The RNA-directed DNA methylation pathway (RdDM) can be divided into three phases: (i) small interfering RNA biogenesis, (ii) de novo methylation and (iii) chromatin modification. To determine the degree of conservation of this pathway we searched for key genes amongst land plants. We used OrthoMCL and the OrthoMCL Viridiplantae database to analyse proteomes of species in bryophytes, lycophytes,...

the plant salvadora persica is used for oral hygiene in many parts of the world. it has been suggested that it has antibacterial properties, in addition to its ability to mechanically remove plaques. the aim of this study was to assess the antimicrobial activity of the herbal product persica containing salvadora persica against periodontopathogens porphyromonas gingivalis and aggregatibacter ac...

Tick-borne relapsing fever (TBRF) is an arthropod-borne infection found in the Middle East, Africa, Europe and North America. The disease is caused by several species of Borrelia and transmitted by various species of soft ticks [1,2]. Specific relationships usually exist between Borrelia species, the vector ticks and the distribution area [3]. Ornithodoros tholozani is distributed in the Middle...

The interactive effects of three non-fodder Indian arid plant species, Tephrosia purpurea, Aerva persica, and Calotropis procera, four Aspergillus fungal species on soil enzymes (acid alkaline phosphatase, -glucosidase, dehydrogenase, urease, amidase activities) were temporally assessed (15 30 days withdrawals). results statistically analysed using ANOVA, Principal Component Analysis (PCA), Can...

Penetration of second-stage juveniles (J2) of Meloidogyne incognita into tomato root explants and in vitro propagated peach plantlet roots were compared. Five inoculum levels were used: 25, 50, 75, 100, and 200 J2 for tomato; and 50, 100, 200, 500, and 1,000J2 for peach. The greatest root penetration into tomato was 30% at the 75 J2 level, but the maximum penetration into peach roots was only 8...

The influence of two carbon sources, sorbitol and sucrose on In vitro shoot proliferation and rooting of peach rootstock GF 677 was compared at 15, 30, 45 and 60 g l concentrations. The highest number of shoots per proliferated explant, usable shoots and shoots having maximum fresh weight were obtained on sorbitol at 30 g l. GF 677 does not seem to be an efficient utilizer of sucrose for In vit...

A simplified method for building three-dimensional (3D) mock-ups of peach trees is presented. The method combines partial digitizing of tree structure with reconstruction rules for non-digitized organs. Reconstruction was applied at two scales: leaves on current-year shoots (CYS) and shoots on 1-year-old shoots (OYOS). Reconstruction rules make use of allometric relationships, random sampling o...

otostegia persica (burm.) boiss. is used for the treatment of various diseases in traditional medicine. the aim of this study was to assess the effects of hydroalcoholic extract of the aerial parts of o. persica in dexamethasone (dex) induced hypertension in male wistar rats. for induction of hypertension, dex at 30 µg/kg/day was administered subcutaneously for 14 days. in a prevention study, a...

plants produce a diverse array of secondary metabolites, many of which have antimicrobial activity. otostegia persica bioss. (labiatae) grows in south east of iran. no previous investigation on antimicrobial effects of this plant has been reported. thus, the aim of this work was to examine the antimicrobial effect of o. persica extracts with different polarity on several microorganisms. aerial ...

Objective: To evaluate the hepatoprotective properties of Otostegia persica (O. persica) ethanol extract on carbon tetrachlo‌‌ride-induced liver damage in rats. Materials and Methods: Fifty adult male Wistar rats were randomly divided into five groups. Group I served as normal control and was given only olive oil intraperitoneally (i.p.). Group II, III, IV, and V were administered CCl4 mixed wi...
