Genomic analysis of the first european bacteriophages with depolymerase activity and biocontrol efficacy against the phytopathogen Ralstonia solanacearum
(2021) [Journal article]Ralstonia solanacearum is the causative agent of bacterial wilt, one of the most destructive plant diseases. While chemical control has an environmental impact, biological control strategies can allow sustainable agrosystems. ... -
Insights into the role of transcriptional gene silencing in response to herbicide-Treatments in Arabidopsis thaliana
(2021) [Journal article]Herbicide resistance is broadly recognized as the adaptive evolution of weed populations to the intense selection pressure imposed by the herbicide applications. Here, we tested whether tran- scriptional gene silencing ... -
Iron oxidation on the surface of adventitious roots and its relation to aerenchyma formation in rice genotypes
(2014) [Journal article]Com o estabelecimento da lâmina de água em lavouras de arroz irrigado, o O2 livre é consumido e o solo entra num processo de redução química mediado por microrganismos anaeróbios, alterando o ambiente onde a cultura se ... -
Is a non-synonymous SNP in the HvAACT1 coding region associated with acidic soil tolerance in barley?
(2017) [Journal article]The barley HvAACT1 gene codes for a citrate transporter associated with tolerance to acidic soil. In this report, we describe a single nucleotide polymorphism (SNP) in the HvAACT1 coding region that was detected as T-1,198 ... -
Isolamento do gene ALS e investigação do mecanismo de resistência a herbicidas em Sagittaria montevidensis
(2010) [Journal article]Diversos biótipos de sagitária (Sagittaria montevidensis Cham. & Schlecht) foram constatados como resistentes a herbicidas inibidores da enzima ALS no Brasil e em outros locais do mundo. Os objetivos deste trabalho foram ... -
Low-P tolerance mechanisms and differential gene expression in contrasting wheat genotypes
(2009) [Journal article]Os objetivos deste estudo foram determinar os mecanismos da tolerância à deficiência de P em genótipos de trigo contrastantes e avaliar a associação desses mecanismos à expressão diferenciada de genes. Foram avaliadas ... -
Natural genetic diversity of nutritive value traits in the genus Cynodon
(2020) [Journal article]The Cynodon spp. collection maintained by United States Department of Agriculture National Plant Germplasm System (USDA-NPGS) has limited information on nutritive value (NV) traits. In this study, crude protein (CP), ... -
Phenotypic variation and heritability of heading date in hexaploid oat
(2019) [Journal article]The onset of flowering is decisive to the reproductive success of plants. The objectives of this study were to characterize the phenotypic variation in heading date and estimate its heritability in segregating populations ... -
Photosynthetic light response curves in Eucalyptus benthamii and Eucalyptus dunnii clones
(2022) [Journal article]The photosynthetic light-response curve reflects the instantaneous response of the net photosynthetic rate to different gradients of photosynthetically active radiation. Genetic materials can respond differently to light ... -
Reprodução do pessegueiro : efeito genético, ambiental e de manejo das plantas
(2009) [Journal article]Há uma grande carência de pesquisas e literatura no Brasil sobre a reprodução do pessegueiro. A presente revisão de literatura aborda e confronta inúmeros resultados de pesquisas acerca dos principais fatores envolvidos ... -
Response of Arabidopsis thaliana root growth to phosphorus and its relation to media chemical composition

Seleção de alfafa (Medicago sativa L.) para tolerãncia ao alumínio em solução nutritiva
(2019) [Journal article]A alfafa (Medicago sativa L.) é uma leguminosa com alto potencial produtivo, qualidade de forragem e flexibilidade de utilização. Para a expansão desta forrageira no Brasil, torna-se necessário superar um dos maiores ... -
Target-site mutations and expression of als gene copies vary according to Echinochloa species
(2021) [Journal article]The sustainability of rice cropping systems is jeopardized by the large number and variety of populations of polyploid Echinochloa spp. resistant to ALS inhibitors. Better knowledge of the Echinochloa species present in ... -
Tetraploidization in citrus rootstocks : effect of genetic constitution and environment in chromosome duplication
(2016) [Journal article]The objective of this study was to identify polyploid plants from citrus rootstocks and to evaluate the influence of the genetic constitution and of the environment on the frequency of chromosome duplication. Populations ... -
Weed genomics : yielding insights into the genetics of weedy traits for crop improvement
(2023) [Journal article]Weeds cause tremendous economic and ecological damage worldwide. The number of genomes established for weed species has sharply increased during the recent decade, with some 26 weed species having been sequenced and de ...
