tall wheatgrass (agropyronelongatum) is native to iran and is used in a wide area of rangelands and also used in drylandseeding program. this plant produces green and dry fodder and has a great importance in protecting drylands from water and wind erosion.seed proteome analysis was conducted under three conditions, namley, optimum (20 °c and zero water potential), drought conditions (20 °c and ...

BACKGROUND AND OBJECTIVE Protein expression in colon and rectal cancer (CRC) and paired normal tissues was examined by two-dimensional gel electrophoresis (2-DE) to identify differentially expressed proteins. MATERIALS AND METHODS Five fresh colorectal cancer and paired adjacent normal tissues were obtained and differentially expressed protein spots were determined using PDQuest software, wit...

background: in this study, two-dimensional gel electrophoresis (2-de) method was applied to determine and compare the protein spots expressed in the two field isolates of leishmania major and recovered from the patients who were clinically sensitive and resistant to glucantime® treatment. methods: leishmania parasites were isolated from the cutaneous lesions of two cl infected patients in shira...

to better understand seed dormancy breaking of bread wheat (triticum aestivum l.rl4137), we examined protein synthesis in dormant and after-ripened seeds.we used six treatments including dormant seed, dormant seed that were subjected to gibberllic acid (ga3) for 10 hours, dormant seed with one, three and six weeks of after-ripening and finally six weeks after-ripened seed subjected to abscisc a...

background: the tp53 gene is the most important tumor suppressor gene in humans. the aim of our study was to determine the genotype frequency of three common tp53 polymorphisms (codon 72 bstui and intron 6 mspi, as well as the intron 3) in a group of iranian women with and without breast cancer. methods: paraffin-embedded specimens of 65 malignant breast cancer cases and 65 cases with benign br...

a proteomic approach was conducted to further understand the mechanism of plant responses to salinity in hordeum bulbosom. three-week-old seedlings were treated with 300 mm of nacl for 21 days. total proteins of fourth leaf were extracted and separated by two-dimensional gel electrophoresis. more than 500 protein spots were reproducibly detected, including 46 spots that were up-regulated and 16...

saprophitic pseudomonas species are root-colonizing bacteria that can improve plant health. efficient exploitation of these bacteria in agriculture requires knowledge of traits that enhance ecological performance in the rhizosphere. some pseudomonas fluorescens strains present biocontrol properties, protecting the roots of some plant species against plant pathogens. these bacteria induce system...

Three fractions (male germ unit [MGU]-rich, cytoplasmic-particulate and water-soluble proteins) were isolated from pollen of Plumbago zeylanica L. Proteins were extracted using a phenol procedure and polypeptide patterns were compared on one- and two-dimensional polyacrylamide gels. The MGU-rich fraction contains the sperm and vegetative nucleus of the pollen grain and yielded 427 spots >33 kil...
