Chemometric analysis on free amino acids and proximate compositional data for selecting cowpea (Vigna unguiculata L.) diversity
Biodiversity of cowpea, along with the interesting agricultural and nutritional properties, has encouraged research with local landraces of Portugal. This work deals with the composition of dry beans of cowpea from 28 different Portuguese cultivars concerning dry matter (DM), crude proteins (CP), fat content (FC), ash, and concentration of free essential and non-essential amino acids....
Caracterização agro-morfológica de acessos de feijão-frade (Vigna unguiculata): bases para o melhoramento.
Com o objetivo de caracterizar uma coleção de 27 acessos portugueses de feijão-frade e 5 testemunhas procedeu-se à sua caracterização por parâmetros morfológicos e agronómicos com base em seis características qualitativas e onze quantitativas. in Revista de Ciências Agrárias 39, 4, pp.506-517.

Após análise duma coleção de germoplasma contendo 51 acessos de Lupinus albus, 46 de L. angustifolius, 19 de L. luteus e 10 de L. mutabilis, através de inoculações em condições artificiais, foi identificado germoplasma de L. albus e de L. angustifolius com níveis promissores de resistência, respetivamente em variedades tradicionais e em germoplasma espontâneo português....
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.
Zinc (Zn) concentration of bread wheat grown under Mediterranean conditions as affected by genotype and soil/foliar Zn application.
The combination of plant breeding and agronomic biofortification is the most reasonable approach to minimize zinc (Zn) deficiency-related problems in humans, but also in crop production. However, its efficiency and suitability under Mediterranean conditions and its effects on the grain yield and quality parameters are not well known. Field experiments were conducted over two years...
Effect of allelic variation at glutenin and puroindoline loci on bread-making quality: favorable combinations occur in less toxic varieties of wheat for celiac patients.
Genetically diverse wheat samples, twenty-seven Triticum aestivum L. varieties, grown in two environments (Portugal and Spain) were analyzed for their allelic composition in high-molecular-weight glutenin subunits (HMW-GS), low-molecular-weight glutenin subunits (LMW-GS) and puroindolines, as well as their protein content, hardness, sodium dodecyl sulfate-sedimentation (SDS-S), mixograph mixing time and breakdown resistance (MT and BDR, respectively) parameters,...

Use of the synthetic Oligo-pTa535 and Oligo-pAs1 probes for identification of Hordeum chilense-origin chromosomes in hexaploid. tritordeum.
In this study, we hybridized, for the first time, the Oligo-pTa535 and Oligo-pAs1 probes on mitotic chromosomes of hexaploid tritordeum using ND-FISH. Tritordeum (HchHchAABB) is the synthetic amphiploid resultant from crosses between wild barley (HchHch) and cultivated durum wheat (AABB). in Genetic Resources and Crop Evolution 63(6):945-951.
