Hydra magnipapillata (now called H. vulgaris) strain 105 originated from a single polyp collected by Toshitaka Sugiyama in a swamp adjacent to the National Institute of Genetics in Mishima, Japan in September 1973. DNA for genomic sequencing was isolated from approximately 1,000 polyps of strain 105 from the laboratory of Hans Bode (University of California, Irvine). Sanger sequencing was performed at the J. Craig Venter Institute in 2010, producing an assembly with ~6x coverage and a scaffold N50 of 92.5 kb.
In 2015, DNA samples from this same strain were isolated by Rob Steele. Chicago libraries were then generated by Dovetail Genomics, with library sequencing performed by the Genomics High-Throughput Facility at the University of California, Irvine. The new assembly subsequently generated by Dovetail Genomics, called Hydra 2.0, has a scaffold N50 of ~1 MB.
