Black Sigatoka; Genetic diversity; Molecular markers; Population genetics; VNTRs

We searched the genome of Mycosphaerella fijiensis for molecular markers that would allow population genetics analysis of this plant pathogen. M. fijiensis, the causal agent of banana leaf streak disease, also known as black Sigatoka, is the most devastating pathogen attacking bananas (Musa spp). Recently, the entire genome sequence of M. fijiensis ... more

Dalbergia sissoo Roxb.; Genetic differentiation; Genetic diversity; RAPD

Dalbergia sissoo, a wind-dispersed tropical tree, is one of the most preferred timber tree species of South Asia. Genetic diversity and differentiation among natural populations of D. sissoo were examined for the first time. We found a relatively high level of genetic diversity in D. sissoo, both at the species level (percentage of polymorphic bands = 89.11%; H ... more

C. equisetifolia subsp incana; Casuarina equisetifolia subsp equisetifolia; Genetic diversity; Molecular marker; Northern coast of Senegal; RAPD

The genetic variation of 70 individual samples of Ca­suarina equisetifolia (L. Johnson) subsp equisetifolia and C. equiseti­folia subsp incana growing along the northern coast of Senegal was analyzed with RAPD markers. Of the 160 primers tested, five were chosen; they generated 1396 reproducible bands and 61 polymorphic bands that were scored. This ... more

Diatraea saccharalis; Genetic diversity; RAPD; Sex-specific marker

Diatraea saccharalis is an insect that causes considerable losses in the sugar cane crop. Our aim was to contribute to the knowledge of the biology of D. saccharalis, with the report of DNA fragments involved in the differentiation between the male and female of this species using the RAPD sex molecular marker GyakuU-13, which is specific for the W chromosome of ... more

Genetic diversity; Population structure; Portunus pelagicus; RAPD; Species-specific markers

Genetic diversity and population differentiation of the blue swimming crab, Portunus pelagicus, in Thailand were analyzed by RAPD analysis. One hundred and twelve RAPD fragments were generated from 109 individuals of P. pelagicus using OPA02, OPA14, OPB10, UBC122, and UBC158 primers. The percentage of polymorphic bands in each geographic sample and that of each primer ... more

Brassica rapa var. rapa; Genetic diversity; RAPD; Turnip

Turnip (Brassica rapa var. rapa) is one of the main vegetables consumed by people living in Eastern Anatolia in Turkey. In this region, farmers obtain their own seeds for production, which results in considerable morphological variability. We examined the genetic variation and relationships among 11 turnip genotypes sampled from diverse environments of the Erzurum region ... more

Diospyros lotus; Genetic diversity; Persimmon; RAPD

Turkey is one of the most important genetic resources of the date plum, Diospyros lotus, especially in the northeastern part of the country. Authenticating the identity of germplasm resources of D. lotus would be of great value for breeding. We examined the genetic variability of 11 D. lotus genotypes sampled from Coruh Valley in Turkey. One hundred and twenty- ... more

Genetic diversity; Local adaptation; Parapiptadenia rigida; RAPD; Submergence; Waterlogging

The tree species Parapiptadenia rigida, native to southern South America, is frequently used in reforestation of riverbanks in Brazil. This tree is also a source of gums, tannins and essential oils, and it has some medicinal uses. We investigated flooding tolerance and genetic diversity in two populations of P. rigida; one of them was naturally exposed to flooding. ... more

Biofuels; Fodder; Genetic diversity; RAPD; Sorghum bicolor

Sorghum ranks fifth in worldwide economic importance among cereal crops and is one of the most important summer annual grasses of Pakistan. As it is a very diverse crop, sorghum genetic fingerprinting requires an efficient marker system. We estimated genetic divergence among 29 sorghum (Sorghum bicolor) genotypes, including approved varieties and local and exotic lines collected ... more

Electrophoretograms; Genetic diversity; Microsatellites; Molecular markers; Stutter peaks

Microsatellite markers are commonly used for examining population structure, especially inbreeding, outbreeding and gene flow. An array of microsatellite loci, preferably with multiallelic presentation, is preferable for ensuring accurate results. However, artifact peaks or stutters in the electrophoretograms significantly hamper the reliable interpretation of genotypes. We interpreted ... more
