Analysis of the complete organellar genomes of the economically valuable kelp Lessonia spicata (Lessoniaceae, Phaeophyceae) from Chile

Abstract

Lessonia spicata (Suhr) Santelices is the most ecologically and economically important kelp from Pacific South America. Here, we contribute to the bioinformatics and evolutionary systematics of the species by performing high throughput sequencing on L. spicata from Valparaiso, Chile. The L. spicata complete mitogenome is 37,097 base pairs (bp) in length and contains 66 genes (GenBank accession MK965907), the complete plastid genome is 130,305 bp and has 173 genes (accession MK965908), and the data assembled 7,630 bp of the nuclear ribosomal cistron (accession MK965909). The organellar genomes are similar in structure and content to others published from the Laminariales.

Next-generation sequencing yields the complete organellar genomes of kelp Lessonia flavicans (Lessoniaceae, Phaeophyceae) from the Sub-Antarctic ecoregion of Magallanes, Chile

“…The evolutionary relationship of the generitype L. flavicans confirms that Lessoniaceae is closely allied with Laminariaceae (Tineo et al. 2019 ).…”

“…The plastid genome of L. flavicans differed from L. spicata by 1.4%. The evolutionary relationship of the generitype L. flavicans confirms that Lessoniaceae is closely allied with Laminariaceae (Tineo et al 2019).…”

“…It is A þ T biased (69.2%) and includes 45 ribosomal proteins, 27 tRNA (trnA, trnG, trnI, trnR, and trnS occur in duplicate, trnM occurs in triplicate), 27 photosystem I and II, 20 ycf, 8 cytochrome b/f complex, 8 ATP synthase, 4 RNA polymerase, 6 rRNA, and 28 other genes. The mitogenome and plastid genome of L. flavicans are similar in length, content, and organization to other Laminariales (Chen et al 2019;Tineo et al 2019;Zheng et al 2019).…”
