Leaves for sequencing were collected from trees in the plum repository at the Fruit Research Institute of Fujian Academy of Agricultural Sciences (Jinan District, Fuzhou, Fujian province, China).
Materials and Methods: some text to describe assembly and annotation process
Plums are temperate fruit trees, which belong to the Prunus genus in the Rosaceae family, and have been grown throughout the world for centuries.Chinese plum (Prunus salicina Lindl.) plays an important role in the global production of plum.In this study, we report the genome sequence of the Chinese plum ‘Sanyueli’, which is known to have a low-chill requirement for flower bud break. The assembled genome size was 282.38 Mb, with a contig N50 of 1.37 Mb. Over 99% of the assembly was anchored to eight pseudochromosomes, with a scaffold N50 of 34.46Mb. A total of 29,708 protein-coding genes were predicted from the genome and 46.85% (132.32 Mb) of the genome was annotated as repetitive sequence. Bud dormancy is influenced by chilling requirement in plum and partly controlled by DORMANCY ASSOCIATED MADS-box (DAM) genes. Six tandemly arrayed PsDAM genes were identified in the assembled genome. Sequence analysis of PsDAM6 in ‘Sanyueli’ revealed the presence of large insertions in the intron and exon regions. Transcriptome analysis indicated that the expression of PsDAM6 in the dormant flower buds of ‘Sanyueli’ was significantly lower than that in the dormant flower buds of the high chill requiring ‘Furongli’ plum. In addition, the expression of PsDAM6 was repressed by chilling treatment. The genome sequence of ‘Sanyueli’ plum provides a valuable resource for elucidating the molecular mechanisms responsible for the regulation of chilling requirements, and it is also useful for the identification of the genes involved in the control of other important agronomic traits and molecular breeding in plum.
Homology of the Prunus salicina Sanyueli FAAS genome v1.0 proteins was determined by pairwise sequence comparison using the blastp algorithm against various protein databases. An expectation value cutoff less than 1e-9 was used for the NCBI nr (Release 2018-05) and 1e-6 for the Arabidoposis proteins (Araport11), UniProtKB/SwissProt (Release 2019-01), and UniProtKB/TrEMBL (Release 2019-01) databases. The best hit reports are available for download in Excel format.
The Prunus salicina Sanyueli FAAS v1.0 genome gene prediction files are available in FASTA and GFF3 formats.

The Prunus salicina Sanyueli FAAS Genome v1.0 proteins were analyzed using InterProScan in order to assign InterPro domains and Gene Ontology (GO) terms. Pathways analysis was performed using the KEGG Automatic Annotation Server (KAAS).
