P.579 left column top paragraph: "Conifers contribute a large fraction of terrestrial photosynthesis and biomass, and the cultural and economic values of conifers are also paramount, early civilizations used conifers for firewood, tools and artefacts and today several national economies depend on commodities produced from conifers. However, despite their abundance and importance, [investigators'] understanding of conifer genomes is limited. Most conifers have 12 (2n = 24) chromosomes, probably reflecting the ancestral karyotype (primary source), which are typically of similar size, each being roughly comparable to the size of the human genome, and containing high proportions of repetitive elements (refs 5, 6)." |
