in the present study, we aimed to screen indigenous rhizospheric bacillus strains, capable of producing antiphytopathogenic and plant growth promoting traits. isolate cts-b19 and cts-g24 exhibited quite noticeable antagonistic activity initially against fusarium oxysporum f. sp. ciceri and rhizoctonia bataticola, and, later, against a panel of phytopathogens. partial 16s rrna sequence analysis ...

effects of excess concentrations of boron on major cell wall components of tobacco cells(nicotiana tabacum l. cv. burley 21) were studied. pectin, xyloglucan, hydroxyproline-richglycoproteins (extensin), and arabinogalactan proteins were characterized. results showedthat increased boron supply resulted in significant decrease in cell and cell wall dry weights.also, high concentrations of boron ...

in the past decade much effort has been devoted to the development of new expression systems and novel techniques for the surface display of heterologous proteins in yeast in order to improve their applications in biotechnology, food technology, pharmacology and medicine. heterologous protein-encoding genes are generally fused with genes coding for yeast cell wall proteins or their fragments re...

berangan banana were treated with hot water at 50 ºc for 0 (control), 10, and 20 min and then kept at room temperature (25±2 ºc), 75-80% rh to observe the ripening progress. firmness and activity of cell wall degradation enzymes such as polygalacturonase (pg), pectin methylesterase (pme), and pectate lyase (pl) were determined for treated and untreated banana. the microstructure of banana peel ...

background: chronic myeloid leukemia is a common cancer in human and chemical therapy is a routine method for treatment that has some side effects. so the goal of this study was the use of natural compound such as cell wall obtained from saccharomyces cerevisiae ( s. cerevisiae ) and saccharomyces boulardi ( s. boulardi ) and iron nanoparticles on the growth inhibition of k562 cell line. method...

this experiment was conducted to investigate the effect of different levels of saccharomyces cerevisiae cell wall on performance, carcass traits and intestinal morphology in broilers. in this experiment 240 ross- 308 broilers were used in 4 treatments, 5 replicates and 12 bird in each replicate in a completely randomized design for 42 days. the treatments included: 1) control group (without sac...

Wood is a porous three dimensional, hydroscopic, viscoelastic, anisotropic bio-polymer composite composed of an interconnecting matrix of cellulose, hemicelluloses and lignin with minor amounts of inorganic elements and organic extractives. Some, but not all, of the cell wall polymer hydroxyl groups are accessible to moisture and these accessible hydroxyls form hydrogen bonds with water. As the...

we report occurrence of a rare case of giant cell tumor (gct), in a 28-year old woman, arising from anterior arc of right 6 th rib during pregnancy. it progressed rapidly during breast-feeding period, mimicking malignant bone tumor at delayed presentation.

expansin proteins are a type of cell-wall loosening proteins which able to cell wall expansion in ph-dependent manure without hydrolyze of main cell wall structures. the arabidopsis expa1 exhibit guard cell specific expression and trigger the stomatal movements. the objectives of this study were to transfer the atexpa1 gene into tobacco plants and evaluate their phonotypic effects on transforme...
