Biochemical, physiological and genetic analysis of aluminum tolerance of different rye species.
Rye (Secale cereale L.) is one of the most Al-tolerant cereal with a valuable genetic background for breeding purposes. Wild relatives (Secale spp.) have great importance once they can provide new sources of genes related to this trait. Different cellular disorders possibly related to Al tolerance/toxicity were observed through histochemical root staining methods in cultivated...
Aluminum tolerance in Secale species: genetic diversity, molecular mechanisms and gene characterization
Tese de Doutoramento de Elisabete Cristina Jesus dos Santos.
Characterization, genetic diversity, phylogenetic relationships, and expression of the aluminum tolerance MATE1 gene in Secale species.
The cDNA sequences, phylogenetic relationships, Al-tolerance, citrate exudation, and expression of the ScMATE1 gene were analyzed in several cultivars and wild species/subspecies of the Secale genus. in Biol Plant. 62 (1):109–120. Leia o trabalho completo aqui.
Molecular diversity and genetic relationships in Secale.
The objective of this study was to quantify the molecular diversity and to determine the genetic relationships among Secale spp. and among cultivars of Secale cereale using RAPDs, ISSRs and sequence analysis of six exons of ScMATE1 gene. in Journal of Genetics. 95(2): 273-81.

Oxidative Metabolism of Rye (Secale cereale L.) after Short Term Exposure to Aluminum: Uncovering the Glutathione-Ascorbate Redox Network.
At early development stages the underling physiological and biochemical mechanisms to tolerate Al passes through modulation of ascorbate–glutathione enzymes, essentially MDHAR and DHAR in a genotype-dependent manner. in Frontiers in plant science 7: 685. Leia o trabalho completo aqui.

Al toxicity mechanism in tolerant and sensitive rye genotypes.
Rye (Secale cereale L.) plants have high tolerance to Al, and become unique tools to study Al-toxicity and tolerance mechanisms. To better understand if and how Al-induced root growth inhibition is related with root histological differentiation, nutrient balances and cell cycle dynamics, tolerant (AT6) and sensitive (AS6) rye lines were exposed for 24 h to...
Efeito de diferentes tipos de adubos azotados na cultura da cevada dística
Tese de Licenciatura
A importância da avaliação agronómica e qualitativa de cevada dística para malte na elaboração da Lista de Variedades Recomendadas.
O objetivo dos produtores portugueses de cerveja vai no sentido de depender cada vez menos da importação de malte, apostando no abastecimento de cevada dística produzida em Portugal. Por isso, a identificação de variedades com elevado potencial agronómico e qualidade tecnológica para o fabrico de malte e cerveja apresenta-se como a melhor forma de garantir...
