Genetic diversity of cacao accessions selected for resistance to witches’ broom based on RAPD markers

Genetic and Biological Diversity of Trichoderma stromaticum, a Mycoparasite of the Cacao Witches'-Broom Pathogen.

ABSTRACT The witches'-broom disease, caused by the basidiomycete Crinipellis perniciosa, is the most limiting factor for cacao cultivation in Brazil. Trichoderma stromaticum is a mycoparasite of the witches'-broom pathogen of cacao that is currently being applied in the field to manage the disease in Bahia State, Brazil. In this work, molecular and traditional methods were used to study the gen...

Assessment of genetic diversity in Costus pictus accessions based on RAPD and ISSR markers

Costus pictus, belonging to the family Costaceae, is one of the valuable medicinal plants with its anti-diabetic property. Despite ever-increasing demand from the pharmaceutical industry, this species is being less exploited at molecular level. Hence, an effort has been made in the present study to characterize the 15 accessions of C. pictus collected from different geographical regions of Indi...

Potential of RAPD and ISSR markers for assessing genetic diversity among Stevia rebaudiana Bertoni accessions

In the present study, genetic diversity among 16 collections of Stevia rebaudiana Bertoni was assessed to compare the efficiency of two-marker systems over one marker using RAPD and ISSR markers. How well these two marker systems discriminated the Stevia collections was compared. In fact, all the Stevia accessions included in the present study have been growing under different altitudes, rangin...

Comparative Analyses of the Genetic Diversity Among Bread Wheat Genotypes Based on RAPD and SSR Markers

Single nucleotide polymorphisms from Theobroma cacao expressed sequence tags associated with witches' broom disease in cacao.

In order to increase the efficiency of cacao tree resistance to witches' broom disease, which is caused by Moniliophthora perniciosa (Tricholomataceae), we looked for molecular markers that could help in the selection of resistant cacao genotypes. Among the different markers useful for developing marker-assisted selection, single nucleotide polymorphisms (SNPs) constitute the most common type o...
