A comprehensive assessment of the transcriptome of cork oak (Quercus suber) thr...
Pereira-Leal, José B.; Abreu, Isabel A.; Alabaça, Cláudia S.; Almeida, Maria H.; Almeida, Paulo; Almeida, Tânia; Amorim, Maria I.; Araújo, SusanaBackground: Cork oak (Quercus suber) is one of the rare trees with the ability to produce cork, a material widely used to make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms of cork formation are still poorly understood, in great part due to the difficulty in studying a species with a long life-cycle and for which there is scarce molecular/genomic inform...
The ENU-induced powdery mildew resistant mutant pea (Pisum sativum L.) lines S(...
Santo, Tatiana; Rashkova, M.; Alabaça, Cláudia S.; Leitão, J. M.Two pea (Pisum sativum L.) powdery mildew-resistant mutant lines, S(er1mut1) and F(er1mut2), were previously obtained by experimental chemical mutagenesis with ethylnitrosourea. Identification and subsequent analysis of the genomic sequence of the PsMLO1 gene revealed one single nucleotide mutation in each mutant line that leads to either a transversion or a transition, respectively, resulting in premature stop...
The downy mildew resistance locus Pp523 is located on chromosome C8 of Brassica...
Carlier, Jorge; Alabaça, Cláudia S.; Coelho, P. S.; Monteiro, A. A.; Leitão, J. M.We have previously constructed a genetic map of Brassica oleracea L. containing the Pp523 locus that confers downy mildew resistance to adult plants. In this work, 44 SSR markers of reference for the Brassica C genome chromosomes were added to the map, allowing the nine major linkage groups to be assigned to the nine chromosomes of B. oleracea. Locus Pp523 was located on chromosome C8, and a locus determining f...
Physical mapping in a triplicated genome: mapping the downy mildew resistance l...
Carlier, Jorge; Alabaça, Cláudia S.; Sousa, N. H.; Coelho, P. S.; Monteiro, A. A.; Paterson, A. H.; Leitão, J. M.We describe the construction of a BAC contig and identification of a minimal tiling path that encompass the dominant and monogenically inherited downy mildew resistance locus Pp523 of Brassica oleracea L. The selection of BAC clones for construction of the physical map was carried out by screening gridded BAC libraries with DNA overgo probes derived from both genetically mapped DNA markers flanking the locus of...
Identificação de marcadores moleculares ligados ao gene de resistência ao míldi...
Alabaça, Cláudia S.O míldio das Crucíferas, causado pelo oomicete Hyaloperonospora Constant. parasitica (Pers. Ex Fr.) (Constantinescu e Fatehi, 2002), é uma doença que afecta a família Brassicaceae, sobretudo as espécies do género Brassica. Anteriormente, tinha sido identificada uma linha de Couve Algarvia (Brassica oleracea var tronchuda) resistente ao míldio na fase adulta cuja resistência se demonstrou ser controlada por um ú...
