Cannabis sativa L. is a multiple-use plant that provides raw material for the production of seed oil, natural fiber for textiles, automotive and pulp industries. It has also been used in insulating boards, ropes, varnishes, animal feed, and as medicinal agents. Cannabis has potential to be used for phytoremediation: however, its cultivation is strictly controlled due to its psychoactive nature and usage in producing drugs such as marijuana, and hashish. In this study, psychoactive type Cannabis samples, which were seized from 23 different locations of Turkey, and nine hemp type Cannabis accessions, as well as an unknown accession were used. Our interest was to identify the genetic relatedness of the seized samples and to separate drug and hemp type plants.... |

Background Genetic diversity and genetic variation of 10 populations and subpopulations of Magnolia wufengensis, a new and endangered endemic species, were examined by inter simple sequence repeat (ISSR) and sequence-related amplified polymorphism (SRAP) molecular markers. Compared with other endangered endemic Magnolia taxa, M. wufengensis holds a relatively high level of genetic variation. Result Total genetic diversity was found to be 87.7% for ISSR and 88.0% for SRAP markers. For polymorphic loci (P), the effective mean number of alleles (Ae) was 1.414 for ISSR markers and 1.458 for SRAP markers, while the mean expected heterozygosity (H) was 0.256 using ISSR and 0.291 for SRAP markers. Within-population variation was estimated for P as 74.9% using... |

The objective of the present work was to establish the molecular identification profile for six new varieties of Nierembergia linariaefolia to incorporate the fingerprint, as complementary information to the standard registration data. Total DNA was extracted from young leaves following the protocol of the cetyltrimethylammonium bromide. Anchored microsatellites were used as molecular markers. The amplification reactions were carried out with seven primers. A total of 251 loci were detected, 98% of them were polymorphic. The average of polymorphic loci was 35 loci per primer and, 41 loci per genotype. Six out of the seven primers used discriminated all the individuals involved in the present study; consequently, it was possible to generate the molecular... |

To examine whether cultivation reduced genetic variation in the important Chinese medicinal plant Rheum tanguticum, the levels and distribution of genetic variation were investigated using ISSR markers. Fifty-eight R. tanguticum individuals from five cultivated populations were studied. Thirteen primers were used and a total of 320 DNA bands were scored. High levels of genetic diversity were detected in cultivated R. tanguticum (PPB = 82.19, H = 0.2498, H B = 0.3231, I = 0.3812) and could be explained by the outcrossing system, as well as long-lived and human-mediated seed exchanges. Analysis of molecular variance (AMOVA) showed that more genetic variation was found within populations (76.1%) than among them (23.9%). This was supported by the coefficient... |

En muchos países, el tomate (Solanum lycopersicum L.) es la especie hortícola más importante, pero la semilla de variedades sobresalientes es cara. En el mejoramiento genético mediante hibridación, el número de cruzas simples posibles es demasiado alto con pocas líneas. Por ejemplo, con 60 líneas el número de híbridos posibles es 1770. Esto hace inaccesible (en términos de costos), y aún imposible efectuar una evaluación experimental adecuada. Situaciones como ésta generan la necesidad de disponer de métodos de predicción del rendimiento de fruto de los híbridos. Este estudio se desarrolló para evaluar un método de predicción del rendimiento de fruto de híbridos basado en huellas genómicas, teoría de los modelos mixtos y en la evaluación experimental de... |

Abstract This study aimed to estimate the genetic diversity of three Elaeis guineensis populations in Rio Grande do Norte state, as well as to verify the decreases in effective population size. The population with the highest polymorphism was MAT (Mata) with+ 57 loci (72%), followed by RIA (Riacho) with 54 loci (68%) and HOR (Horta) with 34 loci (43.03%). The RIA population was shown to be the most genetically diverse, with Nei (h = 0.28) and Shannon (I = 0.41) diversity indices. There was high genetic differentiation among populations (AMOVA, analysis of molecular variance = 42%), which was separated into three distinct genetic groups according to a Bayesian analysis. There was a significant population decrease (P < 0.05) for the HOR population in the... |

Determinou-se a variabilidade genética de 37 isolados de Fusarium solani e 13 isolados de Fusarium oxysporum f. sp. passiflorae patogênicos ao maracujazeiro por meio do uso de marcadores ISSR e RAPD. Os isolados foram obtidos de maracujazeiros com sintomas de murcha, encontrados nas principais regiões produtoras do Norte Mineiro e no município de Sebastião Laranjeira – BA. Após obtenção de culturas monospóricas, os isolados tiveram seus DNAs extraídos e submetidos à reação de PCR. Foram selecionados nove primers ISSR e nove primersRAPD, e a análise de dados foi realizada, utilizando-se do coeficiente de similaridade de Jaccard. A partir da amplificação com os primers ISSR e RAPD, foram obtidos 121 e 126 locos, respectivamente, sendo quetodos apresentaram... |

The radish has been gaining importance in the Brazilian market due to its use as a green manure and cover crop, and also due to its potential for the production of biodiesel, however there are only two registered cultivars, which are morphologically very similar. Determination of genetic purity is a prerequisite in marketing seeds as it ensures uniformity of the crop and is important in breeding programs. The aim of this work therefore was to evaluate the similarity and genotype patterns which permit differentiation of the commercial radish cultivars IPR 116 and CATI AL-1000. In order to do this, isoenzyme electrophoretic patterns were analysed in dry seeds, soaked seeds, seedling leaves and young leaves; the isoenzymes used being: superoxide dismutase,... |

ABSTRACT Although a species’ sexual system may influence the genetic diversity of its populations in their natural environment, there have been few such studies involving indigenous species of the Atlantic Forest. Here we study Myrsine coriacea, a dioecious tree widely used in reforestation programs despite a lack of information about its natural interpopulation genetic variation. To address this knowledge gap, intra- and interpopulation genetic diversity were measured for male and female individuals of ten natural populations using ISSR markers. Greater intrapopulation genetic diversity indicated interpopulation gene flow, regardless of isolation and distance between populations. Multivariate analyses detected significant differences in genetic diversity... |

Random amplified polymorphic DNA (RAPD), Inter simple sequence repeat (ISSR) and Amplified fragment length polymorphism (AFLP) markers were used to verify the segregation of the genus Cassia L. senso lato into three distinct genera namely Chamaecrista Moench., Senna P. Mill. and Cassia L. sensostricto Eighteen representatives of the three taxa were characterized using the molecular markers. 25 RAPD, six ISSR primers and six AFLP primer combinations resulted in the amplification of 612, 115 and 622 bands (loci) respectively. Most of the loci are found to be polymorphic, showing high degrees of genetic diversity among the different taxa studied. The dendrogram constructed on the basis of the RAPD, ISSR and AFLP data using SHAN clustering, divided Cassia L.... |
