The family Passifloraceae consists of some 700 species classified in around 16 genera. Almost all its members belong to the genus Passiflora. In Brazil, yellow passion fruit (Passiflora edulis) is considerable economic importance, both for juice production and consumption as fresh fruit. availability chloroplast genomes (cp genomes) their sequence comparisons has led a better understanding evolutionary relationships within plant taxa. this study, we obtained complete nucleotide Passiflora...

A new method is proposed for the extraction of morphometric characteristics plant leaf structures. sample 10 species genus Passiflora (P. coriacea Juss., P. foetida L., miersii Mast., organensis Gardner, pohlii suberosa amethystina J.C. Mikan, caerulea gibertii N.E.Br., maliformis L.) was used in an experiment to test method. This shows a wide range forms, but there are some pairs or groups whose morphological similarity makes their correct identification difficult. The multiscale function...

Methods Four from South America, Oryza glumaepatula, O. latifolia, grandiglumis alta, sativa cultivars were tested one experiment. In a second experiment, five species, punctata, eichingeri, O.rufipogon, latifolia (O. glaberrima) evaluated. Initial...

Abstract One of the most intriguing questions in plant ecology is which evolutionary strategy allows widely distributed species to increase their ecological range and grow changing environmental conditions. Phenotypic plasticity local adaptations are major processes governing margins, but little known about relative contribution for tree distribution tropical forest regions. We investigated role phenotypic adaptation widespread palm Euterpe edulis Brazilian Atlantic Forest. Genetic sampling...

To characterize the genetic variability among species and populations of South American wild rice, eleven Oryza glumaepatula, seven O. grandiglumis, four latifolia one alta, from Brazil Argentina, were evaluated. A greenhouse experiment was conducted in completely randomized blocks with 23 treatments. Twenty morphoagronomic traits assessed. Univariate analyses performed 16 quantitative partitioning within species. Significant differences (p<0.001) between observed for all as well The most...

Knowledge of the genetic structure and diversity natural populations is important in developing strategies for situ ex conservation. We used eight microsatellite loci to estimate investigate within between population variation eleven Brazilian wild rice (Oryza glumaepatula) populations. The study showed following parameters: average number 3.1 alleles per locus; 77.3% polymorphic loci; 0.091 observed heterozygosity 0.393 gene diversity. F-statistics detected by were: F ST = 0.491 (and R...

Xenia, the transmission of traits from pollinizer to female's tissues, is a phenomenon hitherto unknown in tomatoes. Here, we describe xenia effects on seeds and fruits Solanum lycopersicum, tomato, elicited by S. galapagense. The wild tomatoes, such as galapagense, have highly pilose fruit surface minute seeds, unlike domesticated species. Crossings between galapagense (pollinizer) two large-seeded, glabrous cultivars lycopersicum (females) tested former's ability raise trichome density...

The GxE interaction only became widely discussed from evolutionary studies and evaluations of the causes behavioral changes species cultivated in environments. In last 60 years, several methodologies for study adaptability stability genotypes multiple environments trials were developed order to assist breeder's choice regarding which are more stable most suitable crops diverse methods that use linear regression analysis first be used a general way by breeders, followed multivariate mixed...

Abstract Passiflora alata is one of the commercialized species passion vines, grown for its edible fruits. It found in South America, mainly Paraguay, Argentina, Peru and Brazil. The development a set microsatellite markers was proposed to provide tools analysing both genetic structure wild populations reproductive system species, which are poorly understood. Seven were developed from P. ‐genomic library enriched simple sequence repeats (SSR). Twelve individuals genotyped, levels expected...

Background and Aims A knowledge of natural populations' breeding systems is important in order to implement situ ex management conservation practices. Using microsatellite markers, three Oryza glumaepatula populations from Brazil were studied determine the system genetic structure parameters this species.

El estudio de la estructura genética poblaciones plantas silvestres es esencial para su manejo y conser- vación. Varios marcadores ADN e isoenzimas se han utilizado en este tipo análisis. Con el fin proporcionar una mejor comprensión los resultados obtenidos saber que marcador codominante elegir futuros estudios naturales Oryza glumaepatula, trabajo busco evaluar comparar dos ADN, microsatélites, diversidad 13 poblaciones, destacando las similitudes divergencias cada marcador, así como...

The commercial release of genetically modified organisms requires the prior environmental and human/animal health risk assessment. In Brazil, National Biosafety Authority (CTNBio) demands to survey area natural occurrence wild relatives GMO in Brazilian ecosystems evaluate possibility introgressive hybridization between sexually compatible species. Modern sugarcane cultivars, focus this study, derive from a series backcrossing events among Saccharum so-called "Saccharum broad sense" includes...

Microsatellite markers were developed for the endangered Brazilian orchid species Cattleya coccinea to describe its genetic diversity and structure support conservation studies.Nine microsatellite loci isolated characterized using an enriched genomic library.All are polymorphic at least in 2 populations sampled, except Cac05 Cac09 Petrópolis population.The mean number of alleles per locus was 8.8 between populations.The values observed expected heterozygosities 0.541 (ranging from 0 1) 0.639...

This study aimed to compare the genetic diversity of populations Solanum lycocarpum A.St.-Hil between natural and human disturbed environments, with assumption that protected areas have greater than areas. For this study, two were sampled in Goiás State, Brazil. One was located a conservation unit, Serra de Caldas Novas State Park, municipality. The other pasture area municipality Morrinhos. are 41 km apart. We 60 individuals from each population, which genotyped five microsatellite loci...

Several methods have been proposed to measure effects of genotype × environment interaction (G×E) on various traits interest plant species, such as grain yield.Among these methods, mixed models using the Restricted Maximum Likelihood (REML)-Best Linear Unbiased Prediction (BLUP) procedure with random reported advantageous, since they allow obtaining actual genotypic values for cultivation and use.The objective this work was evaluate response yield different locations years, G×E performance...
