Anthropogenic impact; Genetic diversity; Mytilus galloprovincialis; Pollution; Population structure; RAPD

Despite the great commercial and economic importance of mussels, Mytilus galloprovincialis (Bivalvia, Mollusca) in Greece, little information is available concerning their population genetic structure. We used RAPD markers to examine genetic differentiation and potential impact of aquaculture practices and other anthropogenic activities on the genetic structure of two cultivated ... more

Forage; Genetic diversity; Plant improvement; RAPD; Species-specific markers

Among members of the Fabaceae family, native to the Brazilian Caatinga, the species Poincianella pyramidalis and P. bracteosa exhibit particular potential as forage for cattle, sheep and goats. With the aim of establishing genetic relationships within Poincianella, random amplified polymorphic DNA analysis was performed on eight accessions of P ... more

Elymus sibiricus; Genetic diversity; Population structure; RAPDs

Genetic diversity of Elymus sibiricus (Poaceae) was examined in eight populations from the southeast Qinghai-Tibet Plateau. We detected 291 RAPD polymorphic loci in 93 samples. The percentage of polymorphic bands (PPB) was 79%. Genetic diversity (HE) was 0.264, effective number of alleles (NE) was 1.444, Shannon’s information ... more

Chickpea; Genetic diversity; Molecular markers; Population structure; Principal coordinate analysis

Members of the primary gene pool of the chickpea, including 38 accessions of Cicer arietinum, six of C. reticulatum and four of C. echinospermum grown in India were investigated using 100 SSR markers to analyze their genetic structure, diversity and relationships. We found considerable diversity, with a mean of 4.8 alleles per locus (ranging from 2 to 11); ... more

Aegiphilla sellowiana; Genetic conservation; Genetic diversity; RAPD; Riparian population; Tropical tree

The Tibagi River, located in southern Brazil, is associated with a significant degree of environmental heterogeneity, along its 550 km extension. There is concern about the integrity of this river’s ecosystem, as human interference has been increasing. Aegiphila sellowiana (Lamiaceae) is an important pioneer tree species, commonly found near rivers; the fruit is consumed by ... more

Genetic diversity; Molecular marker; Piper; RAPD; SRAP

Random amplified polymorphic DNA (RAPD) and sequence-related amplified polymorphism (SRAP) analysis were applied to 74 individual plants of Piper spp in Hainan Island. The results showed that the SRAP technique may be more informative and more efficient and effective for studying genetic diversity of Piper spp than the RAPD technique. The overall level of genetic ... more

Genetic diversity; Mycelial compatibility groups; RAPD; Sclerotinia sclerotiorum; White mold

The genetic variability of 40 Sclerotinia sclerotiorum isolates from various fields widely distributed throughout Brazil and different host crops was analyzed using RAPD markers and mycelial compatibility groupings (MCGs). The isolates were characterized using 16 random primers of the OPERON series, which produced 121 DNA fragments. UPGMA cluster analysis using Jaccard’s genetic ... 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
