In the present study, an efficient protocol has been developed for callus induction and production of RA in callus culture of Satureja khuzistanica for the first time. In vitro callus induction was achieved from young shoot tip explants cultured on MS and B5 media supplemented with different concentrations of IBA (0.1, 1.0, 2.0 and 5.0 mgl-1) solely or in combination with cytokinins BAP and KIN...

Gliding motility is critical for normal development of spore-filled fruiting bodies in the soil bacterium Myxococcus xanthus. Mutations in mgl block motility and development but one mgl allele can be suppressed by a mutation in masK, the last gene in an operon adjacent to the mgl operon. Deletion of the entire 5.5 kb masABK operon crippled gliding and fruiting body development and decreased spo...

Purpose To investigate whether the subcellular distribution of endocannabinoid (eCB) system (ECS) components in growing RGC axons is consistent with the formation of eCB-enriched "hotspots" and the role of the ECS in RGC axonal growth. Methods We used immunocytochemistry and image analysis to quantify axonal expression of the ECS components diacylglycerol lipase alpha (DGLα), monoacylglycerol...

Hospital wastewater contains pathogenic agents and hazardous compounds; so, it will cause many risks on environmental and human health of different communities. The aim of this research was to investigate the efficiency of hospital wastewater treatment plant in north of Iran. This cross-sectional descriptive research was done on four hospital wastewater treatment plant in north of Iran during 2...

Dendritic cells (DCs) are key to the maintenance of peripheral tolerance to self-antigens and the orchestration of an immune reaction to foreign antigens. C-type lectins, expressed by DCs, recognize carbohydrate moieties on antigens that can be internalized for processing and presentation. Little is known about the exact glycan structures on self-antigens and pathogens that are specifically rec...

Relying on results of Hopkins-Morel, we show that, for X a quasiprojective variety over a field of characteristic zero, the canonical map Ωn(X)→ MGL 2n,n (X) is an isomorphism.

the present research was carried out to evaluate the response of seven selected persian leek accessions to in vitro gynogenesis. the experimental design was a factorial one based upon a completely randomized design of three culture media treatments b2d0 (2 mgl-1 ba), b2d2 (2 mgl-1 ba and 2 mgl-1 2, 4-d), and b2d4 (2 mgl-1 ba and 4 mgl-1 2, 4-d) along with seven persian leek accessions (gorgan, ...

dog rose (rosa canina l.) is one of the most important ornamental and medicinal plants which are used as a rootstock for ornamental roses such as rosa hybrid and rosa floribunda. in vitro propagation of rose has a very important role in rapid multiplication of species with desirable traits and in production of healthy and disease-free plants. micropropagation of rosa canina l. was revised, usin...
