Ecklonia radiata isolate:H140 Genome sequencing. Ecklonia radiata isolate:H140

Ecklonia radiata is a dominant kelp across much of the southern hemisphere supporting vast economic, social and ecological values. It is also of emerging interest for aquaculture industries and in blue carbon sequestration. Despite its importance, genomic resources of this key species are scant, yet could provide important knowledge to better manage, cultivate and conserve this species in our changing oceans. In this study we report the complete mitochondrial and chloroplast genomes for Ecklonia radiata. The mitochondria genome is 37,696 bp in length and contains 62 annotated genes. The plastid genome is 130,955 bp, with 175 annotated genes, and contains two large inverted repeats. Comparisons to other kelp genomes indicate that the gene sets reported here are likely complete. The recovery of two chloroplast scaffold assembly arrangements hints at the possibility of heteroplasty in E. radiata though this requires further investigation. The genomic information reported here will aid in understanding functional response of E. radiata in changing oceans, enhance the development of E. radiata as an aquaculture resource and support efforts to conserve this ecologically important marine species
