A engenharia genética Genetic engineering [PDF]

open access: yesRevista de Saúde Pública, 1991
São abordados os progressos havidos com as técnicas de engenharia genética, capazes de alterar o potencial genético de um organismo, quer pela introdução, quer pela supressão de novos genes estruturais.

Drought tolerance classification using unmanned aerial systems based on RGB and multispectral data [PDF]

open access: yesFrontiers in Plant Science
Drought poses a global threat to food security and demands intensified efforts from breeding programs. Yet the lack of efficient methods for selecting this trait increases the cost and time required to develop new cultivars.

Lysine α-ketoglutarate reductase as a therapeutic target for saccharopine pathway related diseases [PDF]

open access: yesFrontiers in Molecular Neuroscience
The saccharopine pathway (SacPath) and the pipecolate pathway (PipPath) catabolize lysine to α-aminoadipate. Although the PipPath has been highlighted as the prominent route operating in the brain, recent work has demonstrated that the SacPath plays a ...

Enabling genome editing in tropical maize lines through an improved, morphogenic regulator-assisted transformation protocol [PDF]

open access: yesFrontiers in Genome Editing, 2023
The recalcitrance exhibited by many maize (Zea mays) genotypes to traditional genetic transformation protocols poses a significant challenge to the large-scale application of genome editing (GE) in this major crop species.

Adaptive evolution of electron transfer pathways in Thermoanaerobacterium saccharolyticum [PDF]

open access: yesJournal of Bacteriology
Thermoanaerobacterium saccharolyticum is an anaerobic, thermophilic bacterium that has been proposed for use in consolidated bioprocessing in coculture with cellulolytic bacteria such as Clostridium thermocellum for ethanol production. Although the mixed

Can a Top Predator Persist After One of the World's Largest Mining Dam Failures? Occupancy Dynamics of the Neotropical Otter in Brazil's Paraopeba River. [PDF]

open access: yesEcol Evol
We evaluated the effects of the 2019 Brumadinho tailings‐dam collapse on neotropical otters (Lontra longicaudis) in Brazil's Paraopeba river using multi‐season occupancy models. Six years post‐collapse, otters showed high occupancy across impacted reaches.

Genetic Parameter Estimation for Pregnancy Loss and Their Association With Reproductive and Growth Traits in Brahman Cattle Under Extensive Tropical Conditions. [PDF]

open access: yesJ Anim Breed Genet
ABSTRACT This study estimated genetic parameters for pregnancy loss (PL) in Brahman cattle and evaluated the genetic correlation of PL with growth and reproductive traits using both the pedigree relationship matrix (A) and pedigree plus genomic relationship matrix (H). Data were collected from two herds in Bolivia, focusing on three age groups: heifers,

Soil Microbiome of Tropical Seasonal and Permanent Small Wetlands. [PDF]

open access: yesEnviron Microbiol Rep
Distinct hydrological regimes shape microbial communities and metabolic pathways in tropical wetlands. Redox‐driven shifts highlight enhanced methanogenesis under anoxia, and dominant archaeal and bacterial groups reflect specific redox conditions and adaptations, with important implications for biogeochemical cycling and climate‐relevant processes ...

Bioética e eugenia: pressupostos biopolíticos da manipulação genética

open access: yesGriot, 2022
A partir da hipótese de que seres humanos modificados terão projetos de vida bem sucedidos, reflete-se quais seriam os pressupostos biopolíticos da manipulação genética na sociedade moderna. Considerando as teorias apresentadas por Michel Foucault (2005)
