Reference Nystedt B et al., The Norway spruce genome sequence and conifer genome evolution. Nature. 2013 May 30 497(7451):579-84. doi: 10.1038/nature12211 p.579 right column 3rd paragraph & p.580 table 1PubMed ID23698360
Method P.579 right column 2nd paragraph: "The availability of conifer genome sequences would enable comparative analyses of genome architecture and the evolution of key traits for seed plants, including flower or fruit development and life history (perennial versus annual), and help to determine how and why conifer genomes became so large. To address these issues and aid forest tree breeding, biodiversity and conservation studies by, for example, enabling the genome-wide design of genetic markers, [investigators] used data from massively parallel DNA sequencing to assemble a draft of the 20-Gb nuclear genome of Norway spruce (Picea abies (L.) Karst), one of the most widespread, ecologically and economically important plants in Europe. [They] analysed the protein-coding and non-coding fractions of the genome and compared them to the low-coverage draft genome assemblies of five other gymnosperms—Scots pine (P. sylvestris), Siberian fir (A. sibirica), juniper (J. communis), yew (Taxus baccata) and Gnetum gnemon—to gain insight into conifer genome evolution."
Comments P.579 right column 3rd paragraph: "[Investigators] sequenced a 43-year-old root-grafted copy of the P. abies clone Z4006, which originated from a tree in Ragunda, central Sweden, collected in 1959. Many copies of this clone are available in clone archives and seed orchards, and it has been extensively used in Swedish breeding programs. [They] estimated its genome size to be 19.6 Gb (C = 20.02 ± 0.95 pg (mean ± s.d.), Supplementary Information 1.1), in accordance with previous reports (ref 10)."
