Evaluation of Genetic Diversity and Stability of Colocasia Cultivars Using ISSR
… produced from Inter-simple sequence repeat (ISSR) markers. Comparing banding patterns of vegetatively propagated clones of each cultivar, genetic stability was examined. Unweighted pair group method with arithmetic mean (UPGMA) and principal coordinate analysis (PCO) were performed to examine …

Investigation into the use of molecular methods to distinguish between species of Caladenia subgenus Calonema
… The analyses were performed using 17 RAPD and 10 ISSR primers on 30 taxa representing the three spider orchid groups (the dilatata, patersonii and reticulata groups) yielding 135 RAPD and 63 ISSR polymorphic markers. The average number of polymorphic markers produced from 17 RAPD and 10 ISSR …

In Vitro Kavapyrone Production and Genomic Stability of in Vitro Kava Cultures
Inter simple sequence repeat (ISSR) markers were used for detection of polymorphism among in vitro kava cultures. An absence of normally observed bands was observed among organogenic callus cultures, while a small degree of ISSR polymorphism was detected among regenerated plantlets.

Molecular markers for the assessment of genetic variability in threatened plant species
… arbitrari RAPD e i marcatori semi-arbitrari ISSR sono stati utilizzati per valutare la diversità genetica in Quercus crenata Lam. e per confermare l’ipotesi della sua origine ibridogena dalle due specie presunte parentali Quercus cerris L. e Quercus suber L., essendo Q. crenata presente in …

An alternative hypothesis for explaining anomalies in the fine scale distribution patterns of Colophospermum mopane : Are shrub and tree forms genetically distinct ?
… region, and the inter simple sequence repeat (ISSR) technique used to fingerprint individuals. Very low levels of sequence divergence were observed. The ISSR technique revealed no genetic structure between plants when grouped by growth form or by habitat in an analysis of molecular variance …

Filogeografia, diferenciação geográfica e caracterização citogenética de populações naturais de Psychotria ipecacuanha das florestas Atlântica e Amazônica
… basead em cpDNA, estrutura de população via ISSR, e citogenética para caracterizar populações naturais de poaia das florestas Atlântica e Amazônica do Brasil. As análises permitiram elaborar e avaliar hipóteses dos fatores históricos e ecológicos que moldaram a atual distribuição das …

Nymphaea odorata (Water-lily, Nymphaeaceae): Analyses of molecular and morphological studies
… trnL-F region, and inter-simple sequence repeat (ISSR) markers determined the variation present between and within two species of Nymphaea. The ITS region resulted in a phylogeny depicting strong separation between species (N. mexicana and N. odorata) and some separation between N. odorata's …

Evolution in the genus Arum: a comparative analysis of morpohological and genetic variation.
… zone. At the intraspecific level, genetic (ISSR) and morphological variation was quantified in populations of the morphologically similar species A. maculatum and A. italicum. Populations of A. maculatum showed evidence of isolation by distance, presumably a result of pollinator behaviour …

Population Genetics and Differential Pathogenicity of the Soybean Brown Stem Rot Pathogen Phialophora Gregata
… (amplified fragments length polymorphism) and ISSR (inter simple sequence repeat) analyses were used to detect genetic diversity in Phialophora gregata. Various levels of DNA polymorphism were detected among the 45 soybean and mung bean isolates of P. gregata . Generally the estimated average …

Phylogeography of Marine Meiofaunal Nemerteans of the Ototyphlonemertes Fila Species Complex
… using mitochondrial (cox3) and nuclear (ISSR) molecular markers. Deep genetic divergence (approximately 18% in cox3) was observed between sympatric mitochondrial lineages in Florida. This divergence was reflected in the nuclear marker as well, suggesting the presence of two cryptic …

Morphological and molecular analyses for the characterization of Aspalanthus linearis (Fabaceae: rooibos)
… based methods: inter-simple sequence repeats (ISSR) and a plastid marker. A principle component analysis (PCA) based on seven morphological variables grouped the samples into three different growth forms, specifically an erect-form, a prostrate-form and a shrub-form. The genetic variability of …

Genetic and morphological means of differentiating within and between populations of Widdringtonia whytei and Widdringtonia nodiflora on Mount Mulanje, Malawi
… DNA), ITS (nuclear DNA), microsatellite and ISSR gene region markers. Out of the markers that amplified successfully, it was found that there is little genetic variation present with no differentiation between or within taxonomic groups for the gene regions analyzed. Morphometric analysis of …

Meccanismi fisiologico-molecolari di germinazione in specie spontanee
… using Inter Simple Sequence Repeat (ISSR) PCR together with a DNA-Barcoding approach. Seed priming treatments were used in a non-dormant species, Leucanthemum vulgare, to induct secondary dormancy at specific temperature range and a long-priming treatment was used for its release. …

Molecular diversity of Primula apennina and phylogeny of Primula Subsection Euauricula
… is endemic to the North Apennines (Italy). ISSR were used to detect the genetic diversity within and among six populations representative of the species distribution range. High levels of genetic diversity were revealed both at population (PPB = 75.92%, HS = 0.204, Hpop = 0.319) and at …

The Role of Temperature in the Seed Germination Ecology of Mountain Springs and Fens
… perform a common garden experiment supported by ISSR fingerprinting to determine the genetic and environmental influences on seed dormancy variation. Based on our results, we propose two germination strategies. Fen species generally follow a warm strategy, characterized by a heat response capable …
