摘要： Chinese plum (Prunus salicina Lindl.) is a stone fruit that belongs to the Prunus genus and 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 34.46 Mb. 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, PsDAM6 expression 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.
