    查看更多>>摘要:Lycosidae females demonstrate meticulous maternal care of offspring by carrying egg sacs and juvenile spiderlings during the reproductive stage.Nuclear receptors(NRs),especially the ecdysone receptor(EcR)and ultraspiracle(USP),have attracted considerable attention in the regulation of arthropod development and reproduction due to their pivotal roles in ecdysteroid signaling cascades.In the present study,23 NRs,including one EcR and two USPs,were identified in the genome of the predatory wolf spider Pardosa pseudoannulata.RNA interference(RNAi)targeting EcR and USP-1 inhibited spiderling development and resulted in non-viable eggs in the egg sacs.EcR and USP-1 responded to changes in ecdysteroid levels,and interference in ecdysteroid biosynthesis led to similar phenotypes as dsEcR and dsUSP-1 treatments.These findings suggest that EcR/USP-1-mediated ecdysteroid signaling regulates P.pseudoannulata development and reproduction.The P.pseudoannulata females with suppressed ecdysteroid signaling proactively consumed their non-viable egg sacs,resulting in a 7.19 d shorter first reproductive cycle than the controls.Termination of the failed reproductive cycle enabled the spiders to produce a new egg sac more rapidly.This reproductive strategy may partially rescue the reduction in population growth due to non-viable eggs and compensate for the physiological expenditure of wasted maternal care,which would be beneficial for the conservation of P.pseudoannulata populations and their natural control of insect pests.

    查看更多>>摘要:The development of epigenetic maps,such as the ENCODE project in humans,provides resources for gene regulation studies and a reference for research of disease-related regulatory elements.However,epigenetic information,such as a bird-specific chromatin accessibility atlas,is currently lacking for the thousands of bird species currently described.The major genomic difference between birds and mammals is their shorter introns and intergenic distances,which seriously hinders the use of humans and mice as a reference for studying the function of important regulatory regions in birds.In this study,using chicken as a model bird species,we systematically compiled a chicken chromatin accessibility atlas using 53 Assay of Transposase Accessible Chromatin sequencing(ATAC-seq)samples across 11 tissues.An average of 50 796 open chromatin regions were identified per sample,cumulatively accounting for 20.36%of the chicken genome.Tissue specificity was largely reflected by differences in intergenic and intronic peaks,with specific functional regulation achieved by two mechanisms:recruitment of several sequence-specific transcription factors and direct regulation of adjacent functional genes.By integrating data from genome-wide association studies,our results suggest that chicken body weight is driven by different regulatory variants active in growth-relevant tissues.We propose CAB39L(active in the duodenum),RCBTB1(muscle and liver),and novel long non-coding RNA ENSGALG00000053256(bone)as candidate genes regulating chicken body weight.Overall,this study demonstrates the value of epigenetic data in fine-mapping functional variants and provides a compendium of resources for further research on the epigenetics and evolution of birds and mammals.

    查看更多>>摘要:Stearyl coenzyme A desaturase(SCD),also known as delta-9 desaturase,catalyzes the rate-limiting step in the formation of monounsaturated fatty acids.In mammals,depletion or inhibition of SCD activity generally leads to a decrease in triglycerides and cholesteryl esters.However,the endogenous role of scd in teleost fish remains unknown.Here,we generated a zebrafish scd mutant(scd-/-)to elucidate the role of scd in lipid metabolism and sexual development.Gas chromatography-mass spectrometry(GC-MS)showed that the scd-/-mutants had increased levels of saturated fatty acids C16:0 and C18:0,and decreased levels of monounsaturated fatty acids C16:1 and C18:1.The mutant fish displayed a short stature and an enlarged abdomen during development.Unlike Scd-/-mammals,the scd-/-zebrafish showed significantly increased fat accumulation in the whole body,especially in the liver,leading to hepatic mitochondrial dysfunction and severe cell apoptosis.Mechanistically,srebf1,a gene encoding a transcriptional activator related to adipogenesis,acc1 and acaca,genes involved in fatty acid synthesis,and dgat2,a key gene involved in triglyceride synthesis,were significantly upregulated in mutant livers to activate fatty acid biosynthesis and adipogenesis.The scd-/-males exhibited defective natural mating behavior due to defective genital papillae but possessed functional mature sperm.All defects in the scd-/-mutants could be rescued by ubiquitous transgenic overexpression of scd.In conclusion,our study demonstrates that scd is indispensable for maintaining lipid homeostasis and development of secondary sexual characteristics in zebrafish.

    查看更多>>摘要:Largemouth bass(Micropterus salmoides)isan economically important fish species in North America,Europe,and China.Various genetic improvement programs and domestication processes have modified its genome sequence through selective pressure,leaving nucleotide signals that can be detected at the genomic level.In this study,we sequenced 149 largemouth bass fish,including protospecies(imported from the US)and improved breeds(four domestic breeding populations from China).We detected genomic regions harboring certain genes associated with improved traits,which may be useful molecular markers for practical domestication,breeding,and selection.Subsequent analyses of genetic diversity and population structure revealed that the improved breeds have undergone more rigorous genetic changes.Through selective signal analysis,we identified hundreds of putative selective sweep regions in each largemouth bass line.Interestingly,we predicted 103 putative candidate genes potentially subjected to selection,including several associated with growth(psst1 and grb10),early development(klf9,sp4,and sp8),and immune traits(pkn2,sept2,bcl6,and ripk2).These candidate genes represent potential genomic landmarks that could be used to improve important traits of biological and commercial interest.In summary,this study provides a genome-wide map of genetic variations and selection footprints in largemouth bass,which may benefit genetic studies and accelerate genetic improvement of this economically important fish.
