[Progress on whole genome sequencing in woody plants].

Abstract

In recent years, the number of sequencing data of plant whole genome have been increasing rapidly and the whole genome sequencing has been also performed widely in woody plants. However, there are a set of obstacles in investigating the whole genome sequencing in woody plants, which include larger genome, complex genome structure, limitations of assembly, annotation, functional analysis, and restriction of the funds for scientific research. Therefore, to promote the efficiency of the whole genome sequencing in woody plants, the development and defect of this field should be analyzed. The three-generation sequencing technologies (i.e., Sanger sequencing, synthesis sequencing, and single molecule sequencing) were compared in our studies. The progress mainly focused on the whole genome sequencing in four woody plants (Populus, Grapevine, Papaya, and Apple), and the application of sequencing results also was analyzed. The future of whole genome sequencing research in woody plants, consisting of material selection, establishment of genetic map and physical map, selection of sequencing technology, bioinformatic analysis, and application of sequencing results, was discussed.
