Microsatellite markers have been widely used in the quantification of genetic variability and for genetic breeding in Musa spp. The objective of the present study was to evaluate the discriminatory power of microsatellite markers derived from ‘Calcutta 4’ and ‘Ouro’ genomic libraries, and to analyze the genetic variability among 30 banana accessions. Thirty-eight markers were ... more
Babesiosis is an infectious hemolytic disease that occurs worldwide, and is caused by a protozoan of the Babesia genus (Apicomplexa). Little is known about this genus; therefore, this study conducted a molecular characterization of Babesia spp in naturally infected dogs in northern Brazil. Blood samples were collected from 172 dogs from metropolitan Belém, and screened ... more
Some species of Anacardium (Anacardiaceae) produce fruits and pseudofruits that are smaller than those of the common cashew (Anacardium occidentale) and, for this reason, are known collectively in Brazil as “cajuí”. Despite their economic value in the food market and their important environmental and ecological functions, cajuí trees remain ... more
The soybean stem fly (Melanagromyza sojae) is a widely distributed and highly damaging soybean pest, recently introduced to Brazil and neighboring countries. The bioecology of this pest under South American growing conditions is largely unknown, including how infesting populations survive throughout the winter. Fly larvae collected in August 2019 from Persian ... more
Ginger (Zingiber officinale Roscoe) is a self-incompatible plant and has high rates of infertility; its genetic diversity only occurs via processes of mutation and natural selection. Since ginger is important as a condiment and as an herbal medicine, understanding its diversity to a greater degree can contribute both to its conservation and to its use in ... more
It is essential that the genetic variability of preserved accessions germplasm banks be evaluated and quantified, which allows, for example, the detection of duplicates, generating more reliable data, especially for groups of plants that have a wide genetic variability, as in the case of the Capsicum genus. . We examined the DNA from the leaves of nine ... more
Chikungunya virus (CHIKV) is an RNA virus from the family Togaviridae transmitted primarily by Aedes mosquitoes. The first report of CHIKV infection in Brazil dates to 2014; since then, the virus has become a major public health challenge. The main goal of this study was to perform a phylogenetic analysis of CHIKV isolates from ... more
The objective of this study was to evaluate genetic variability and select putative mutants of Terra Maranhão plantain cultivar (AAB genome) subjected to gamma radiation based on agronomic data and inter simple sequence repeat molecular marker profiles using the Ward-MLM strategy. A total of 233 irradiated plants and 41 controls were assessed. The agronomic and molecular data were ... more
The Neotropical Heliconia genus contains highly diversified plants and up to 220 species have been reported from the north of Mexico to the South of Brazil. Heliconia are cultivated as ornamental garden plants and as cut flowers. All species can be propagated by seeds or vegetatively, through rhizomes. Depending on the species, an individual plant can spread and form ... more
Plantains in Brazil are produced from the `Terra Maranhão’, ‘Terrinha’ and ‘D´Angola’ cultivars, which are all susceptible to black Sigatoka, weevils and nematodes. Therefore, the development of resistant plantain cultivars with agronomic characteristics aligned with market demands is the most efficient way to overcome these barriers regarding fruit production. The ... more
