The genus Thymus is perennial medicinal plants belong to the Lamiaceae familythat is used for different propose in pharmaceutical industry. Environmental stresses,particularly salinity, are considered as the major factor reducing plant growth. The purpose ofthis study was to investigate the effects of salt stress on germination characteristics andseedling morphology in two medicinal species of ...

Fungal cell walls and fragments thereof (elicitors) induce the formation of low and high molecular weight defense compounds in plant cell suspension cultures. This induced synthesis requires a signal molecule transmitting the message between the elicitor plant cell wall receptor and gene activation. We demonstrate in this study that cis-jasmonic acid is rapidly synthesized in plant cell culture...

Abstract Several species of thymus have therapeutic properties, so they are used in traditional medicine. In this work was carried out to synthesize Thymus vulgalis silver nanoparticles (TSNPS) and evaluate antioxidant antimicrobial activities TSNPS T. essential oil extract (TEOE). The oils analyzed by GC-MS were characterized. Major compounds phenol, 2 methyl 5 (1 methylethyle) (CAS), thymol 1...

Jasmonic acid and related oxylipins are controversially discussed to be involved in regulating the initiation and progression of leaf senescence. To this end, we analyzed profiles of free and esterified oxylipins during natural senescence and upon induction of senescence-like phenotypes by dark treatment and flotation on sorbitol in Arabidopsis (Arabidopsis thaliana). Jasmonic acid and free 12-...

background & aim: in present study, some of the iranian endemic medicinal plants were used to evaluate potential as well as therapeutic agent and immunostimulants in aquaculture. the essential oils of five species from leaves and inflorescence were used to determinate the effects on immune system in rainbow trout (oncorhynchus mykiss). experimental: the experimental in a completely randomiz...
