Abstract Genetic maps of random amplified polymorphic DNA (RAPD), fragment length polymorphisms (AFLP) and inter simple sequence repeats (ISSR) markers in pineapple (2n = 2x 50) are reported for the first time. On basis a segregating population 46 F1 individuals from cross Ananas comosus x A. bracteatus , genetic these two species were constructed using two‐way pseudo‐testcross approach. The map consists 335 (60 RAPDs, 264 AFLPs 11 ISSRs) assembled into 50 linkage groups, 26 them with at...

Cork oak (Quercus suber) is one of the rare trees with ability to produce cork, a material widely used make wine bottle stoppers, flooring and insulation materials, among many other uses. The molecular mechanisms cork formation are still poorly understood, in great part due difficulty studying species long life-cycle for which there scarce molecular/genomic information. forests ecological importance represent major economic social resource Southern Europe Northern Africa. However, global...

Abstract The Lupinus genus includes a number of important crop species. use defined nucleotide sequences for the analysis genetic diversity among these species has revealed modest levels diversity. aim this study was to access AFLP, ISSR and RAPD markers evaluate L. albus, angustifolius, cosentinii, hispanicus, luteus, mutabilis, pilosus polyphyllus. Unexpectedly, low similarity were found (ranging from 0.205 0.432), regardless type molecular marker used. Nevertheless, techniques...

With 2 figures and 1 table Abstract 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 reference for C genome chromosomes were added map, allowing nine major linkage groups be assigned B. . Locus was located on chromosome C8, determining flower colour mapped C3. comparison with first version new is denser more compact. The available genomic information enriched...

Cork oak (Quercus suber L.) has a natural distribution across western Mediterranean regions and is keystone forest tree species in these ecosystems. The fruiting phase especially critical for its regeneration but the molecular mechanisms underlying biochemical physiological changes during cork acorn development are poorly understood. In this study, transcriptome of acorn, including seed, was characterized five stages development, from early to maturation, identify dominant processes each...

After binding to target membranes, hemolysin resisted elution with EDTA, salt or solutions low ionic strength hence resembled an integral membrane protein.

Strawberry tree (Arbutus unedo L.), an evergreen shrub/small of the family Ericaceae, is a main constituent Mediterranean basin flora; although it also found in southwestern France, Macaronesia, and Ireland. The small fruits are edible but mostly used for preparation preserves jams, liquors such as Portuguese traditional "aguardente de medronho". Traditionally cultivated by farmers, often consociation with Quercus sp., strawberry presently emerging new important fruit crop large orchards...
