title: Identification of a RAPD marker linked to the pendula gene in Norway spruce (Picea abies (L.) Karst. f. pendula).
abstract: The pendula phenotype of Norway spruce [Picea abies (L.) Karst f. pendula] is characterized by narrow crowns and strong apical dominance and is controlled by a single dominant gene (P). This defined genetic control presents one of the few opportunities to map a single gene controlling a morphological trait in a forest tree. We used random amplified polymorphic DNA (RAPD) markers and bulked segregant analysis to identify one locus OPH10_720, linked to the pendula gene. The estimated recombination frequency (r) between OPH10_720 and P was 0.046 (SE r =0.032). Mapping of the pendula gene is an important first step towards the ultimate identification and cloning of this gene.
