Transcriptome analysis of growth variation in early juvenile stage of sandfish Holothuria scabra

摘要: Abstract The sandfish Holothuria scabra is a high-value tropical sea cucumber species representing major mariculture prospect across the Indo-Pacific. Advancements in culture technology, rearing, and processing present options for augmenting capture production, stock restoration, sustainable livelihood activities from hatchery-produced sandfish. Further improvements production may be gained application of genomic technologies to improve performance traits such as growth. In this study, we performed de novo transcriptome assembly characterization fast- slow-growing juvenile H. three Philippine populations. Analyses revealed 66 unigenes that were consistently differentially regulated fast-growing found associated with immune response metabolism. Further, identified microsatellite single nucleotide polymorphism markers potentially fast These findings provide insight on potential determinants underlying growth regulation early which will useful further functional studies. Highlights study explores basis variation by examining gene expression profiles stages hatchery populations using RNA-seq. Sixty-six related are several biological molecular processes, including carbohydrate binding, extracellular matrix organization, fatty-acid metabolism, metabolite solute transport. A large number category-associated SNP have been identified.
