Native of the Amazon, the nanche (Byrsonima crassifolia) is a fruit cultivated by family farmers and used in cooking; as such, it represents an opportunity for regional agribusiness. The Embrapa Eastern Amazon set up an active germplasm bank (BAG) consisting of 22 accessions sampled in 11 municipalities of Pará State. Due to its economic potential, there is an interest to advance the genetic br...

Species of Botrychium reproduce by spores that form subterranean gametophytes and a few, like B. pumicola, also reproduce asexually with subterranean sporophytic gemmae. The goal of this study was to examine the genetic diversity of B. pumicola populations and to better understand the role of gemmae. Ninety-nine individuals from three monitored populations were sampled. The technique of inter-s...

Cucumber is an important vegetable crop grown worldwide. Genetic diversity and similarity among 11 cucumber genotypes viz. PCUCP-2, PCUCP-3, Nun-3139, Nun-3121, Nun-3141, Infinity, Isatis and Kian and PCUC-8, PCUC15 and PCUC-28 were grown under greenhouse conditions in G. B. Pant University of Agriculture and Technology, Pantnagar. Fresh and young leaves were collected from each genotype. The l...

Improvement of high yielding, disease resistant silkworm strains became imminent to increase production of silk, which is a major revenue earner for sericulturists. Since environment interacts with phenotype, conventional breeding did not result in commendable yield improvement in synthetic strains of silkworm, Bombyx mori. Identification of DNA markers associated with different economically im...

Study of Population Structure Capparis Spinosa and Analysis Morphological Traits using ISSR SCoT Markers

castor (ricinus communis l.) is one of the most ancient medicinal oil crops in the world. it has been vastly distributed in different parts of iran. in the present study, the inter simple sequence repeat (issr) markers were used to evaluate the molecular genetic diversity among and within 12 castor accessions collected from 7 regions of iran. totally, 16 issr primers amplified 166 loci, of whic...

Inferences regarding hybridization rely on genetic markers to differentiate parental taxa from one another. Intersimple sequence repeat (ISSR) markers are based on single-primer PCR reactions where the primer sequence is derived from di- and trinucleotide repeats. These markers have successfully been used to assay genetic variability among cultivated plants, but have not yet been tested in natu...

Posidonia oceanica is an endemic seagrass species in the Mediterranean Sea. Due to its ecological importance, it has been the subject of several genetic studies aimed at increasing general knowledge of the system and helping to define appropriate management strategies. We compared the efficiency of 2 different classes of molecular markers, ‘inter simple sequence repeats’ (ISSRs) and ‘simple seq...

Sophora davidii (Franch.) Kom. ex Pavol is an important medicinal plant and a feeding scrub with ecological value. The effects of different gamma irradiation doses (20-140 Kr) on seed germination and seedling morphology were investigated in S. davidii, and intersimple sequence repeat (ISSR) markers were used to identify the DNA polymorphism among mutants. Significant variations were observed fo...
