    Understanding the genetic architecture of a quantitative trait in gymnosperms by genoty** haploid megagametophytes

    The gymnosperms are a group of plants characterized by a haploid female gametophyte (megagametophyte). With the function of bearing the female gametes and nourishing the develo** embryo, the megagametophyte ...

    Recombination rate differences for pollen parents and seed parents in Pinus pinaster

    Significantly less recombination was observed for the female gametes than for the male gametes in one individual of maritime pine (Pinus pinaster Ait.). Two segregating map** samples of the same hybrid tree wer...

    Genetic dissection of height in maritime pine seedlings raised under accelerated growth conditions

    Random Amplified Polymorphic DNAs (RAPDs) were used to investigate quantitative trait loci (QTL) for traits related to height growth on 126 F2 seedlings of maritime pine (Pinuspinaster Ait). The haploid megagamet...

    Genomic analysis in maritime pine (Pinus pinaster). Comparison of two RAPD maps using selfed and open-pollinated seeds of the same individual

    Two genomic maps were constructed for one individual tree of maritime pine, Pinus pinaster Ait., using a common set of 263 RAPD markers (random amplified polymorphic DNA). The RAPD markers were chosen from a larg...
