Cytoplasmic genomes of Jasminum sambac reveal divergent sub-mitogenomic conformations and a large nuclear chloroplast-derived insertion.

ABSTRACT:

Background

Jasminum sambac, a widely recognized ornamental plant prized for its aromatic blossoms, exhibits three flora phenotypes: single-petal ("SP"), double-petal ("DP"), and multi-petal ("MP"). The lack of detailed characterization and comparison of J. sambac mitochondrial genomes (mitogenomes) hinders the exploration of the genetic and structural diversity underlying the varying floral phenotypes in jasmine accessions.

Results

Here, we de novo assembled three mitogenomes of typical phenotypes of J. sambac, "SP", "DP", and "MP-hutou" ("HT"), with PacBio reads and the "HT" chloroplast (cp) genome with Illumina reads, and verified them with read mapping and fluorescence in situ hybridization (FISH). The three mitogenomes present divergent sub-genomic conformations, with tw
