1. DNA replication stress: oncogenes in the spotlight
Abstract Precise replication of genetic material is essential to maintain genome stability. DNA replication is a tightly regulated process that ensues faithful copies of DNA molecules to daughter cells during each cell cycle. Perturbation of DNA replication may compromise the transmission of genetic information, leading to DNA damage, mutations, and chromoso

2. Selection of high-yielding, adapted and stable wheat lines in preliminary trials
Abstract Experimental design without replication, such as Federer's augmented block design, allows us to determine productivity, adaptability and stability in multi-environment trials. This work aimed to select productive wheat lines with high adaptability and stability in preliminary trials. The grain yield of 140 homozygous wheat lines was measured in 2015

3. 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. Association mapping of drought tolerance indices in wheat: QTL-rich regions on chromosome 4A
ABSTRACT Drought is likely the main abiotic stress that affects wheat yield. The identification of drought-tolerant genotypes represents an effective way of dealing with the continuous decrease in water resources as well as the increase in world population. The aim of this study was to identify single nucleotide polymorphisms (SNP) associated with drought to

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. Impact of high-molecular-weight glutenin alleles on wheat technological quality
Resumo: O objetivo deste trabalho foi determinar as subunidades de gluteninas de alto peso molecular (HMW-GS) e a sua relação com os parâmetros de qualidade tecnológica em uma coleção de genótipos de trigo (Triticum aestivum). Foram avaliados 272 acessos em SDS-Page, e empregados marcadores moleculares para identificação do alelo 7oe e da transloca�

8. Genetic progress, adaptability and stability of maize cultivars for value of cultivation and use trials
ABSTRACT. Maize breeding programs conduct multi-environment trials every year to assess the performance of new cultivars in pre-releasing tests. The data are combined across sites and seasons to perform a joint analysis in order to obtain information that will help breeders to select the best cultivars for different environments. Beyond this, it is essential

9. Novel molecular evidence of population structure in Anopheles (Kerteszia) bellator from Brazilian Atlantic Forest
Anopheles bellator is a primary malaria vector in the Atlantic Forest. Partial sequences of timeless and Clock genes were used to assess the genetic differentiation of five Brazilian populations, which showed strong population structure (e.g. high F ST values and fixed differences) in all pairwise comparisons between Bahia sample and the others from Paraná

10. Standardization and quality assessment for clinical grade mesenchymal stem cells from human adipose tissue
Abstract Background Mesenchymal stem cells have immense potential in stem cell-based therapies, however there is a pre-requisite to develop a curative cell dose. Adipose tissue-derived mesenchymal stem cells are promising mainly due to their potential abundance, immunomodulatory effect and remarkable differentiation potential. Nevertheless, senescence may d

12. Silicon and methyl jasmonate in the vegetative development and genetic stability of rice
ABSTRACT. Given the high demand for food worldwide, options for maximizing food production with minimum environmental impact are needed. Therefore, the objective of the present study was to evaluate the effect of silicon (Si) and methyl jasmonate (MeJA) in the vegetative development and genetic stability of rice plants, BRSMG Caravera cultivar. The treatment
