Long-reads reveal that Rhododendron delavayi plastid genome contains extensive repeat sequences, and recombination exists among plastid genomes of photosynthetic Ericaceae.

ABSTRACT:

Background

Rhododendron delavayi Franch. var. delavayi is a wild ornamental plant species in Guizhou Province, China. The lack of its plastid genome information seriously hinders the further application and conservation of the valuable resource.

Methods

The complete plastid genome of R. delavayi was assembled from long sequence reads. The genome was then characterized, and compared with those of other photosynthetic Ericaceae species.

Results

The plastid genome of R. delavayi has a typical quadripartite structure, and a length of 202,169 bp. It contains a large number of repeat sequences and shows preference for codon usage. The comparative analysis revealed the irregular recombination of gene sets, including rearrangement and inversion, in the la
