Onion anthracnose, caused by Colletotrichum gloeosporioides, is one of the main diseases of onions in the State of Pernambuco. We examined the pathogenicity of 15 C. gloeosporioides strains and analyzed their genetic variability using RAPDs and internal transcribed spacers (ITS) of the rDNA region. Ten of the strains were obta.. Read More»

Sugarcane culture is an important source of income for the Brazilian economy. The aim of this study was to identify somaclonal variation in sugarcane varieties RB943365 and RB92579 arising from micropropagation using inter-simple sequence repeat (ISSR) DNA markers. The evaluated plants were generated from the in vitro propagation of shoot tips grown in MS.. Read More»

Genetic diversity of the Neotropical tree Hancornia speciosa Gomes in natural populations in Northeastern Brazil
Authors: H.J. Jimenez, L.S.S. Martins, A.V.V. Montarroyos, J.F. Silva Junior, A.L. Alzate-Marin and R.M. Moraes Filho
Mangabeira (Hancornia speciosa Gomes) is a fruit tree of the Apocynaceae family, which is native to Brazil and is a very important food resource for human populations in its areas of occurrence. Mangabeira fruit is collected as an extractive activity, and no domesticated varieties or breeding programs exist. Due to a reduction in the area of ecosystems wh.. Read More»

DNA variation and polymorphism in Tunisian plum species (Prunus spp): contribution of flow cytometry and molecular markers
Authors: H. Ben Tamarzizt, D. Walker, S. Ben Mustapha, D. Abdallah, G. Baraket, A. Salhi Hannachi and S. Zehdi Azzouzi
Plums (Prunus spp) are among the most important stone fruit crops in the world. European (Prunus domestica) and Japanese (Prunus salicina) plums are characterized by different levels of ploidy. Because genetic variability is the prerequisite for any plant-breeding program, we aimed to establish the taxonomic status of Tunisian plums and study their geneti.. Read More»

A novel molecular marker for the study of Neotropical cichlid phylogeny
Authors: T.M.C. Fabrin, L.S. Gasques, S.M.A.P. Prioli and A.J. Prioli
The use of molecular markers has contributed to phylogeny and to the reconstruction of species’ evolutionary history. Each region of the genome has different evolution rates, which may or may not identify phylogenetic signal at different levels. Therefore, it is important to assess new molecular markers that can be used for phylogenetic reconstructi.. Read More»

Agro-ecological variations of sheath rot disease of rice caused by Sarocladium oryzae and DNA fingerprinting of the pathogenâ??s population structure
Authors: M. Tajul Islam Chowdhury, M. Salim Mian, M.A. Taher Mia, M.Y. Rafii and M.A. Latif
To examine the impact of regional and seasonal variations on the incidence and severity of sheath rot, a major seed-borne disease of rice caused by Sarocladium oryzae, data on incidence and severity were collected from 27 selected fields in the Gazipur, Rangpur, Bogra, Chittagong, Comilla, Gopalgonj, Jessore, Manikgonj, and Bhola districts of Bangladesh i..

ISSR markers in wild species of Passiflora L. (Passifloraceae) as a tool for taxon selection in ornamental breeding
Authors: A.G.R. Sousa, M.M. Souza, C.A.F. Melo and G.A. Sodr?©
Inter simple sequence repeat (ISSR) molecular markers were developed and used to investigate interspecific genetic variation in 25 wild species of Passiflora preserved in an active germplasm bank (BAG-Passifloras); intraspecific diversity was also analyzed in P. cincinnata accessions. Of 31 primers tested, 20 identified polymorphic loci with a total of 33.. Read More»

Polymorphisms in the GHRL gene and their associations with traits of economic interest in beef cattle

The hormone ghrelin is produced in the stomach wall, has an orexigenic function, stimulates growth hormone secretion, and affects the energy balance of the animal. Therefore, the ghrelin gene (GHRL) is considered to be a good candidate marker for the identification of traits of great economic importance in cattle, such as those associated with feed intake..
