Characterization of 10 new nuclear microsatellite markers in Acca sellowiana (Myrtaceae)1
UNLABELLED PREMISE OF THE STUDY Microsatellite primers were identified and characterized in Acca sellowiana in order to expand the limited number of pre-existing polymorphic markers for use in population genetic studies for conservation, phylogeography, breeding, and domestication. • METHODS AND RESULTS A total of 10 polymorphic microsatellite primers were designed from clones obtained fro...
متن کاملIdenti®cation of Feijoa sellowiana Berg accessions by RAPD markers
Random ampli®ed polymorphic DNAs (RAPDs) were used to discriminate among 25 Feijoa sellowiana cultivars and accessions. Fifty ten-mer oligonucleotide primers were tested on ®ve accessions. Twenty-two primers, showing clear polymorphic patterns, were chosen to amplify the DNAs of all 25 genotypes; each ampli®cation was repeated three times separately. Only 11 primers were ®nally analysed, yieldi...
متن کاملPhytotoxic potential of young leaves from Blepharocalyx salicifolius (Kunth) O. Berg (Myrtaceae).
The loss of leaves by plant species found in the Cerrado (Brazilian savanna) is an energetically expensive process due to adverse environmental conditions and predation by herbivory. The mature leaves have adaptations which minimize these events. However, the young individuals lack these structures and produce high leaf concentrations of secondary metabolites as a form of protection. These comp...
متن کاملChemical composition and acetylcholinesterase inhibitory activity of essential oils of Myrceugenia myrcioides (Cambess.) O. Berg and Eugenia riedeliana O. Berg, Myrtaceae
The chemical composition of volatile oils from two Myrtaceae species, Myrceugenia myrcioides and Eugenia riedeliana, both native from the Brazilian Atlantic Rain Forest, was analyzed by GC-MS. Acetylcholinesterase inhibitory activity was colorimetrically evaluated for these oils. For M. myrcioides, monoterpene hydrocarbons represented the major class in the volatile oil, with α-pinene as the mo...
متن کاملIn Vitro Inhibitory Activity of Acca sellowiana Fruit Extract on End Products of Advanced Glycation
INTRODUCTION Hyperglycemia plays an important role in the pathogenesis of diabetic complications, as it increases protein glycation, as well as the progressive accumulation of advanced glycation end products (AGEs), which are complex structures that produce fluorescence. The glycation reaction raises the levels of protein carbonyl, N ε-(carboxymethyl)lysine (CML), and fructosamine and decreases...
