Insights into the nuclear-organelle DNA integration in Cicuta virosa (Apiaceae) provided by complete plastid and mitochondrial genomes.

ABSTRACT:

Background

Gene transfer between the organelles and the nucleus plays a central role in shaping plant genome evolution. The identification and analysis of nuclear DNA of plastid (NUPTs) and mitochondrial (NUMTs) origins are important for exploring the extent of intracellular DNA transfer in genomes.

Results

We report the complete plastid and mitochondrial genomes (plastome and mitogenome) of Cicuta virosa (Apiaceae) as well as a draft nuclear genome using high-fidelity (HiFi) PacBio sequencing technologies. The C. virosa plastome (154,449 bp) is highly conserved, with a quadripartite structure, whereas the mitogenome (406,112 bp) exhibits two chromosomes (352,718 bp and 53,394 bp). The mitochondrial-encoded genes (rpl2, rps14, rps19, and sdh3) were successfully transferred t
