Última Characterization and discrimination of three Rhopalosiphum species (Homoptera: Aphididae) based on isozymes Zoologia Lázzari,Sonia M. N.. Seventeen clones of Rhopalosiphum padi (Linnaeus, 1758), 14 of R. maidis (Fitch, 1856), and two of R. insertum (Walker, 1849), representing a wide range of host plants and geographic distribution, were examined electrophoretically to determine intra and interspecific variation. Twenty-one enzyme systems were tested using starch-gel techniques. The electromorph variation within species was low, as expected for parthenogenetic organisms. Frequency of heterozygotes was also relatively low for most populations. The percentage of polymorphic loci ranged from 0% to 27.3% in R. padi, but it was lower (0% to 18.2%) in the completely an holocyclic R. maidis. No consistent correlation between band patterns and host plant or geographic origin could be established for...

Of eleven proteins analyzed in four Amazonian populations, the esterases showed the greatest variation, with five activity zones. EST1, EST2 and EST5 showed variation in each of the populations studied. EST1 and EST2 are each controlled by two, and EST5 by four, codomi-nant alleles. LAP presented six activity zones, with codominant variation in LAP5and LAP6.oc—GPDH was monomorphic with one activity band on starch gel and two on polyacrylamide gel. 1DH presented two activity zones, with variation in the IDHl region. PGM had a single activity zone, with variation in all populations. The Ariquemes populations showed five alleles and the other populations three, all of then codominant. Three activity zones with two codominant alleles were observed for ODH.... Tipo: Info:eu-repo/semantics/article Palavras-chave: Anopheles darlingi; Isozymes; Electrophoresis.

Bras. Fisiol. Veg. ENÉAS-FILHO,JOAQUIM; BARBOSA,GISLAINY KARLA DA COSTA; SUDÉRIO,FABRÍCIO BONFIM; PRISCO,JOSÉ TARQUÍNIO; GOMES-FILHO,ENÉAS. Three isoforms of beta-galactosidases were isolated and partially purified from the cotyledons of quiescent seeds of Vita 3 and Vita 5 cowpea [Vigna unguiculata (L.) Walp.] cultivars differing in water and salt stress tolerance. The purification procedure consisted of ammonium sulfate fractionation, acid precipitation, ion exchange chromatography through DEAE-sephadex and affinity chromatography through Lactosyl-sepharose columns. The three isoforms isolated from the two cultivars showed the same chromatographic patterns, same optimum of temperature for enzyme activity assay (60ºC), identical thermal stability up to 50°C, and similar pH optima (3-4). However, they differed from each other in sensitivity towards metal ions and certain chemical agents...

Biol. Ruvolo-Takasusuki,Maria Claudia C.; Machado,Maria de Fátima P.S.; Conte,Hélio. The migration rate of esterases and their substrate specificity for 4-methylumbelliferyl esters (acetate, propionate, and butyrate) and alpha- and beta-naphthyl esters were analyzed in Diatraea saccharalis by starch gel electrophoresis. Substrate preference of esterases was observed with Est-2 and Est-8 isozymes showing substrate specificity for 4-methylumbelliferyl esters and Est-4 isozyme showing specificity for 4-methylumbelliferyl butyrate and alpha-naphthyl butyrate. Allele variation was detected at the Est-3 locus. Two alleles, Est-3F and Est-3S, were identified in pupae with fluorogenic and ester-naphthyl substrates. Chi-square analysis showed no differences between the observed genotypic frequencies and those expected on the basis of Hardy-Weinberg...

Cassava (Manihot esculenta Crantz) belongs to the Euphorbiaceae family, and is widely cultivated in Brazil. The objective of this study was to evaluate the isoenzymatic variability of 200 cassava accessions from the germplasm bank of Embrapa Amazonia Oriental. Seven groups were formed according to their origin: 1-Amazonas, 2-Amapa, 3-Bahia, 4-Para, 5-Rondonia, 6-Various, for accessions with a maximum of three individuals per place of origin, and 7 - Accessions of indefinite origin. The accessions were also evaluated as a whole. For the electrophoretic analyses, samples of young leaves were used in a 12% starch gel. Eight isoenzymatic systems were evaluated: acid phosphatase (ACP), leucine aminopeptidase (LAP), glucose-6-phosphate dehydrogenase (G6PDH),...

Mol. Biol. Fraga,Elmary da Costa; Santos,Joselita Maria Mendes dos; Maia,Juracy de Freitas. Eighteen enzymatic loci were analysed in Aedes aegypti populations from four neighbourhoods in the city of Manaus. The analyses showed that the Downtown population was the most polymorphic (p = 55.6%) with higher observed and expected mean heterozygosities (Ho = 0.152 ± 0.052; He = 0.174 ± 0.052, respectively). The least variability was detected in the Coroado and Cidade Nova populations, both with polymorphism of 44.4%. The latter population presented the least observed heterozygosity (Ho = 0.109 ± 0.037). Wright's F statistics showed that the mean value of Fis was higher than that of Fst (Fis = 0.164 > Fst = 0.048), and from analysis of molecular variance (AMOVA) it was found that 95.12% of the variability is found within populations indicating a...

Mol. Biol. Scarpassa,Vera Margarete; Hamada,Neusa. Electrophoretic studies of isozymes were done with four closely related species of the Simulium perflavum species group (Diptera: Simuliidade) in the Brazilian Amazon, using last-instar larvae collected in the field. Ten enzymes were studied, which yielded 11 loci. Diagnostic loci were not found between Simulium maroniense cytotype D and Simulium rorotaense. Simulium maroniense and S. rorotaense differed from Simulium trombetense by two diagnostic loci (Me and Xdh), and Simulium perflavum differed from the other three species by four diagnostic loci (Me, Xdh, Mdh, and Got). The mean number of alleles per locus ranged from 1.30 to 2.30, the percentage of polymorphic loci ranged from 18.2 to 63.6% and the mean heterozygosity values observed ranged from 0.062...

Maize (Zea mays L.) is one of the crops in which the genetic variability has been extensively studied at isoenzymatic loci. The genetic variability of the maize populations BR-105 and BR-106, and the synthetics IG-3 and IG-4, obtained after one cycle of a high-intensity reciprocal recurrent selection (RRS), was investigated at seven isoenzymatic loci. A total of twenty alleles were identified, and most of the private alleles were found in the BR-106 population. One cycle of reciprocal recurrent selection (RRS) caused reductions of 12% in the number of alleles in both populations. Changes in allele frequencies were also observed between populations and synthetics, mainly for the Est 2 locus. Populations presented similar values for the number of alleles per...

Ribeiro,Renata Acácio; Lovato,Maria Bernadete. Senna multijuga is a pioneer tropical tree species that occurs mainly in the Brazilian Atlantic forest. We investigated the mating system of two populations of S. multijuga, one located in a reserve area (RD1) and the other (RD2) about 15 km away. The mating system parameters were estimated using the mixed mating model (software MLTR). The two populations had significantly different outcrossing rates, with population RD2 having a high rate (t m = 0.838) and population RD1, a lower rate (t m = 0.540). The values of t s were different between the two populations and also lower than those of t m. Significant t m - t s estimates indicated that biparental inbreeding contributed to the apparent selfing rate in these populations. The correlation of paternity was...

The objective of this work was to characterize 27 potato genotypes, using molecular markers. Polyacrylamide gel electrophoresis, RAPD techniques and isozymes of esterase, phosphoglucomutase and soluble proteins were analyzed in tubers, and isocitrate dehydrogenase, aspartate transaminase, phosphoglucomutase and peroxidase, in leaves. Eighteen primers were tested and four were chosen, kits OPX (01, 04 and 09) and OPY (07), to analyze RAPD markers in leaf extracts. Similarity and cluster analysis were conducted using Jaccard coefficient and the unweighted pair-group method using arithmetic average. Despite the differences detected in the analysis of proteins and isozymes in the tubers, as well as of isozymes in the leaves, the characterization of all...

S.. Esterase isozymes were used to detected substrate-preference polymorphism in twenty cultivars of Manihot esculenta, and to show cultivar-specific variation of this species. A relatively complex extraction solution of proteins from leaves was needed to show a larger number of esterase isozymes. Similarity between cultivars from six groups ranged from 51 to 96%. The cultivars identified by the same name seemed to be biochemically different regarding esterase isozymes. Esterase isozyme electrophoretic patterns could, therefore, be used to discriminate the cultivars identified by the same name, and to monitor the vegetative propagation of cultivars maintained in the germplasm collection. In breeding strategies, isoesterase analysis could be used to avoid...

Host-Pathogen specificity and resistance components Agrociencia Lozoya-Saldaña,Héctor; Guzmán-Galindo,Leonel; Fernández-Pavia,Sylvia; Grünwald,Niklaus J.; McElhinny,Elaine. Abstract The molecular identity of Phytophthora infestans strains infecting potatoes in the Toluca Valley has been documented. Nevertheless, the relationship of the P. infestans genotypes to the host’s genetic resistance is unclear. In order to identify potential host-pathogen specificity, isolates of the oomycete obtained from five potato varieties with differing levels of disease resistance were compared regarding mating type (MT), isozyme genotype for glucose-6-phosphate isomerase (Gpi) and peptidase (Pep), and sensitivity to metalaxyl. Also, host resistance components and specificity on the host-pathogen interaction were assessed twice in detached leaves in the laboratory and once in attached leaves in the greenhouse for three of the varieties.
