Brachiaria humidicola (Rendle) Schweick. is a warm-season grass commonly used as forage in the tropics. Accessions of this species were collected eastern Africa and massively introduced into South America 1980s. Several these accessions form germplasm collection at Brazilian Agricultural Research Corporation. However, apomixis, ploidy, limited knowledge genetic basis have constrained breeding activities. The objectives work to identify variability B. using microsatellite markers compare...
The African species Urochloa humidicola (Rendle) Morrone & Zuloaga (syn. Brachiaria Schweick.) is an important perennial forage grass found throughout the tropics. This polyploid, ranging from tetra to nonaploid, and apomictic, which makes genetic studies challenging; therefore, number of currently available resources limited. genomic architecture evolution U. molecular markers linked apomixis were investigated in a full-sib F1 population obtained by crossing sexual accession H031 apomictic...
Pasture is the main food source for more than 200 million cattle heads in Brazil. Although Brazilian forage breeding programs have successfully released well-adapted, high-yielding cultivars over years, use of genomic tools these currently limited. These are required to tackle challenges tropical In this context, notes lists research priorities raised at workshop "Breeding Forages Genomic Era", which necessary accelerate next-generation forages and allow breeders increase genetic gains....
Screening for resistance to insect pests is one of the early stages grass breeding programs. Pasture spittlebugs are sap-sucking insects that potentially cause severe damage turfgrasses, including loss functional quality and perenniallity. The Brazilian flora has a large number species with wide morphological variability adaptability different soil climate conditions can be used as lawns. However, no study screened turfgrass genotypes spittlebug attack. In this study, we evaluated intra-...
Abstract Background Paspalum notatum exhibits both sexual and apomictic cytotypes and, thus, is considered a good model for studies of apomixis because it facilitates comparative approaches. In this work, transcriptome sequencing was used to compare contrasting P. identify differential expression patterns candidate genes involved in the regulation trait. Results We built comprehensive using leaf inflorescence from tetraploids diploids/tetraploids coexpression network based on pairwise...
Urochloa humidicola (Koronivia grass) is a polyploid (6x to 9x) species that used as forage in the tropics. Facultative apospory apomixis present most of genotypes this species, although one individual has been described sexual. Molecular studies have restricted molecular marker approaches for genetic diversity estimations and linkage map construction. The objectives study were describe compare leaf transcriptome two important are highly divergent terms their phenotypes reproduction modes:...
Microsatellite (SSR) markers were developed for the following tropical forage species, using accessions available from plant genetic resources (PGR) collections held by EMBRAPA (Brazilian Agricultural Research Corporation): Brachiaria brizantha, B. humidicola, Panicum maximum, Paspalum spp., Stylosanthes capitata, S. guianensis, macrocephala, Calopogonium mucunoides and Centrosema spp. The used to analyze population structure diversity, evolution origin of variability in center origin,...
Peanut is a major oilseed crop worldwide. In the Brazilian peanut production, silvering thrips and red necked worm are most threatening pests. Resistant varieties considered an alternative to pest control. Many wild diploid Arachis species have shown resistance these pests, can be used in breeding by obtaining hybrid of A B genomes subsequent polyploidization with colchicine, resulting AABB amphidiploid. This amphidiploid crossed cultivated (AABB) provide genes interest cultivar. this study,...
Artificial hybridization plays a fundamental role in plant breeding programs since it generates new genotypic combinations that can result desirable phenotypes. Depending on the species and mode of reproduction, controlled crosses may be challenging, contaminating individuals introduced accidentally. In this context, identification such contaminants is important to avoid compromising further selection cycles, as well genetic genomic studies. The main objective work was propose an automated...
Abstract The characterization of genetic resources is essential to carry out a breeding program. This study aimed characterize Paspalum genotypes with potential use as soil surface covering support programs on the development turf cultivars. Forty‐three genotypes, comprising 11 species, were evaluated. embryo‐sacs structure was determined by cleared ovaries analysis and eight accessions classified sexual, 15 apomictic, 20 presenting facultative apomixis. Most have 40 chromosomes, exception...
Paspalum plicatulum is a perennial rhizomatous grass with natural diploid and polyploid cytotypes. It member of Plicatula, which has historically been recognized as highly complex group containing species ecological, ornamental forage importance. The nature the P. genome makes it challenging for genetic research. This study aimed to develop characterize microsatellite molecular markers in evaluate their transferability other Plicatula species.Microsatellite sequences were identified from...
We developed a new set of microsatellite markers for studying the genome janaguba tree, Himatanthus drasticus (Mart.) Plumel, which is used in folk medicine northeastern Brazil. These novel are being to evaluate effect harvesting on genetic structure and diversity natural populations this species. •Microsatellite loci were isolated from an enriched H. genomic library. Nine primer pairs successfully amplified polymorphic regions, with average 8.5 alleles per locus. The values observed...
Abstract This study investigated the agronomic, nutritive value, cytogenetic, molecular, and reproductive aspects of twenty‐five Paspalum accessions to support breeding programs. The agronomic value were evaluated in a randomized block experimental design with four replications, monthly repeated measures for 2 years. For molecular characterization 16 microsatellite markers developed different species previous works used. number chromosomes was determined by visualizing meiotic cells DNA...
Espécies de Paspalum são importantes constituintes nas pastagens nativas regiões tropicais e subtropicais das Américas. vaginatum é nativo áreas litorâneas no Brasil amplamente utilizado em campos golfe nos Estados Unidos devido sua robustez tolerância a estresses abióticos como seca, encharcamento salinidade. Bactérias localizadas interior dessa espécie vegetal (endofíticas) podem ser parcialmente responsáveis pela essas condições extremas. O uso bactérias capazes promover o crescimento...
