We studied the effect of genetic transformation on biologically active compound (artemisinin and its co-products (ART) as well as sugars) accumulation in Artemisia vulgaris and Artemisia dracunculus "hairy" root cultures. Glucose, fructose, sucrose, and mannitol were accumulated in A. vulgaris and A. dracunculus "hairy" root lines. Genetic transformation has led in some cases to the sugar content increasing or appearing of nonrelevant for the control plant carbohydrates. Sucrose content was 1.6 times higher in A. vulgaris "hairy" root lines. Fructose content was found to be 3.4 times higher in A. dracunculus "hairy" root cultures than in the control roots. The accumulation of mannitol was a special feature of the leaves of A. vulgaris and A. dracunculus control roots. A. vulgaris "hairy" root lines differed also in ART accumulation level. The increase of ART content up to 1.02 mg/g DW in comparison with the nontransformed roots (up to 0.687 mg/g DW) was observed. Thus, Agrobacterium rhizogenes-mediated genetic transformation can be used for obtaining of A. vulgaris and A. dracunculus "hairy" root culture produced ART and sugars in a higher amount than mother plants.

Carnosol (CO) and carnosic acid (CA) are pharmaceutically important diterpenes predominantly produced in members of Lamiaceae, Salvia officinalis (garden sage), Salvia fruticosa and Rosmarinus officinalis. Nevertheless, availability of these compounds in plant system is very low. In an effort to improve the in planta content of these diterpenes in garden sage, SmERF6 (Salvia miltiorrhiza Ethylene Responsive Factor 6) transcription factor was expressed heterologously.

WRKY transcription factors (TFs) play pivotal roles in regulating plant nutrient uptake, particularly phosphate (Pi) acquisition, and biosynthesis of secondary metabolites. Euphorbia lathyris, a significant medicinal plant with diverse pharmacological activities, lacks a systematic analysis of WRKY members and their functional roles. In this study, 58 ElWRKY genes were identified in the E.

C-low threshold mechanoreceptors (C-LTMRs) in animals (termed C-tactile (CT) fibres in humans) are a subgroup of C-fibre primary afferents, which innervate hairy skin and respond to low-threshold punctate indentations and brush stimuli. These afferents respond to gentle touch stimuli and are implicated in mediating pleasant/affective touch. These afferents have traditionally been studied using low-throughput, technically challenging approaches, including microneurography in humans and teased fibre electrophysiology in other mammals.

Houtt. is the source of various phenolic compounds: phenolic acids, flawan-3-ols, and stilbenes, with a broad range of biological activity. The rhizome (underground organ of these plants) is abundant in secondary metabolites but, in natural conditions, may accumulate various toxic substances (such as heavy metals) from the soil.
