Abstract
Initially discovered over 35 years ago in the bacterium Escherichia coli as a defense system against invasion of viral (or other exogenous) DNA into the genome, CRISPR/Cas has ushered in a new era of functional genetics and served as a versatile genetic tool in all branches of life science. CRISPR/Cas has revolutionized the methodology of gene knockout with simplicity and rapidity, but it is also powerful for gene knock-in and gene modification. In the field of marine biology and ecology, this tool has been instrumental in the functional characterization of 'dark' genes and the documentation of the functional differentiation of gene paralogs. Powerful as it is, challenges exist that have hindered the advances in functional genetics in some important lineages. This review examines the status of applications of CRISPR/Cas in marine research and assesses the prospect of quickly expanding the deployment of this powerful tool to address the myriad fundamental marine biology and biological oceanography questions.

Front Endocrinol (Lausanne) 2023; 14:1266641.

Abstract
In the culture of crustaceans, most species show sexual dimorphism. Monosex culture is an effective approach to achieve high yield and economic value, especially for decapods of high value. Previous studies have developed some sex control strategies such as manual segregation, manipulation of male androgenic gland and knockdown of the male sexual differentiation switch gene encoding insulin-like androgenic gland hormone (IAG) in decapods. However, these methods could not generate hereditable changes. Genetic manipulation to achieve sex reversal individuals is absent up to now. In the present study, the gene encoding IAG (EcIAG) was identified in the ridgetail white prawn Exopalaemon carinicauda. Sequence analysis showed that EcIAG encoded conserved amino acid structure like IAGs in other decapod species. CRISPR/Cas9-mediated genome editing technology was used to knock out EcIAG. Two sgRNAs targeting the second exon of EcIAG were designed and microinjected into the prawn zygotes or the embryos at the first cleavage with commercial Cas9 protein. EcIAG in three genetic males was knocked out in both chromosome sets, which successfully generated sex reversal and phenotypic female characters. The results suggest that CRISPR/Cas9-mediated genome editing technology is an effective way to develop sex manipulation technology and contribute to monosex aquaculture in crustaceans.

BIOLOGY 2023; 12:1331.

Abstract
Based on obtaining mstnb gene knockout in Pelteobagrus fulvidraco, a study on the effect of the mstn gene on skeletal morphology and growth was performed by comparing the number and length of the vertebrae of mutant and wild-type fish in a sibling group of P. fulvidraco, combined with the differences in cells at the level of vertebral skeletal tissue. It was found that mstnb gene knockdown resulted in a reduction in the number of vertebrae, the length, and the intervertebral distance in P. fulvidraco, and these changes may be the underlying cause of the shorter body length in mutant P. fulvidraco. Further, histological comparison of the same sites in the mstn mutant and wild groups of P. fulvidraco also revealed that the number and density of osteocytes were greater in mstnb knockout P. fulvidraco than in wild-type P. fulvidraco. Our results demonstrated that when using genome editing technology to breed new lines, the effects of knockout need to be analyzed comprehensively and may have some unexpected effects due to insufficient study of the function of certain genes.

Abstract
Disease and parasitism cause major welfare, environmental and economic concerns for global aquaculture. In this review, we examine the status and potential of technologies that exploit genetic variation in host resistance to tackle this problem. We argue that there is an urgent need to improve understanding of the genetic mechanisms involved, leading to the development of tools that can be applied to boost host resistance and reduce the disease burden. We draw on two pressing global disease problems as case studies-sea lice infestations in salmonids and white spot syndrome in shrimp. We review how the latest genetic technologies can be capitalised upon to determine the mechanisms underlying inter- and intra-species variation in pathogen/parasite resistance, and how the derived knowledge could be applied to boost disease resistance using selective breeding, gene editing and/or with targeted feed treatments and vaccines. Gene editing brings novel opportunities, but also implementation and dissemination challenges, and necessitates new protocols to integrate the technology into aquaculture breeding programmes. There is also an ongoing need to minimise risks of disease agents evolving to overcome genetic improvements to host resistance, and insights from epidemiological and evolutionary models of pathogen infestation in wild and cultured host populations are explored. Ethical issues around the different approaches for achieving genetic resistance are discussed. Application of genetic technologies and approaches has potential to improve fundamental knowledge of mechanisms affecting genetic resistance and provide effective pathways for implementation that could lead to more resistant aquaculture stocks, transforming global aquaculture.

Abstract
CRISPR/Cas9 technology has been applied to many arthropods. However, application of this technology to crustaceans remains limited due to the unique characteristics of embryos. Our group has developed a microinjection system to introduce the CRISPR/Cas9 system into Neocaridina heteropoda embryos (one-cell stage). Using the developed method, we mutated the target gene Nh-scarlet (N. heteropoda scarlet), which functions in eye development and pigmentation. The results showed that both eye color and shape were altered in individuals in which Nh-scarlet was knocked out. Furthermore, this system was also successfully applied to another decapod crustacean, Eriocheir sinensis. DNA sequencing revealed that the zoeae with red eyes had an edited version of Es-scarlet. This study provides a stable microinjection method for freshwater crustaceans, and will contribute to functional genomics studies in various decapods.

Abstract
Insulin-like peptides (ILPs) play key roles in animal growth, metabolism and reproduction in vertebrates. In crustaceans, one type of ILPs, insulin-like androgenic gland hormone (IAG) had been reported to be related to the sex differentiations. However, the function of other types of ILPs is rarely reported. Here, we identified another type of ILPs in the ridgetail white prawn Exopalaemon carinicauda (EcILP), which is an ortholog of Drosophila melanogaster ILP7. Sequence characterization and expression analyses showed that EcILP is similar to vertebrate insulin/IGFs and insect ILPs in its heterodimeric structure and expression profile. Using CRISPR/Cas9 genome editing technology, we generated EcILP knockout (KO) prawns. EcILP-KO individuals have a significant higher growth-inhibitory trait and mortality than those in the normal group. In addition, knockdown of EcILP by RNA interference (RNAi) resulted in slower growth rate and higher mortality. These results indicated that EcILP was an important growth regulator in E. carinicauda.

Abstract
The compound eye in crustaceans is a main eye type in the animal kingdom, knowledge about the mechanism to determine the development of compound eye is very limited. Paired box protein 6 (Pax6) is generally regarded as a master regulator for eye development. In the present study, a genome-based analysis of the Pax6 gene in the ridge tail white prawn Exopalaemon carinicauda was performed and two members of Pax6 homologs, named Ec-Eyeless (EcEy) and Ec-Twin of eyeless (EcToy) were identified. To understand the function of these two homologs of Pax6 gene in the prawn, the CRISPR/Cas9 genome editing technique was applied to generate EcEy and EcToy knock-out (KO) prawns and their phenotypes were analyzed. The surviving EcEy-KO embryos and larvae exhibited severe abnormal eye morphology, suggesting that EcEy is necessary for the compound eye development in prawn, while no mutant phenotype was found in EcToy-KO individuals. These findings highlighted the conservative role of Pax6 gene in the compound eye formation, and the functional differentiation between EcEy and EcToy gene may reveal a novel regulating mechanism of Pax6 on the compound eye development in the decapods. These data will provide important information for understanding the regulation mechanism for crustacean compound eye development.

Abstract
C-type lectins (CTLs) are key recognition proteins in shrimp immunity. A few years ago we reviewed sequence information, ligand specificity, expression profiles and specific functions of the shrimp CTLs. Since then, multiple integrated studies that implemented biochemical approaches using both the native and recombinant proteins, functional genetic approaches using RNA interference, and mechanistic studies by analyzing protein-protein interactions were carried out. Results from these rigorous studies revealed the functions and mechanisms of action of selected members of the shrimp CTL family. This review focuses on this new knowledge, that includes unique structural aspects, functions, and mechanisms in host-pathogen interactions, the functional relevance of regions other than the C-type lectin domain, and the regulation of transcription of shrimp CTLs. Thus, this review aims to provide a detailed update of recent studies that have contributed to our better understanding of the shrimp immune events that involve CTL functions.

Abstract
CRISPR/Cas9 technology is an efficient genome editing tool for producing genetically modified animals. Carotenoids color the world around us and their accumulation in animals could be used to culture colorful new verities in animal breeding. β, β-carotene 9', 10'-oxygenase (BCO2) is an important enzyme during β-carotene metabolism. In this research, one full-length cDNA sequence encoding BCO2 (named EcBCO2) were obtained from Exopalaemon carinicauda. The genomic structure analysis showed that EcBCO2 gene was composed of 9 exons and 8 introns. Then, the CRISPR/Cas9-mediated deletion of EcBCO2 gene was generated by co-microinjection of Cas9 mRNA and EcBCO2 sgRNA into one-cell stage embryos of E. carinicauda. Subsequently, the phenotype of EcBCO2-KO prawns was compared with that of wild-type prawns, which showed that EcBCO2-KO resulted in the color change in the hepatopancreas of prawns. In addition, the EcBCO2-KO prawns had a higher survival rate than wild-type prawns when the prawns were challenged with Vibrio parahaemolyticus or Aeromonas hydrophila. These results indicate that BCO2 gene could be used as a candidate gene in molecular marker-assistant breeding of prawns.

FISH & SHELLFISH IMMUNOLOGY 2020; 97:421-431. [PMID: 31846777 DOI: 10.1016/j.fsi.2019.12.037] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/23/2019] [Revised: 12/09/2019] [Accepted: 12/13/2019] [Indexed: 06/10/2023]
Abstract
During the immune defense reaction of invertebrate, a plenty of reactive oxygen species (ROS) could be induced to product. Though ROS can kill foreign invaders, the accumulation of these reactive molecules in animals will cause serious cell damage. Carotenoids could function as scavengers of oxygen radicals. In this research, cDNA and genomic DNA of one carotenoid isomerooxygenase gene (named EcNinaB-X1) were cloned from Exopalaemon carinicauda. EcNinaB-X1 gene was composed of 12 exons and 11 introns. EcNinaB-X1 knock-out (KO) prawns were produced via CRISPR/Cas9 technology and the change of their phenotypes were analyzed. Of the 400 injected one-cell stage embryos with cas9 mRNA and one sgRNA targeting the first exon of EcNinaB-X1 gene, 26 EcNinaB-X1-KO prawns were generated and the mutant rate reached 6.5% after embryo injection. The EcNinaB-X1-KO prawns had significant lower mortality than those in wild-type group when the prawns were challenged with Vibrio parahaemolyticus or Aeromonas hydrophila. In conclusion, we first demonstrate the function of the carotenoid isomerooxygenase gene in immune defense of E. carinicauda by performing directed, heritable gene mutagenesis.

Cloning and functional study of lipocalin: retinol-binding protein-like gene family of the ridgetail white prawn, Exopalaemon carinicauda. Mol Genet Genomics 2019; 295:453-464. [PMID: 31813041 DOI: 10.1007/s00438-019-01633-0] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Accepted: 11/29/2019] [Indexed: 10/25/2022]
Abstract
Lipocalin is a large family with complex functions including retinol-binding protein (RBP), crustacyanin (CRCN), apolipoprotein D, etc. In shrimps, it is well known that CRCN is related to body color. Recently, retinoic acid/retinol-binding protein was found in shrimp. However, little is known about the function of RBP and relationships among the gene members of lipocalin in shrimps. Based on the transcriptome sequences responding to starvation stress, three genes of the lipocalin-retinol-binding protein-like gene family (lipocalin-1, lipocalin-2, and lipocalin-3) were cloned by RACE from the ridgetail white prawn, Exopalaemon carinicauda. Homology analysis showed that these three genes had high similarity with the known insect apolipoprotein D gene and vertebrate retinol-binding protein gene, and they are of the same type in terms of evolution. Fluorescence quantitative PCR showed that the above three genes were mainly expressed in the ventral nerve cord of E. carinicauda. The expression characteristics of the three genes at different developmental stages showed that they were more highly expressed at the larval stage, which suggests that they might be related to embryonic and larval development. The RNA interference tests showed that after silencing lipocalin-1 and lipocalin-3, the body color of individual shrimps turned slightly red and the blue pigment in the epidermis largely disappeared, but no significant change took place in the appearance of individuals after silencing lipocalin-2. In addition, on the 6th and 16th days of interference, dead shrimps appeared in the lipocalin-1 and lipocalin-3 interference groups. The dead shrimps had hard crusts and remained in a molting posture. Totally, this study showed that the retinol-binding protein-like gene obtained in this study had certain biological functions in the growth and development and body color formation as CRCN; in addition, it also plays a role in nerve system and molting of E. carinicauda.

Abstract
Trehalose, a nonreducing disaccharide, is present in a wide variety of organisms and plays a key role in many organisms under different stress conditions. In the study, the full-length cDNA sequence encoding trehalose-6-phosphate synthase (EcTPS) was obtained from Exopalaemon carinicauda. The complete nucleotide sequence of EcTPS contained a 2532 bp open reading frame (ORF) encoding a putative protein of 843 amino acids. The domain architecture of the deduced EcTPS contained a glycol_transf_20 domain and a trehalose_PPase domain. EcTPS mRNA was predominantly expressed in the hepatopancreas. The expression of EcTPS in the prawns challenged with Vibrio parahaemolyticus and Aeromonas hydrophila changed in a time-dependent manner. The function of EcTPS was also studied by double-strand RNA interference. The results showed that the knock-down of EcTPS increased the mortality of the Vibrio-challenged group and Aeromonas-challenged group compared with the control group. The present study provides some new insight into the immune function of the trehalose-6-phosphate synthase in prawns.

Zhang J, Liu Y, Li Y, Su N, Zhou Y, Xiang J, Sun Y. Biological function of a gC1qR homolog (EcgC1qR) of Exopalaemon carinicauda in defending bacteria challenge. FISH & SHELLFISH IMMUNOLOGY 2018; 82:378-385. [PMID: 30144564 DOI: 10.1016/j.fsi.2018.08.046] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/30/2018] [Revised: 08/15/2018] [Accepted: 08/21/2018] [Indexed: 06/08/2023]
Abstract
The gC1qR is a ubiquitously expressed cell protein that interacts with the globular heads of C1q (gC1q) and many other ligands. In this study, one gC1qR homolog gene was obtained from Exopalaemon carinicauda and named EcgC1qR. The complete nucleotide sequence of EcgC1qR contained a 774 bp open reading frame (ORF) encoding EcgC1qR precursor of 257 amino acids. The deduced amino acid sequence of EcgC1qR revealed a 55-amino-acid-long mitochondrial targeting sequence at the N-terminal and a mitochondrial acidic matrix protein of 33 kDa (MAM33) domain. The genomic organization of EcgC1qR gene showed that EcgC1qR gene contained five exons and four introns. EcgC1qR could express in all of the detected tissues and its expression was much higher in hepatopancreas and hemocytes. The expression of EcgC1qR in the hepatopancreas of prawns challenged with Vibrio parahaemolyticus and Aeromonas hydrophila changed in a time-dependent manner. The expression of EcgC1qR in prawns challenged with V. parahaemolyticus was up-regulated at 6 h (p < 0.05), and significantly up-regulated at 12 h and 24 h (p < 0.01), and then returned to the control levels at 48 h post-challenge (p > 0.05). At the same time, the expression in Aeromonas-challenged group was significantly up-regulated at 6, 12 and 24 h. The recombinant EcgC1qR could inhibit the growth of two tested bacteria. In addition, we successfully deleted EcgC1qR gene through CRISPR/Cas9 technology and it was the first time to obtain the mutant of gC1qR homolog gene in crustacean. It's a great progress to study the biological function of gC1qR in crustacean in future.
