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(More)
Despite the paramount importance of pineapple (Ananas comosus L.) in world production and trade of tropical fruits, the genomics of this crop is still lagging behind that of other tropical fruit crops such as banana or papaya. A genetic map of pineapple was constructed using an F2 segregating population obtained from a single selfed F1 plant of a cross A.(More)
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(More)
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(More)
Cork oak (Quercus suber L.) has a natural distribution across western Mediterranean regions and is a keystone forest tree species in these ecosystems. The fruiting phase is especially critical for its regeneration but the molecular mechanisms underlying the biochemical and physiological changes during cork oak acorn development are poorly understood.
