ABSTRACT DNA markers tightly linked to resistance (R) genes provide a very powerful tool for both marker-assisted selection in plant breeding and positional cloning of R genes. In the present study, a linkage of random amplified polymorphic DNA (RAPD) markers to the single dominant gene (Cr2) for resistance to white pine blister rust fungus (Cronartium ribicola) was investigated in western whit...

Higher plants are ubiquitously colonized with fungal endophytes that often lack readily detectable structures. Current study examines the distribution of endophytic fungal communities within Karanja plants and diversity of novel fungal endophyte Alternaria solani isolates collected from different locations of Sanganer region of Rajasthan. Results confirmed that A. solani is a major fungal endop...

The molecular marker is a useful tool for assessing genetic variations and resolving cultivar identities. Information on genetic diversity and relationships among rice landraces from Bangladesh is currently very limited. Thirty-five rice genotypes including 33 landraces and 01 HYV of Bangladesh and 1 Indian landrace of particular interest to breeding programs were evaluated by means of random a...

Understanding the genetic variation in germplasm is of utmost importance for crop improvement. Therefore, efforts were made to analyse the molecular marker based genetic diversity of 20 Annona genotypes from five different species of family Annonaceae. During analysis, a set of 11 RAPD primers yielded a total of 152 bands with 80.01 % polymorphism and PIC for RAPD ranged from 0.86 to 0.92 with ...

introduction despite the fact that iran is one of the major chickpea (cicer arietinum l.) center of origins, limited information is available regarding chickpea genetic variation and diversity. genetic diversity information is crucial for the choice of proper parents to establish new breeding programs. chickpea germplasm is poor, suggesting the need for gaining enough knowledge of genetic diver...

Beet curly top virus, often referred to as Curly top virus (CTV), is an important virus disease of common bean in the semiarid regions of the United States, Canada, and Mexico and the only effective control is genetic resistance. Our objective was to determine if dry bean landrace G122, which lacks the Bct gene for resistance to CTV, contains novel resistance to the virus. Two populations, GT-A...

Penicillium is a genus of ascomycetous fungi of major importance in the environment, food and drug production. It produces penicillin, a molecule that is used as an antibiotic, this kills or stops the growth of certain kinds of bacteria inside the body. In the present investigation morphological characterization of Penicillium species was carried out in two different media (PDA and Czapek Dox)....

A composite genetic linkage map for the yellow fever mosquito Aedes aegypti was constructed based on restriction fragment length polymorphism (RFLP), single nucleotide polymorphism (SNP) and single strand conformation polymorphism (SSCP) markers. The map consists of 146 marker loci distributed across 205 cM, and includes several morphological mutant marker loci. Most of the genetic markers are ...

We present protocols and conditions for specimen storage, DNA extraction and storage, and the subsequent RAPD (Random Amplified Polymorphic DNA) profiling of spiders . Three common UK species, Lepthyphantes tenuis (Blackwall 1852), Enoplognatha ovata (Clerk 1757) and Clubiona reclusa (Cambridge 1863), members of the Linyphiidae, Theridiidae and Clubionidae respectively, were chosen to serve as ...

RAPD is a PCR based technique which involves the use of single arbitrary. Advantages disadvantages, limitations and applications of RAPD.RAPD is a modification of the PCR in which a single, short and arbitrary. Therefore, RAPD technique can be performed in a moderate laboratory for most of.sophisticated equipment has made the RAPD technique valuable although. Tartflmann odak noktas ise de, RAPD...
