The complete organelle genomes of Crateva unilocularis (Capparaceae).
TL;DR
The first complete mitochondrial genome of C. unilocularis is generated using PacBio HiFi long-read sequencing, elucidating its structural organization and gene content and providing a foundation for downstream studies on phylogeny, genome architecture, and adaptive evolution in C. unilocularis and related taxa.
Abstract
OBJECTIVE Crateva unilocularis is a widely consumed woody vegetable in the family Capparaceae. This study aimed to generate and comprehensively characterize the first complete mitochondrial genome of C. unilocularis using PacBio HiFi long-read sequencing, elucidating its structural organization and gene content. We also report the complete chloroplast genome for this accession. Together, these organelle genome resources provide a foundation for downstream studies on phylogeny, genome architecture, and adaptive evolution in C. unilocularis and related taxa. DATA DESCRIPTION The chloroplast genome length of C. unilocularis is 156,525 bp, harboring 78 unique protein-coding genes (PCGs), 28 transfer RNAs (tRNAs), and four ribosomal RNAs (rRNAs). In addition, the assembly graph supports three circular mitochondrial molecules with a combined length of 566,203 bp, and junction-spanning HiFi reads validate the assembled configurations. Annotation identified 59 genes in total, including 37 PCGs, 19 tRNAs, and three rRNAs. The assembled and annotated organelle genomes represent key reference sequences for C. unilocularis within Capparaceae and will facilitate future comparative and functional genomic analyses.
