摘要: Over the last decade, extensive genetic and genomic resources have been developed for conifer white spruce (Picea glauca, Pinaceae), which has one of largest plant genomes (20 Gbp). Draft genome sequences other conifers recently produced, but dense maps are needed to comprehend macrostructure, delineate regions involved in quantitative traits, complement functional investigations, assist assembly fragmented sequences. A greatly expanded P. glauca composite linkage map was generated from a set 1976 full-sib progeny, with positioning 8793 expressed genes. Regions significant low or high gene density were identified. Gene family members tended be mapped on same chromosomes, tandemly arrayed genes significantly biased towards specific classes. The integrated transcriptome data surveyed across eight tissues. In total, 69 clusters co-expressed co-localising level synteny found pine maps, should facilitate transfer structural information Pinaceae. Although current sequence remains highly fragmented, dozens scaffolds encompassing more than From these, relationship between physical distances examined genome-wide recombination rate much smaller most estimates reported angiosperm genomes. This shall large-scale next-generation provide reference resource genomics community.
