The population genetics of the migratory rice leaf roller, Cnaphalocrocis medinalis (Lepidoptera: Pyralidae), was characterized using the maternally inherited mitochondrial A+T-rich region and bi-parentally inherited nuclear internal transcribed spacer 2 (ITS2). One hundred and eighty-seven specimens of the rice leaf roller collected from 13 Korean and Chinese localities revealed ... more

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

Chickpea; Genetic diversity; Polymerase chain reaction; Random amplified polymorphic DNA

Genetic diversity analysis of chickpea germplasm can provide practical information for the selection of parental material and thus assist in planning breeding strategies. Chickpea seed is a good source of carbohydrates and proteins, constituting 80% of the total dry seed weight. Released cultivars and advanced lines of 30 chickpea genotypes were subjected to RAPD analysis for assessment ... 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

Anatomy; Genetic diversity; ISSR markers; Micromorphology; Sweet and chili pepper

Capsicum species are frequently described in terms of genetic divergence, considering morphological, agronomic, and molecular databases. However, descriptions of genetic differences based on anatomical characters are rare. We examined the anatomy and the micromorphology of vegetative and reproductive organs of several Capsicum species. Four Capsicum accessions ... more

Arctic fox; Genetic diversity; Germplasm; SRAP marker

Sequence-related amplified polymorphism (SRAP) is a recently developed molecular marker technique that is stable, simple, reliable, and achieves moderate to high numbers of codominant markers. This study is the first to apply SRAP markers in a mammal, namely the Arctic fox. In order to investigate the genetic diversity of the Arctic fox and to provide a reference for use of its germplasm ... more

Aschersonia placenta; China; Genetic diversity; ISSR

Aschersonia placenta had been recognized as an important fungal pathogen of whiteflies. In recent years, natural occurrence of Aschersonia in whitefly populations was observed in many citrus orchards in the southern regions of China. We analyzed 60 A. placenta isolates obtained from Chinese citrus orchards, using inter-simple sequence repeats to examine the ... more

Coilia ectenes; Genetic diversity; Microsatellite marker

Coilia ectenes (Jordan and Seale 1905) is an important anadromous species that is an important resource at risk of extinction because of over-fishing, pollution, and coastal construction. To evaluate the genetic diversity of C. ectenes for use in breeding programs, elite microsatellite-enriched libraries were constructed and novel microsatellite markers were developed, ... more

Cosmos; DNA profiles; Genetic diversity; Inter-simple sequence repeat (ISSR); Random amplified polymorphic DNA (RAPD)

The genus Cosmos is native of America and is constituted by 34 species; 28 of them are endemic of Mexico. The cosmos are used as a nematicide, antimalarial, and antioxidative agent. The aim of this study was to estimate the genetic diversity among 7 cosmos species based on random amplified polymorphic DNA (RAPD) and inter-simple sequences repeats (ISSR) markers. With RAPD markers ... more

Protein and DNA polymorphismswere surveyed among seven accessions of wild fenugreek (Trigonellafoenum-graecum L.) to estimate their genetic diversity and relationships. Samples were obtained from diverse ecogeographical areas in Saudi Arabia and Yemen. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis of seed storage protein showed genetic variations ... more
