Comparison of ddRADseq and EUChip60K SNP genotyping systems for population gene...
Aguirre, Natalia Cristina; Villalba, Pamela Victoria; García, Martín Nahuel; Filippi, Carla Valeria; Rivas, Juan Gabriel; Martínez, María CarolinaEucalyptus dunnii is one of the most important Eucalyptus species for short-fiber pulp production in regions where other species of the genus are affected by poor soil and climatic conditions. In this context, E. dunnii holds promise as a resource to address and adapt to the challenges of climate change. Despite its rapid growth and favorable wood properties for solid wood products, the advancement of its impro...
Patterns of DNA methylation changes in elite Eucalyptus clones across contrasti...
Jacinto Pereira, Wendell; de Castro Rodrigues Pappas, Marília; Camargo Campoe, Otávio [UNESP]; Stape, José Luiz; Grattapaglia, DarioMade available in DSpace on 2020-12-12T01:29:27Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-10-15; Phenotypic plasticity refers to the ability of a single genotype to express distinct phenotypes in response to the environment, a crucial feature for sessile organisms like forest trees, especially in a scenario of global climate change. Several studies show that epigenetic regulation plays an important...
The complete genome sequence of Chromobacterium violaceum reveals remarkable an...
Vasconcelos, Ana Tereza; De-Almeida, Darcy Fontoura; Hungría, Mariangela; Guimarães, Cláudia Teixeira; Antônio, Regina VasconcellosChromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spre...
Selecting for stable and productive families of eucalyptus urophylla across a c...

No. of bitstreams: 0 Previous issue date: 2019-01-01; Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Universidade de São Paulo; To identify stable and productive Eucalyptus urophylla S.T. Blake families across diverse climate zones in Brazil, we evaluated growth and survival of 322 open-pollinated families derived from 13 genetically improv...
Positioning of the major locus for Puccinia psidii rust resistance (Ppr1) on th...
Guimarães, Lucio M. S.; Mamani, Eva M. C.; Bueno, Nathalia W.; Faria, Danielle A.; Lau, Douglas; Alfenas, Acelino C.; Grattapaglia, DarioIn this report the major locus for Puccinia psidii rust resistance, Ppr1, was positioned on the reference genetic map for Eucalyptus. Additionally, its position was validated by association genetics in a related and two unrelated pedigrees involving different Eucalyptus grandis resistant trees crossed to individuals of two other species, Eucalyptus tereticornis and Eucalyptus camaldulensis. These results are co...
Pollen-mediated gene flow across fragmented clonal stands of hybrid eucalypts i...

No. of bitstreams: 0 Previous issue date: 2015-11-15; We investigated the rate of pollen-mediated flow and realized reproductive success at increasing distances from the source, across fragmented clonal stands of hybrid eucalypts in Brazil by parentage analysis of grown out seedlings using genetic data at 15 microsatellite markers. Two study areas were emp...

Silva, Paulo H.M. da [UNESP]; Sebbenn, Alexandre M. [UNESP]; Grattapaglia, Dario; Conti, José Luiz F.Made available in DSpace on 2018-12-11T16:44:50Z (GMT). No. of bitstreams: 0 Previous issue date: 2017-02-01; Confined field trials of genetically modified (GM) trees are the essential step toward the identification of the most productive cultivars and the assessment of the likely environmental impacts of the GM trees including the potential for gene flow by pollen and distance dispersal by seeds. Our study inv...
A high-density transcript linkage map with 1,845 expressed genes positioned by ...
Neves, Leandro G.; Mamani, Eva MC.; Alfenas, Acelino C.; Kirst, Matias; Grattapaglia, DarioTechnological advances are progressively increasing the application of genomics to a wider array of economically and ecologically important species. High-density maps enriched for transcribed genes facilitate the discovery of connections between genes and phenotypes. We report the construction of a high-density linkage map of expressed genes for the heterozygous genome of Eucalyptus using Single Feature Polymor...
Genetic mapping and validation of QTLs associated with resistance to Calonectri...
Zarpelon, Talyta Gafassi; Guimarães, Lúcio Mauro da Silva; Faria, Danielle Assis; Coutinho, Marcelo Magalhães; Cápua Neto, BrazCalonectria leaf blight (CLB) caused by Calonectria pteridis is one of the main leaf diseases in Brazilian Eucalyptus plantations in warm climates with prolonged periods of rain. The main symptoms are leaf spots followed by intense defoliation in highly susceptible plants. Exploiting the existing inter- and intraspecific variability for defoliation is the best option to control this disease. Nevertheless, nothi...
Regional heritability mapping and genome-wide association identify loci for com...
Resende, Rafael Tassinari; Resende, Marcos Deon Vilela; Silva, Fabyano Fonseca; Azevedo, Camila Ferreira; Takahashi, Elizabete KeikoAlthough genome-wide association studies (GWAS) have provided valuable insights into the decoding of the relationships between sequence variation and complex phenotypes, they have explained little heritability. Regional heritability mapping (RHM) provides heritability estimates for genomic segments containing both common and rare allelic effects that individually contribute too little variance to be detected by...
