ABSTRACT
Salvia miltorrhiza Bge. is a perennial deciduous flowering plant. Its medicinal root and rhizomes part is widely used in the treatment of various diseases. In this study, bioinformatics analysis was performed to identify 4832 genome SSR loci with length longer than or equal to 40 bp from the draft genome assembly of S. miltorrhiza. The re-sults showed that the dinucleotide repeat motifs and trinucleotide repeat motifs constitute the main types of genome SSR loci, accounting for 37.3% and 61.3% respectively. SSR types enriched with A/T bases showed significantly higher abundance than other types, including AT/TA AAT/ATT, ATA/TAT, TAA/TTA, accounting for 30.5%, 21.6%, 17.1%, 20.4% of the total number of SSR loci, respectively. 1079 primer pairs were designed for these genome SSR loci. These primers can be used for genomic diversity analysis, genetic map construction, genetic marker screening. These data could lay the foundation for population genetics and genomics research of S. miltorrhiza.
ABSTRACT
Salvia miltorrhiza Bge is a medicinal herb in traditional Chinese medicines. Until recently, dozens of compound ingredients with medicinal properties have been identified from S. miltorrhiza. Proteome analysis on medicinal ingredients synthesis mechanisms could provide a theoretical basis for S. miltorrhiza genetic improve-ment. In this study, a S. miltorrhiza specific protein/peptide sequence database was constructed using Illumina high-throughput transcriptome sequencing data of multiple types of S. miltorrhiza tissues. The database could act as a key component to carry out the proteome analysis in S. miltorrhiza.
