Weighted single-step genome-wide association analyses for milk traits in Holstein and Holstein x Jersey crossbred dairy cattle
(Elsevier, 2020-12)The purpose of this study was to identify genomic regions explaining a major proportion of the genetic variance in milk production and milk fat and protein content on a commercial herd of Holstein and Holstein x Jersey ... -
The “polyploid effect” in the breeding of aromatic and medicinal species
(Elsevier, 2020-01)The secondary metabolism of plants delivers a wide range of chemical structures with application for a vast array of activities, thus offering opportunities for social and economic development. Polyploidy is the possession ... -
Genetic variation and heteroplasmy of Varroa destructor inferred from ND4 mtDNA sequences
(Springer, 2020-02)Varroa destructor, a parasitic mite of the western honey bee, Apis mellifera L., is a serious threat to colonies and beekeeping worldwide. Population genetics studies of the mite have provided information on two mitochondrial ... -
Infestation of fruit by conspecific and heterospecific females deters oviposition in two Tephritidae fruit fly species
(Wiley, 2020-09)Tephritidae fruit fly larvae develop entirely in the host chosen by the females. To improve the fitness of their progeny, females would benefit from rejecting previously exploited hosts. Anastrepha fraterculus and Ceratitis ... -
Synthetic multi-antibiotic resistant plasmids in plant-associated bacteria from agricultural soils
(Elsevier, 2020-09)Objectives: Unlike higher organisms such as domestic animals and cultivated plants, which display a robust reproductive isolation and limited dispersal ability, microbes exhibit an extremely promiscuous gene flow and can ... -
Wolbachia pipientis associated with tephritid fruit fly pests: from basic research to applications
(Frontiers Media, 2020-06)Members of the true fruit flies (family Tephritidae) are among the most serious agricultural pests worldwide, whose control and management demands large and costly international efforts. The need for cost-effective and ... -
pBAR–H3.2, a native-optimized binary vector to bypass transgene silencing in alfalfa
(Springer, 2020-03)Alfalfa is the main forage worldwide due to its high biomass production, excellent nutritional qualities and adaptation to a wide range of environments (Singer et al. 2018). Besides, due to its ability to grow without ... -
Genetic Stability of Sexing Strains Based on the Locus swof Ceratitis Capitata
(Springer, 2002-09)This report deals with the process of improving the stability of medfly, Ceratitis capitata, genetic sexing strains (GSS) based on the swmutation on chromosome 2. This gene affects the rate of development as well as the ... -
PCR identification of petunia male sterile cytoplasm = Identificação por PCR de citoplasma macho estéril em Petunia
(Sociedade Brasileira de Floricultura e Plantas Ornamentais, 2019-12)Petunia is a very important ornamental plant with a broad range of flower colour and size, and most of the cultivars grown are propagated through seeds. Cytoplasmic male sterility (CMS) is a maternally inherited character ... -
The ammonium channel NOD26 is the evolutionary innovation that drives the emergence, consolidation, and dissemination of nitrogen-fixing symbiosis in angiosperms
(Springer, 2018-10)Increasing evidence indicates that N-fixing symbiosis has evolved several times in the N-fixing clade of angiosperms and that this evolution is driven by a single evolutionary innovation. However, the genetics of this ... -
Understanding the intracellular-to-extracellular localization switch of polyhydroxybutyrate polymerase in pseudomonas backgrounds as a microevolutionary process
(Elsevier, 2018-11)After gene duplication, paralogous genes evolve independently, and consequently, the new proteins encoded by these duplicated genes are exposed to changes in their subcellular location. Although there are increasing evidence ... -
