Project description:Prunus campanulata 'Fugui' is newly bred cultivar. Here, we report its complete chloroplast genome. The length of the P. campanulata 'Fugui' chloroplast genome is 157,948 bp, with a large single-copy region of 85,948 bp, a small single-copy region of 19,128 bp and a pair of inverted repeat regions of 26,436 bp each. The genome contains 90 protein-coding genes, 65 transfer RNA genes and 9 ribosomal RNA genes. In addition, the genome contains 67 simple sequence repeats. Phylogenetic analysis revealed that P. campanulata 'Fugui' is genetically related to previously reported P. campanulata.
Project description:The complete chloroplast genome of Cerasus campanulata was obtained by using 454 pyrosequencing technology. Cerasus campanulata chloroplast genome is 157,906 base pairs containing 115 unique genes, including 79 protein-coding genes, 39 tRNAs and eight rRNAs. Phylogenetic analysis of the protein-coding genes indicates that C. campanulata is clearly a member of the Rosaceae order.
Project description:Prunus campanulata is an important flowering cherry germplasm of high ornamental value. Given its early-flowering phenotypes, P. campanulata could be used for molecular breeding of ornamental species and fruit crops belonging to the subgenus Cerasus. Here, we report a chromosome-scale assembly of P. campanulata with a genome size of 282.6 Mb and a contig N50 length of 12.04 Mb. The genome contained 24,861 protein-coding genes, of which 24,749 genes (99.5%) were functionally annotated, and 148.20 Mb (52.4%) of the assembled sequences are repetitive sequences. A combination of genomic and population genomic analyses revealed a number of genes under positive selection or accelerated molecular evolution in P. campanulata. Our study provides a reliable genome resource, and lays a solid foundation for genetic improvement of flowering cherry germplasm.
