with structural formula of Br(-)(CH3)3N(+)(CH2)12N(+)(CH3)Br(-). There are stronger electrostatic interactions in bolaform B1 due to shorter spacer length, while there are stronger hydrophobic interactions in bolaform B2 compared to bolaform B1 due to existence of 12 carbons in hydrocarbonic chain.
