| Colletotrichum truncatum is the most common pathogen fungus associated with soybean anthracnose. Although the lignin-degrading enzyme laccase has been implicated in pathogenicity of a wide range of plant pathogenic fungi, its biological role in the Colletotrichum -soybean disease system is unknown. The extent of the infection in our country led us to examine laccase production in Argentinean Colletotrichum strains isolated from diseased soybean plants from different geographic locations. Ten strains (eight of them identified as C. truncatum) , were screened for in vitro laccase production. Only six of the isolates, all of them C. truncatum , produced laccase activity when cultured on a defined medium based on pectin and asparagine as carbon and nitrogen... |

| The cyanobacterium Oscillatoria agardhii was isolated from the fresh water Mawatha lake, Jaipur and was grown in Zarrouk's medium at 25 ± 2°C, illuminated with white fluorescent light at the intensity of 2 500 lux with 12:12 h light and dark photoperiod. The effects of photoperiod and temperature on the growth and protein expression by Oscillatoria agardhii were studied under different controlled culture conditions (ALR, ALC, CLR, CLC, and NDL), measuring optical density, cell count and dry weight. Protein content was measured quantitatively by Bradford assay and qualitatively by SDS-PAGE. The densitometric analysis was also carried out for the measurement of the expression level of different proteins/peptides under different culture conditions. Maximum... |

| ABSTRACT Quail is an important and interesting group of galliform birds. The Common quail (Coturnix coturnix); the Japanese quail (Coturnix japonica); the Panda quail (Coturnix japonica); the Dotted white quail (Coturnix japonica) and the Bobwhite quail (Colinus virginianus) were used in this study. PCR-RFLP and SDS-proteins were performed to reveal the genetic characterization and genetic relationship of the studied quails. Analysis of fragments generated by digestion of PCR product with restriction enzyme NlaIII recorded highly polymorphic restriction profiles. There is a wide intraspecific COI, SEMA3E and TLX genes variability among the studied quails. Protein bands varied from10 to 18 between quails with minimum number of bands were in the Dotted... |

| ABSTRACT The rhizosphere zone has been defined as the volume of soil directly influenced by the presence of living plant roots or soil compartment influenced by the root. During the growing season of 2014, the rhizobacteria of 23 sugar beet plants sampled from 12 sites in the west and north west of Iran were inventoried. Using a cultivation-dependent approach, a total of 217 bacteria were isolated from the rhizosphere. The bacterial isolates were tentatively grouped and documented based on polyacrylamide gel electrophoresis of whole-cell proteins and were found to represent 43 different protein electrotypes. The majority of the fingerprint types were found only on a single occasion. Fifty-nine percent of the strains belonged to the five bacterial species... |

| We have characterized, in the Paracoccidioides brasiliensis yeast phase, an exocellular SH-dependent serine proteinase activity against Abz-MKRLTL-EDDnp and analogous fluorescent-quenched peptides, and showed that it is also active against constituents of the basement membrane in vitro. In the present study, we separated the components of P. brasiliensis culture filtrates by electrophoresis and demonstrated that the serine-thiol exocellular proteinase has a diffuse and heterogeneous migration by SDS-PAGE, localizing in a region between 69 and 43 kDa. The hydrolytic activity was demonstrable after SDS-PAGE using buffered agarose overlays of Abz-MKALTLQ-EDDnp, following incubation at 37oC, and detection of fluorescent bands with a UV transilluminator.... |

| Sichuan basin, situated in the west of China, is the fourth biggest basin in China. In order to describe a systematic study of the cry2-type genes resources from Bacillus thuringiensis strains of Sichuan basin, a total of 791 Bacillus thuringiensis strains have been screened from 2650 soil samples in different ecological regions. The method of PCR-restriction fragment length polymorphism (PCR-RFLP) was used to identify the type of cry2 genes. The results showed that 322 Bacillus thuringiensis strains harbored cry2-type genes and four different RFLP patterns were found. The combination of cry2Aa/cry2Ab genes was the most frequent (90.4%), followed by cry2Aa (6.8%) and cry2Ab alone (2.5%), and only one novel type of cry2 gene was cloned from one isolate... |

| The aim of the present research was to evaluate the protein polymorphism degrees among forty-eight C. albicans isolates from fourteen anatomical sites of clinical patients by polyacrylamide gel electrophoresis (SDS-PAGE) and numerical analyzes, in order to identify subspecies and their similarities in some infectious niches. Cell cultures were grown in YEPD medium, collected by centrifugation, and washed in cold saline solution. The whole-cell proteins were extracted by cell disruption using glass beads and submitted to SDS-PAGE technique. After electrophoresis, the protein bands were stained with coomassie-blue and analyzed by statistics package NTSYS-pc version 1.70 software. Similarity matrixes and dendrograms were generated by application of similarity... |

| Electrophoretic protein profiles of Campylobacter jejuni subsp. jejuni strains isolated from feces of seven animal species, including man, were compared. Fourteen strains (two from each species) plus two human strains and the reference one, were ruptured by ultrasound and their total soluble proteins were analyzed by SDS-PAGE technique in a 12% polyacrylamide gel with computerized densitometric reading by the molecular analyst software. All the strains had bands in common that correspond to 45 and 66 Kda molecular weight. The disagreement corresponded to a 97 to 200 Kda molecular weight region. From the 17 strains, 13 (76.5%), were classified as biotype I, three (17.6%) as biotype II and one (5.8%) as biotype III. Since protein extracts were obtained from... |

| Com o objetivo de avaliar a influência da retenção de placenta (RP) no proteinograma de fêmeas bovinas da raça Holandesa, de propriedades comerciais, foram utilizadas 129 vacas com RP e 145 vacas com parto e pós-parto fisiológicos e sem nenhum tratamento no período avaliado. As amostras de sangue foram divididas nos momentos: 1odia pós-parto (DPP), 2o-3o, 4o-5o, 6o-7o, 8o-14o, 15o-29o, 30o-59o e 60o-90o DPP. O fracionamento das proteínas foi realizado por eletroforese em fita de acetato de celulose e em gel de poliacrilamida, contendo dodecil sulfato de sódio (SDS-PAGE), nas quais se avaliou o comportamento de 19 bandas proteicas identificadas pelos respectivos pesos moleculares, que variaram entre 23KDa e 187KDa. Não houve influência da RP na proteína... |

| Cotyledon explants were first cultured on MS medium supplemented with 4.52 M 2,4-D and 0.46 mM kinetin. The development of the calli was followed (0, 4, 8, 12, 16, 20, 24, 28 and 32 days after) and the growth curve was determined, based in fresh and dry weight. The growth curve presented sigmoidal form with four distinct phases. The highest growth percentage was observed at the exponential phase and the lowest at the stationary phase. These results indicated that cotyledon callus subculture should be performed 20 days after inoculation. The calli obtained after a period of 28 days were freeze dried, macerated and submitted to extraction with buffers of different pH values (2.6; 4.0; 6.0; 8.0 and 10.0) and the proteins in the extracts were determined by... |
