1. Cytogenetic mapping of the ALMT (aluminum-activated malate transporter) gene in wheat genotypes
ABSTRACT: Presence of the ALMT1 (aluminum-activated malate transporter) gene confers resistance to aluminum toxicity in Triticum aestivum (common wheat). No resistant cultivars of Triticum turgidum ssp. Durum Desf. (durum wheat) have been registered in Brazil. The aim of this study was to map the ALMT1 through application of the FISH (fluorescence in situ hy

2. Transportadores de ácidos orgânicos na tolerância ao alumínio tóxico em trigo
RESUMO: A toxicidade do alumínio (Al) às plantas é observada em cerca de 15% dos solos no planeta, sendo um fator restritivo à produtividade em terras cultiváveis. No Brasil, os solos ácidos são limitantes à produção de trigo (Triticum aestivum L.) e outros cereais. O Al é tóxico para a maioria dos cereais de inverno, quando a sua concentração

3. Initial root length in wheat is highly correlated with acid soil tolerance in the field
ABSTRACT: In acid soils, toxic aluminum ions inhibit plant root growth. In order to discriminate aluminum (Al) tolerance, trustful screening techniques are required. In this study, 20 wheat cultivars, showing different levels of Al tolerance, were evaluated in a short-term soil experiment to access their relative root length (RRL). Moreover, the alleles of t

5. Low-P tolerance mechanisms and differential gene expression in contrasting wheat genotypes.
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 plântulas das cultivares de trigo Toropi (tolerante à deficiência de P) e Anahuac (sensível). As plântulas foram cultivadas em hi

7. Genetic transformation of Sorghum bicolor (L. Moench) aiming Al+3 tolerance / TransformaÃÃo genÃtica de Sorghum bicolor (L. Moench) visando tolerÃncia ao AlumÃnio.
The genetic transformation has been frequently associated with conventional genetic breeding programs. This technique allows the introduction of exogenous gene(s) into plant genomes, modifying specific characteristics. It can be an important supplementary tool for sorghum conventional breeding programs. However, most of the genetic transformation protocols r

8. Characterization and utilization of genes involved with aluminum tolerance in maize / Caracterização e utilização de genes envolvidos na tolerancia ao aluminio toxico em milho
Acid soils are found worldwide but most of them are located in tropical and subtropical regions. Aluminum (Al), the most abundant metal on the earth surface, becomes soluble in the soil solution as consequence of low pH in acid soils and achieves phytotoxic levels for most of the cultivated plant species. The first symptom of Al toxicity is the inhibition of

9. Engineering high-level aluminum tolerance in barley with the ALMT1 gene
Acidity is a serious limitation to plant production on many of the world's agricultural soils. Toxic aluminium (Al) cations solubilized by the acidity rapidly inhibit root growth and limit subsequent uptake of water and nutrients. Recent work has shown that the ALMT1 gene of wheat (Triticum aestivum) encodes a malate transporter that is associated with malat
