Provedor de dados: 69
Autores: Yuzbasioglu,Ertugrul; Dadandi,Mehmet Yasar.
This study used randomly amplified polymorphic DNA markers to determine genetic relationships among species of the subsection Dendrophlomis. Twenty accessions of the eleven Phlomis taxa were evaluated to determine genetic variability using fourteen ten mer primers selected from a 125 random oligonucleotide set. These 14 selected primers generated 85 RAPD bands that ranged in size from 200 to 1200 base pairs. Of the total bands, 88% (75) were polymorphic among the samples. Genetic distances among accessions were computed to produce a dendrogram based on UPGMA. Genetic distances ranged from 0.133 (between P. amanica and P. monocephala) to 0.494 (between P. chimerae and P. lunariifolia). The UPGMA tree based on distances has two major groups. The first...

Autores: Usme-Romero,Solangy; Alonso,Milena; Hernandez-Cuervo,Helena; Yunis,Emilio J.; Yunis,Juan J.
We analyzed the frequency of four mitochondrial DNA haplogroups in 424 individuals from 21 Colombian Amerindian tribes. Our results showed a high degree of mtDNA diversity and genetic heterogeneity. Frequencies of mtDNA haplogroups A and C were high in the majority of populations studied. The distribution of these four mtDNA haplogroups from Amerindian populations was different in the northern region of the country compared to those in the south. Haplogroup A was more frequently found among Amerindian tribes in northern Colombia, while haplogroup D was more frequent among tribes in the south. Haplogroups A, C and D have clinal tendencies in Colombia and South America in general. Populations belonging to the Chibcha linguistic family of Colombia and other...

Autores: Oliveira,Joelliton Domingos de; Igarashi,Maria Luiza Silveira de Paiva; Machado,Théa Mírian Medeiros; Miretti,Marcos Mateo; Ferro,Jesus Aparecido; Contel,Eucleia Primo Betioli.
The genetic relationships and structure of fourteen goat (Capra hircus) populations were estimated based on genotyping data from 14 goat populations (n = 410 goats) at 13 microsatellite loci. We used analysis of molecular variance (AMOVA), principal component analysis (PCA) and F statistics (F IS, F IT and F ST) to evaluate the genetic diversity (Ho, He and ad) of the goats. Genetic distances between the 14 goat populations were calculated from allelic frequency data for the 13 microsatellite markers. Moderate differentiation was observed for the populations of the undefined breeds (including the Anglo-Nubian-M breed), the naturalized Brazilian breeds (Moxotó, Canindé), the exotic purebred breeds (Alpine, Saanen, Toggenbourg and Anglo-Nubian) and the...

Provedor de dados: 74
Autores: Kusza,Szilvia; Dimov,Doytcho; Nagy,István; Bõsze,Zsuzsanna; Jávor,András; Kukovics,Sándor.
Herein, genetic relationships among five breeds of Bulgarian sheep were estimated using microsatellite markers. The total number of alleles identified was 226 at the 16 loci examined. D A distance values were used for phylogenetic tree construction with the UPGMA algorithm. The two Tsigai and two Maritza populations were found to be geneticallvery closely related to each other y (0.198, and 0.258 respectively). The Pleven Black Head population was distinct from the other four. These results could be useful for preserving genes in these breeds, thereby ensuring their preservation in Bulgaria.

Analysis of the genetic relationships from different genetic systems between the amylose content and the appearance quality of indica rice across environments
Provedor de dados: 74
Autores: Ge,Guo-Ke; Shi,Chun-Hai; Wu,Jian-Guo; Ye,Zi-Hong.
The genetic relationships between amylose content (AC) and appearance quality traits of indica rice (Oryza sativa L.) were investigated using conditional analysis and unconditional analysis in present experiment. The results from the unconditional analysis indicated that AC of rice positively correlated with brown rice (BR, i.e., dehulled but unmilled rice) length (BRL), width (BRW) and thickness (BRT), but was negatively correlated with the ratio of length to width (RLW). The conditional analysis showed that weight of brown rice (WBR) negatively affected the genetic relationships between AC and the appearance quality traits of rice except between AC and BRW, while the genetic relationships between AC and most appearance quality traits were negatively...

Autores: Martínez Marrero,Nadia; da Silva,Elizabete Cristina; Mitat Valdés,Alina; Ponce,Giselle; Benício da Silva,Regina C.; Paes Barbosa,Severino Benone; Uffo Reinosa,Odalys; Gomes Filho,Manoel Adrião.
Researches on genetic relationships among water buffalo populations are useful in supporting conservation decisions and designing of breeding schemes. The aim of this study was to assess the genetic relationships among Cuban Buffalypso/Carabao hybrids and Murrah and Jaffarabadi Brazilian buffaloes using nine cattle microsatellite markers. During the analysis, four loci were excluded due to the presence of null alleles, stuttering and gametic disequilibrium. Mean numbers of alleles and the heterozygosities observed and expected in the three populations were not significantly different. Heterozygosities found were above 60%. All five loci were in Hardy-Weinberg equilibrium. Wright´s index for estimating inbreeding were negative in the three populations. A...

Genetic similarity among Tunisian cultivated olive estimated through SSR markers
Provedor de dados: 63
Autores: Abdelhamid,Sofiane; Grati-kamoun,Naziha; Marra,Francesco; Caruso,Tiziano.
Olive (Olea europaea L. subsp. europaea var. europaea) is one of the oldest fruit tree in the Mediterranean basin, and is cultivated for oil and canned fruit. Part of this interest is driven by the economic importance of olive oil which is increasing throughout the world due to its beneficial effect to human health. In Tunisia, olive has great socio-economic importance, with more than 60 millions olive trees cultivated for olive oil production including a wide range of cultivars which are widely extended from the north to the south regions of the country for its high economic value. Here, we applied microsatellites (SSRs) molecular markers to assess the genetic variability of the most important Tunisian olive cultivars. In total, the 10 simple sequence...

GENETIC STATUS, SOURCE AND ESTABLISHMENT RISK OF THE GIANT TIGER SHRIMP (PENAEIDAE: Penaeus monodon), AN INVASIVE SPECIES IN COLOMBIAN CARIBBEAN WATERS
Provedor de dados: 37
Autores: AGUIRRE-PABÓN,J.C; OROZCO BERDUGO,G. Jr; NARVÁEZ BARANDICA,J.C.
The tiger shrimp (Penaeus monodon) is an Indo-Pacific species. Its global production between 1970 and 1980 exceeded all other shrimp species, which favored its introduction and cultivation outside its natural range in several countries of Africa, Europe, USA and South America. It is currently found in the coast of the Atlantic Ocean (Mexico, United States, Puerto Rico, Brazil, Guyana, Venezuela and Colombia). Despite the risk involved, no studies have been conducted to evaluate their impact as a possible invasive species and their genetic condition. This study evaluated the genetic status and population origin of P. monodon in the northernmost Colombian Caribbean, analyzing the mitochondrial DNA control region (mtDNA-CR). 16 individuals were randomly...

Autores: Gálvez-López,Didiana; Salvador-Figueroa,Miguel; Becerra-Leor,Enrique N.; González-Paz,Maurilio; Hernández-Delgado,Sanjuana; Mayek-Pérez,Netzahualcóyotl.
Most of mango (Mangifera indica L.) production in Chiapas, México is located at Soconusco region where a large morphological and genetic diversity have been detected due the free-pollination among plants. The characterization and identification of outstanding plants can be useful for mango diversity conservation as well as the use for mango breeding. Forty-one local mango accessions collected in five locations (Huehuetán, Pijijiapan, Tuxtla Chico, Tapachula, Escuintla) in the state of Chiapas, México, were subjected to AFLP analysis and then compared with 19 mango cultivars. AFLP analysis indicated high levels of polymorphisms among accessions (&gt; 84 %). AMOVA analysis indicated significant genetic differentiation (F ST = 0.23743) among and within mango...

Provedor de dados: 65
Autores: Tagliaro,Cláudia Helena; Franco,Maria Helena Lartigau Pereira; Schneider,Maria Paula Cruz; Brito,Benito Guimarães de; Barbosa,Antonio Stockler.
The genetic variability of 14 protein systems encoded by 15 structural loci was investigated in blood samples of Piau and Caruncho pig breeds. The results were compared with those obtained previously for samples of Landrace, Large White, Duroc and Mouro. The degree of genetic variability obtained for Piau (He=0.114) was similar to that estimated for other breeds reared in Brazil (Landrace, He=0.116; Large White, He=0.119; Duroc, 0.095; Mouro, He= 0.130). Caruncho showed the lowest variability (He= 0.056). The gene frequencies at the polymorphic loci were used to evaluate the usefulness of these systems for paternity testing and the combined probabilities of paternity exclusion were estimated at 58% for the Piau and 36% for the Caruncho breed. Analysis of...

Provedor de dados: 65
Autores: Tagliaro,Cláudia Helena; Franco,Maria Helena Lartigau Pereira; Weimer,Tania Azevedo.
The data of three protein polymorphisms were used to investigate the genetic relationships among the Landrace, Large White and Duroc swine breeds reared in Brazil, 12 other populations of these same breeds from various countries and a population of Belgium Landrace. The dendrogram, constructed from matrix of genetic distance coefficients, disclosed three large groups clustered by breed. Among them, the Landrace and the Large White showed in average closer resemblance (D= 0.203) than between them and Duroc (D= 0.241). It the three breeds, the smallest genetic distances were found between Brazilian and Cuban pig populations (Landrace: D = 0.060; Large White: D = 0.052; Duroc: D = 0.065), although there were not reports of pig exchanges between these two...
