Genetic parameters for drought-tolerance in cassava

open access: yes, 2015
The objective of this work was to evaluate the effect of drought on genetic parameters and breeding values of cassava. The experiments were carried out in a completely randomized block design with three replicates, under field conditions with (WD) or ...

Estimating quantitative genetic parameters in wild populations: a comparison of pedigree and genomic approaches

open access: yesMolecular Ecology, 2014
The estimation of quantitative genetic parameters in wild populations is generally limited by the accuracy and completeness of the available pedigree information.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

open access: yesFEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

A Pedestrian Detection Method Based on Genetic Algorithm for Optimize XGBoost Training Parameters

open access: yesIEEE Access, 2019
In this paper, we present a machine learning classifier which is used for pedestrian detection based on XGBoost. Our approach, the Genetic Algorithm is introduced to optimize the parameter tuning process during training an XGBoost model.

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Estimates of genetic parameters of wood traits for sawn timber production in Eucalyptus grandis

open access: yesGenetics and Molecular Biology, 2004
In this study, the breeding perspectives of 41 open-pollinated progenies of Eucalyptus grandis were evaluated based on their wood traits. The progenies were distributed in two experiments in a randomized complete block design, with three replicates and ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions

open access: yesFEBS Letters, EarlyView.
We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

Growth Curves and Genetic Parameters in Colombian Buffaloes (Bubalus bubalis Artiodactyla, Bovidae) Curvas de crecimiento y parámetros genéticos en búfalos (Bubalus bubalis Artiodactyla, Bovidae) en Colombia Curvas de crescimento e parâmetros genéticos em búfalos (Bubalus bubalis Artiodactyla, Bovidae) na Colômbia

open access: yesRevista Colombiana de Ciencias Pecuarias, 2009
Non-linear mathematical functions proposed by Brody, Gompertz, Richards, Bertalanffy and Verhulst were compared in several buffalo production systems in Colombia. Herds were located in three provinces: Antioquia, Caldas, and Cordoba.

Componentes de (co)variância e parâmetros genéticos de características de crescimento da raça Simental no Brasil Variance components and genetic parameters estimates for growth traits of Simmental cattle in Brazil

open access: yesArquivo Brasileiro de Medicina Veterinária e Zootecnia, 1999
Informações de genealogia e produção, cedidas pela Associação Brasileira de Criadores da Raça Simental (ABCRS), relativas aos pesos desde o nascimento até um ano de idade, foram utilizadas para estimar, sob modelos alternativos, os componentes de ...
