The ShrimpENCODE session is in memory of shrimp pathologist Dr. Donald V. Lightner (1945-2021) . The session will address the following topics: epigenetic regulation in aquatic micro-invertebrates: a non-canonical system of bacterial origin; genome sequencing and assembly strategies and comparative analysis of the genomic characteristics of P enaeid shrimp species; the genomes, epigenomes, and transcriptomes of Penaeus vannamei , P. monodon , P. japonicus , P. chinensis , and P. indicus ; 312 transposable elements characterized from the first specific pathogen-free (SPF) P. vannamei produced by the breeding program of the U.S. Marine Shrimp Farming Program (USMSFP); the complete genome of an endogenous nimavirus (Nimav-1_LVa ) integrated in the genome of SPF P. vannamei - the need for fully-assembled, contiguous reference genomes of penaeids and other crustaceans to study virus evolution and pathogenicity ; white spot syndrome virus (WSSV) from Ecuador, endogenous viral elements (EVE ) of WSSV (WSSV-EVE) and endogenous nimavirus Nimav-1_LVa : their integration in the genomes of the original SPF P. vannamei produced in the U.S. and P. vannamei farmed in China; EVEs of Decapod penstylhamaparvovirus 1 (I nfectious H ypodermal and H ematopoietic N ecrosis Virus, IHHNV) – implications for shrimp diagnosis ; P. monodon endogenous Type-A IHHNV integrated in the genomes of P. monodon from Thailand and P. vannamei from China; chromosomal locations of RTE-3_LVa a non-LTR retrotransposon identified in the first SPF P. vannamei produced in the US : a potential sex marker for shrimp; understanding of the shrimp immune response to pathogens from its transcriptome; estimation of linkage disequilibrium and effective population size in a P. vannamei population using a novel 50K SNP genotyping array ; the hurdles of delivery CRISPR-Cas9 components for gene editing in penaeid shrimps ; assessment of the oxidative stress and bio-transformation enzymatic effects of glyphosate exposure on P. vannamei ; virus interference and occurrence in crustaceans ; the NonLTR-1_LVa non-LTR retrotransposon from the first SPF P. vannamei domesticated in the USA is similar to a retrotransposon putatively associated with abdominal segment deformity disease (ASDD) of farmed P. vannamei from Thailand ; the developmental biology of penaeid shrimp ; and White Paper: the need to sequence the genomes of Penaeus Fabricius , 1798 species to confirm taxonomy classification accepted by The World Register of Marine Species (WoRMS) , among others.
Two female researchers, leaders of the genome sequencing projects of P. vannamei (Fuhua Li, China) and P. monodon (Nitsara Karoonuthaisiri, Thailand) will be recognized as 2022 ‘ Outstanding ONE HEALTH Researchers in Aquaculture’ by the Foundation for Conservation of Biodiversity (FUCOBI) of Ecuador. Twenty-two students , postdocs and research associates from twelve countries ( Belgium, Chile, China, Ecuador, Honduras, India, Mexico, Nigeria, Philippines, Romania , Thailand, United States) will be recognized as winners of the 2022 ‘Johnnie Castro Montealegre Travel Awards’ by the FUCOBI Foundation, to attend AQUACULTURE 2022.
