Bothrops moojeni; conservation genetics; Genetic structure; Genetic variability; RAPD; Vipers

Bothrops moojeni is an abundant venomous snake responsible for most of the snakebite cases in the Central region of Brazil and as a result of the anthropogenic habitat disturbance, such as the increase in extensive farming, the range of B. moojeni has been greatly fragmented. Here, we obtained genomic DNA from a total of 75 snakes belonging to four populations. Genetic ... more

Akodon; Akodon cursor; Cryptic species; Genetic variability; Hantavirus reservoir; RAPD

The cursor complex is a group within the Akodon genus of South American rodents, formed by Akodon cursor and A. montensis. Correct distinction between these two species is of great importance since they can harbor different Hantavirus strains. These species are only distinguishable by means of karyotypic or internal anatomic features, requiring ... more

Cacao; Exoenzymes; Genetic variability; RAPD; Witches’ broom

We evaluated the genetic and physiological variability of Moniliophthora perniciosa obtained from healthy and diseased branches of cacao (Theobroma cacao) plants. The diversity of the isolates was evaluated by RAPD technique and by studies of virulence and exoenzyme production. The genetic variability of endophytic and pathogenic M. perniciosa was evaluated in ... more

Genetic variability; Heliconia; Molecular marker; Phylogenetic relationships; RAPD; Zingiberales

The family Heliconiaceae contains a single genus, Heliconia, with approximately 180 species of Neotropical origin. This genus was formerly allocated to the family Musaceae, but today forms its own family, in the order Zingiberales. The combination of inverted flowers, a single staminode and drupe fruits is an exclusive characteristic of Heliconia. Heliconias are ... more

AFLP; Ficus carica; Genetic variability; RAPD

The fig (Ficus carica L.) is a fruit tree of great world importance and, therefore, the genetic improvement becomes an important field of research for better crops, being necessary to gather information on this species, mainly regarding its genetic variability so that appropriate propagation projects and management are made. The improvement programs of fig trees using ... more

Amazon; Biodiversity; Cacauí; Genetic variability; ISSR

The genus Theobroma found in the Amazon region is composed of 22 species, including Theobroma speciosum, better known as cacauí. These species are constantly threatened by forest fragmentation caused by human activities and require conservation strategies and management aimed at preserving them in their natural environments. The main objective of this study was to ... more

ISSR; Molecular marker; RAPD

Dalbergia oliveri is a leguminous tree of the Fabaceae family. This species is popular and valuable in Vietnam and is currently listed on the Vietnam Red List and on the IUCN Red List as endangered. Two PCR techniques using RAPD and inter-simple sequence repeat (ISSR) markers were used to make a comparative analysis of genetic diversity in this species. Fifty-six polymorphic primers (29 ... more

Fusarium verticillioides; Intron; ISSR; RAPD

Fusarium verticillioides is a pathogen of agriculturally im­portant crops, especially maize. It is considered one of the most impor­tant pathogens responsible for fumonisin contamination of food products, which causes severe, chronic, and acute intoxication in humans and ani­mals. Moreover, it is recognized as a cause of localized infections in im­munocompetent patients and ... more

Interspecific hybrids between cultivars of eggplant (Solanum melongena L.) and its wild relative S. torvum, which has disease resistance and desirable traits for crop improvement, were obtained by cross-hybridization and embryo rescue. Twenty-one hybrid progenies were obtained and examined based on morphological traits, RAPD and ISSR markers. Five of them were confirmed ... more

Agronomic traits; Genetic variation; Gossypium hirsutum L.; ISSR; RAPD; SSR

Cotton is one of the most economically important crops in Iran; hybridization is a means to increase the genetic diversity and obtain new elite cultivars in this crop. We examined agronomic characteristics and molecular genetic diversity in the Opal cotton (Gossypium hirsutum) cultivar and in F2 progenies. Ten homo-primers and seven hetero-primers of 26 RAPD primers ... more
