A new species of cixiid planthopper (Hemiptera: Fulgoroidea) in the genus Oecleus Stål, sergipensis n. sp., is described from Sergipe State, Brazil. This taxon associated with coconut (Cocos nucifera L.) and date palm (Phoenix L). The was detected Auchenorrhyncha surveys to find potential vectors lethal yellowing type syndrome. first report Sequence data mitochondrial cytochrome c oxidase subunit I (COI) barcoding region obtained accessioned into GenBank.
The root-knot nematode Meloidogyne exigua is a parasite which attacks the Arabica coffee tree (Coffea sp.) and its eradication from infested areas practically impossible. wide dissemination of this across plantations in south state Minas Gerais has been causing great damage to producers area. Previous studies showed that simple inheritance gene present C. canephora, designated Mex-1, controls M. resistance. Some genetic breeding programs have developed resistant lines through introgression...
Phylogeographic analysis of the Coffea subgenus was performed using data on plastid DNA sequences and interpreted in relation to biogeographic African rain forest flora. Parsimony Bayesian analyses trnL-F, trnT-L atpB-rbcL intergenic spacers from 24 species revealed two main clades whose distribution overlaps west equatorial Africa. Comparison trnL-F obtained GenBank for 45 Cameroon, Madagascar, Grande Comore Mascarenes low divergence between Madagascan species, suggesting a rapid radial...
Phytoene desaturase (PDS) is a plant enzyme involved in carotenoid biosynthesis. The PDS gene has been used as selective marker for genome editing several species, including banana (Musa spp.). Its knockout promotes dwarfism and albinism, characteristics that are easily recognizable highly favorable. In Musa spp., the A increases fruit production quality, whereas B associated with tolerance to biotic abiotic stresses. objective of this study was identify molecular discriminate genomes...
The diversity and genetic relationships among two accessions of tall coconut palms collected in Brazil seven introduced from different geographic regions the world were analyzed using 25 microsatellite primers, 19 which polymorphic detected between 4 10 alleles per locus, with an average 6.57. observed expected heterozygosity ranged 0.25 0.40 Rennell Islands Tall (RIT) accession to 0.54 0.62 Polynesian (PYT) accession. analysis structure resulted formation five distinct groups. first group...
Abstract Coffea canephora (2n = 2x 22 chromosomes) is a species with extensive genetic diversity and desirable agronomic traits for coffee breeding programs. However, obtaining new cultivar through conventional techniques may require more than 30 years of crossing cycles selection, which hampers the effort keeping up market demands rapidly proposing resilient to climate change varieties. Although, application modern biotechnology tools such as precision engineering technologies enable faster...
The genetic complexity in the genus Musa has been subject of study many breeding programs worldwide. Parthenocarpy, female sterility, polyploidy different cultivars and limited amount genomic information make production new banana difficult time consuming. In addition, it is known that part related wild species contain numerous chromosomal rearrangements. order to produce more effectively breeders must better understand differences potential crossing parents for introgression hybridization,...
The genetic variability of 40 accessions of_C. arabica was evaluated using a combination the random amplified polymorphic DNA (RAPD) technique and restriction digestion genomic DNA. relatedness among all were initially 195 RAPD primers which revealed very low level variation. To improve efficiency in detection polymorphism, submitted to with endonucleases prior PCR amplification. A total 24 combined rendered 318 bands, 266 (83.65%) polymorphic. associations genotypes estimated...
Knowledge of the genetic variability among genotypes is important for transfer useful genes and to maximize use available germplasm resources. This study was carried out assess 14 elite Coffea arabica cultivars using random amplified polymorphic DNA (RAPD) associated with a prior digestion genomic restriction endonucleases. The accessions were obtained from collection maintained at Instituto Agronômico do Paraná (IAPAR), located in Londrina, Paraná, Brazil. Twenty-four informative RAPD...
Varronia curassavica Jacq. is a medicinal and aromatic plant from Brazil with significant economic importance. Studies on genetic diversity in active germplasm banks (AGB) are essential for conservation breeding programs. The aim of this study was to analyze the V. accessions AGB Medicinal Aromatic Plants Federal University Sergipe (UFS), using inter-simple sequence repeat molecular markers. Twenty-four primers were tested, 14 polymorphic informative, resulting 149 bands 97.98% polymorphism....
O objetivo deste trabalho foi identificar isolados brasileiros de Ralstonia solanacearum quanto a filotipos e sequevares, determinar sua diversidade genética, realizar associação da estrutura genética do patógeno com classificação origem geográfica um marcador molecular para diagnose moko-da-bananeira. Um grupo 33 R. solanacearum, coleção Embrapa Tabuleiros Costeiros, coletado diversos hospedeiros, caracterizado por meio PCR em sequência palindrômica extragênica repetitiva (rep-PCR) RAPD....
The Saprolegniosis causes major reduction egg hatching rate by angelfish (Pterophyllum scalare); therefore, we investigated the effectiveness of two Terminalia catappa extracts (27 ℃ and 80 ℃) against S. parasitica on fish eggs. Mycelium growth was evaluated in vitro at 0, 2.5, 5.0 10 g/L for 96 h, solid liquid medium culture. In an vivo assay, tested lower concentrations hot extract (25, 50 100 mg/L) to prevent infection zoospores. aqueous most effective, 5 demonstrated great efficiency...
BackgroundActinomycetes may account for 10 to 30% of the totalsoil rhizosphere microorganisms.
