Learning by playing with DNAaQUAFISH: an interactive educational game about the...

The scientific applications related to Genetics are increasingly present in the daily lives of humanity, and from this, the teaching of genetics in schools becomes indispensable. This teaching helps to expand the knowledge of students, enabling and arousing interest in the quest to clarify their doubts and curiosities through questions and raising hypotheses, showing a creative behavior and seeking more and mor...

Isolation and characterization of 25 microsatellite DNA loci for Anopheles albi...

The Anopheles albitasis complex includes 6 species, and 3 are considered as malaria vectors in Brazil. Twenty-five polymorphic microsatellite DNA loci were isolated and characterized in 24-36 individuals from the neighborhood of Puraquequara, Manaus, Amazonas State, Brazil. The number of estimated alleles ranged from 2 to 10, the observed heterozygosity ranged from 0.182 to 0.897, and the expected heterozygosit...

Identification of Chromobacterium violaceum genes with potential biotechnologic...

Chromobacterium violaceum is a Gram-negative bacterium found in a wide variety of tropical and subtropical ecosystems. The complete genome sequence of C. violaceum ATCC 12472 is now available, and it has considerable biotechnological potential for various applications, such as environmental detoxification, as well as medical and agricultural use. We examined the biotechnological potential of C. violaceum for en...

Genetic structure and historical diversification of catfish Brachyplatystoma pl...

Brachyplatystoma platynemum is a catfish species widely distributed in the Amazon basin. Despite being considered of little commercial interest, the decline in other fish populations has contributed to the increase in the catches of this species. The structure, population genetic variability, and evolutionary process that have driven the diversification of this species are presently unknown. Considering that, i...

Isolation and characterization of polymorphic DNA microsatellite loci for Anoph...

Anopheles (Nyssorhynchus) triannulatus is a complex of 3 species. Thirteen polymorphic microsatellite loci were isolated and characterized in 20 to 25 individuals from Manaus (AM, Brazil). The number of alleles per locus varied from 3 to 10 (mean = 6.0). The observed heterozygosity ranged from 0.250 to 0.875 (mean = 0.680) and expected heterozygosity ranged from 0.376 to 0.844 (mean = 0.698). Two loci exhibited...

The Genome of Anopheles darlingi, the main neotropical malaria vector

Anopheles darlingi is the principal neotropical malaria vector, responsible for more than a million cases of malaria per year on the American continent. Anopheles darlingi diverged from the African and Asian malaria vectors ∼100 million years ago (mya) and successfully adapted to the New World environment. Here we present an annotated reference A. darlingi genome, sequenced from a wild population of males and f...

Genetic diversity and structure of astrocaryum jauari (mart.) palm in two amazo...

Astrocaryum jauari is a non-domesticated palm that is exploited by poachers. Our objective was to investigate the organization of the genetic diversity and structure of three A. jauari populations. The study was carried out in the state of Amazonas, between the municipalities of Coari and Manaus. Nine microsatellite loci were used for the genetic analyses. High genetic variation was found, with a mean number of...

DNA barcoding in pencilfishes (Lebiasinidae: Nannostomus) reveals cryptic diver...

Nannostomus is comprised of 20 species. Popularly known as pencilfishes the vast majority of these species lives in the flooded forests of the Amazon basin and are popular in the ornamental trade. Among the lebiasinids, it is the only genus to have undergone more than one taxonomic revision. Even so, it still possesses poorly defined species. Here, we report the results of an application of DNA barcoding to the...
