Molecular Characterization of Saccharomyces cereviceae using RAPD Molecular Markers
Yeasts are eukaryotic microorganisms including 1,500 species. They are an important model organism in modern cell biology research, and are one of the most thoroughly researched eukaryotic microorganisms. Some yeast can find potential application in the field of bioremediation. In the present investigation the yeast samples were isolated on YPD medium from natural sources like ripened fruits, m...
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 کاملMolecular characterization of cajá, Spondias mombin (Anacardiaceae), by RAPD markers.
The arboreal species Spondias mombin L. (Anacardiaceae) is widely distributed in Brazil, where the fruits, known by the common name of cajá, are an important commercial commodity. We evaluated genetic variability among 32 cajá accessions of the Germplasm Collection of Embrapa Meio-Norte using RAPD technique. Reaction conditions for efficient RAPD amplifications were optimized in prelimina...
متن کاملGenetic Divergence among Elephantgrass Cultivars Assessed by Rapd Markers in Composit Samples
Elephantgrass (Pennisetum purpureum Schum.) is native to regions of tropical Africa and was introduced in Brazil around 1920 through plantings imported from Cuba. It is currently one of the most widespread forage plants throughout the country. At first, there were two cultivars, Napier and Mercker, with well defined characteristics. New genotypes arose and it is believed that the large number o...
متن کاملMolecular Characterization of Unknown Potentially Salt Tolerant Olive Genotypes Using RAPD Markers
Randomly amplified polymorphic DNA (RAPD) markers were used to study the genetic diversity and discriminate among 17 unknown genotypes (considered potentially salt tolerant) and 16 known olive cultivars. Fifteen decamer primers which produced 38 reproducible polymorphic bands in the genotypes were selected for analysis. The RAPD markers resulted in 93 distinct banding patterns. Based on either ...
