Опубликована: Сен. 10, 2024

ABSTRACT Global aquaculture production has been rising for several decades, with up to 76% of the total from fish. However, problem fish diseases is becoming more and prominent in today's context pursuing sustainable aquaculture. Since first genome assembly reported 2002, genomic approaches have successfully implemented breeding enhance disease resistance reduce economic losses caused by diverse diseases. Here, we present a review current progress genomics its application disease‐resistance breeding. First, data all publicly available genomes were curated statistical analysis these performed. Subsequently, genomics‐assisted (including quantitative trait loci mapping, genome‐wide association study, marker‐assisted selection, gene transfer, editing) that applied practical disease–resistance programs are outlined. In addition, candidate genetic markers could possibly be utilized summarized. Finally, remaining challenges further directions discussed. summary, this provides insight into disease‐resistant varieties.

Origin of Polyploidy, Phylogenetic Relationships, and Biogeography of Botiid Fishes (Teleostei: Cypriniformes)

Biology, Год журнала: 2025, Номер 14(5), С. 531 - 531

Опубликована: Май 11, 2025

Botiidae is a small family of freshwater fishes distributed across Southeast Asia, South and East Asia. It comprises two subfamilies: the diploid Leptobotiinae tetraploid Botiinae. Whether species in Botiinae are autotetraploids or allotetraploids how many polyploidization events occurred during evolution this subfamily remain open questions. The phylogenetic relationships biogeography also require further investigation. In current study, we compared trees constructed using DNA sequences from mitochondrial genome five phased nuclear genes. We performed whole sequencing for species: Chromobotia macracanthus Yasuhikotakia modesta. Genome profiling botiine suggests that they likely allotetraploid origin. Nuclear gene tree topologies indicate tetraploidization only once common ancestor subfamily. Although possible maternal progenitor paternal cannot be determined, can excluded as progenitor. built study generally agree on following sister group relationships: Leptobotiinae/Botiinae, Leptobotia/Parabotia, Chromobotia/Botia, Yasuhikotakia/Syncrossus, Sinibotia/Ambastaia. Clades formed by last generic pairs sisters to each other. Timetree analyses ancestral range reconstruction suggest might have originated Asia Mainland approximately 51 million years ago later dispersed islands

Haplotype‐resolved genomes of octoploid species in Phyllanthaceae family reveal a critical role for polyploidization and hybridization in speciation

The Plant Journal, Год журнала: 2024, Номер 119(1), С. 348 - 363

Опубликована: Апрель 12, 2024

SUMMARY The Phyllanthaceae family comprises a diverse range of plants with medicinal, edible, and ornamental value, extensively cultivated worldwide. Polyploid species commonly occur in Phyllanthaceae. Due to the rather complex genomes evolutionary histories, their speciation process has been still lacking research. In this study, we generated chromosome‐scale haplotype‐resolved two octoploid ( Phyllanthus emblica Sauropus spatulifolius ) family. Combined our previously reported one tetraploid androgynus diploid cochinchinensis from same family, explored history. three polyploid were all identified as allopolyploids subgenome A/B. Each distinct groups various was uncovered independently share common ancestor (Ancestor‐AA Ancestor‐BB). Via different routes, comprising scenarios bifurcating divergence, allopolyploidization (hybrid polyploidization), autopolyploidization, they finally evolved current S. , P. respectively. We further discuss variations copy number alleles potential impacts within octoploids. addition, also investigated fluctuation metabolites medical values key factor its biosynthesis octoploids species. Our study reconstructed history these species, highlighting critical roles polyploidization hybridization processes. high‐quality provide valuable genomic resources for research evolution functional genomics.

Elongases of very-long-chain fatty acids (Elovls) are critical rate-limiting enzymes that involved in LC-PUFA biosynthesis through catalyzing the two-carbon elongation a pre-existing acyl chain. Thus far, several Elovls have been extensively studied teleost. However, functional and physiological roles chondrichthyans rarely reported. In this study, we identified characterized

Metabolomics in sturgeon research: a mini-review

Fish Physiology and Biochemistry, Год журнала: 2024, Номер 50(4), С. 1895 - 1910

Опубликована: Июль 9, 2024

Abstract Sturgeons are ancient fish, with 27 species distributed in the Northern Hemisphere. This review first touches upon significance of sturgeons context their biological, ecological, and economic importance, highlighting status as “living fossils” challenges they face genomic research due to diverse chromosome numbers. then discusses how omics technologies (genomics, transcriptomics, proteomics, metabolomics) have been used sturgeon research, which so far has only done on Acipenser species. It focuses metabolomics a way better understand work react environment. Specific studies cited, showing investigate various aspects biology, such growth, reproduction, stress responses, nutrition. These demonstrate potential improving aquaculture practices conservation efforts. Overall, suggests that metabolomics, relatively new scientific tool, enhance our understanding biology aid sustainable aquaculture, contributing global food security

findGSEP: Estimating genome size of polyploid species using k-mer frequencies

Bioinformatics, Год журнала: 2024, Номер 40(11)

Опубликована: Окт. 30, 2024

Estimating genome size using k-mer frequencies, which plays a fundamental role in designing sequencing and analysis projects, has remained challenging for polyploid species, i.e., ploidy p > 2. To address this, we introduce "findGSEP," is designed based on iterative curve fitting of frequencies. Precisely, it first disentangles up to normal distributions by analyzing frequencies whole the focal species. Second, computes sizes genomic regions related 1∼p (homologous) chromosome(s) each respective fitting, from infers full average haploid size. "findGSEP" can handle any level p, infer more accurate than other well-known tools, as shown tests simulated real data various species including octoploids.
