1. The rs11755527 polymorphism in the BACH2 gene and type 1 diabetes mellitus: case control study in a Brazilian population
ABSTRACT Objective Type 1 diabetes mellitus (T1DM) is an autoimmune disorder caused by a complex interaction between environmental and genetic risk factors. BTB domain and CNC homolog 2 (BACH2) gene encodes a transcription factor that acts on the differentiation and formation of B and T lymphocytes. BACH2 is also involved in the suppression of apoptosis an

4. Stability, adaptability and shelf life of Cantaloupe melon hybrids
Resumo A adoção de híbridos de melão pelo setor produtivo requer uma prévia avaliação quanto à produtividade, qualidade e vida útil pós-colheita de seus frutos. Devido as diferentes condições ambientais em que os híbridos são avaliados, espera-se que ocorra acentuada interação genótipos x ambientes e que a mesma tenha um importante papel na

5. Nitrogen management, cultivars and growing environments on wheat grain quality
RESUMO O objetivo deste estudo foi de avaliar a influência da adubação nitrogenada, do ambiente e cultivares no teor de proteínas, o volume de sedimentação com dodecil sulfato de sódio (SDSS) e no número de queda em trigo. O delineamento experimental foi em blocos ao acaso em esquema de parcelas subdivididas, em quatro repetições foram avaliadas cu

6. ADAPTABILITY AND PHENOTYPIC STABILITY OF LETTUCE CULTIVARS IN A SEMIARID REGION
RESUMO O estudo de genótipos, em diferentes ambientes ou épocas de cultivo, tem grande importância para a cultura da alface, cuja expressão do potencial produtivo é influenciada pelas condições ambientais. Deste modo, a aplicação da metodologia de modelos mistos (REML/BLUP) tem sido utilizada para avaliar os efeitos da interação genótipo x ambien

7. Genetic parameters and agronomic characterization of elite barley accessions under irrigation in the Cerrado
ABSTRACT. There is a demand for barley cultivars that are suitable for the malt industry as well as genotypes that are stable and better adapted for irrigation in the Cerrado. This study aimed to estimate the genetic parameters by assessing 69 barley genotypes from different countries, from 2012 to 2014, under irrigation in the Cerrado. Six agronomic charact

8. Phenotypic stability in cassava estimated by the AMMI analysis with supplementary genotypes
Abstract Adaptability is the yield response of cassava genotypes to environmental improvement, and stability is the predictability of this response to variations. The objective of this study was to evaluate the yield stability and adaptability of cassava varieties and clones using the AMMI (Additive Main Effects and Multiplicative Interaction) methodology an

9. Environmental stratification in cotton in the presence or absence of genotypes with high ecovalence
Abstract Cottonseed yield data of 17 genotypes, of which two genotypes contributed to more than 30% of the total ecovalence, and grown in 23 locations, were used to compare four methods of disjoint environmental stratification: a) environmental index (Ie): favorable or unfavorable environments; b) stratification in partitions that maximize the sum of squares

10. Microbial interactions: ecology in a molecular perspective
ABSTRACT The microorganism-microorganism or microorganism-host interactions are the key strategy to colonize and establish in a variety of different environments. These interactions involve all ecological aspects, including physiochemical changes, metabolite exchange, metabolite conversion, signaling, chemotaxis and genetic exchange resulting in genotype sel

11. Missing value imputation in multi-environment trials: Reconsidering the Krzanowski method
Abstract We propose a new methodology for multiple imputation when faced with missing data in multi-environmental trials with genotype-by-environment interaction, based on the imputation system developed by Krzanowski that uses the singular value decomposition (SVD) of a matrix. Several different iterative variants are described; differential weights can als

12. Factor analysis applied to the G+GE matrix via REML/BLUP for multi-environment data
Abstract The genotype x environment interaction is frequently observed in many crops and studies on environmental stratification and genotype adaptability have been proposed to understand it. The aim of this study was to carry out factor analysis in data from multi-environment experiments by the mixed model approach (REML/BLUP). Instead of adjusted phenotypi
