Description
Yang Liu and ten colleagues present the first chromosome-level genome of the greasyback shrimp, an Indo-Pacific species prized in fisheries and farming, in a 2026 paper. Shrimp genomes are hard to assemble because they are large, repetitive, and variable. The team combined long-read and short-read sequencing with a chromosome-contact method to scaffold the pieces.
The finished assembly spans close to two billion DNA letters, with most of the sequence anchored onto thirty-nine chromosomes. About fifty-seven percent of the genome proved to be repetitive sequence, and the shrimp's two genome copies differ noticeably from each other. Annotation found more than twenty-one thousand protein-coding genes, and a standard completeness check recovered nearly all core arthropod genes. The authors offer the resource as a base for work on shrimp evolution, coastal adaptation, and breeding.
