RNA-seq revealed functional differences in sensory ability and sperm-egg recognition between right and left eyestalks, with cephalic tentacles displaying asymmetry in cytoskeletal organization and cell cycle regulation. Epipodial tentacles showed similar asymmetries, including immune response differences. Moreover, the cAMP-protein kinase A (PKA)-CREB-binding protein (CBP) signaling pathway responded asymmetrically, with PKA responding to activators and inhibitors on both sides and CBP showing a stronger response on the right. These findings provide insights into sensory asymmetry in mollusks and guidance for further investigations of the molecular mechanisms underlying asymmetry in symmetrical organs.","PeriodicalId":93949,"journal":{"name":"Comparative biochemistry and physiology.

In addition, we sequenced the transcriptome of skin and brain tissues of H. yunnanensis exposed to 12 °C (cold), 20 °C (cool), 28 °C (warm), and 36 °C (hot). The results showed that a total of 591 TRPs were identified in the genomes of 21 Squamate species, and these genes were classified into six subfamilies. Among them, 26 TRP genes were identified in H. yunnanensis and distributed on 13 chromosomes. Overall, TRP genes were conserved in squamates. Based on the transcriptome results, we found a total of 9 TRP genes expressed in the brain and skin of H. yunnanensis, of which six TRP genes were under positive selection. TRPP1L2, TRPP1L3, and TRPV1 were involved in heat-sensitive responses (> 36 °C), and TRPV3, TRPA1, and TRPM8 were involved in cold-sensitive responses (< 20 °C).

Totally, 2663 DEGs and their set modules significantly related to spermatogenesis were obtained using WGCNA, including 40 candidate genes represented by EVM713. The gene was specifically expressed in the testis. RNA interference (RNAi) of EVM713 led to impaired testis development, marked by sparse sperm cell arrangement, spermatocytes detaching from the follicle wall, and reduced spermatocyte numbers. Meanwhile, 24 h after RNAi, the expression levels of Bax, and Caspase3 significantly increased (P < 0.05), while those of Bcl2, Dmrt2 and Tssk4 were significantly decreased (P < 0.05). These results indicate that EVM713 is essential for spermatogenesis in bivalves, regulating testis development through the modulation of Dmrt2 and Tssk4 expression.

This study presents a genome-wide analysis of the UGT gene family in the brown planthopper, Nilaparvata lugens, a destructive insect pest of rice in Asia. Based on the similarity to UGT homologs from other organisms, 20 putative NlUGT genes were identified in N. lugens. Sequence analysis revealed an average amino acid identity of 45.64 %; however, catalytic and sugar-binding residues, along with UGT signature motifs, were highly conserved. Phylogenetic analysis showed that the 20 NlUGTs were clustered into three main groups. The motif numbers ranged from 5 to 10, with motifs 1 and 4 being found in the functional domains of all 20 NlUGT proteins. Tandem and segmental duplication analysis identified one tandem duplication pair (UGT386K7 and UGT386K8) and two pairs of collinearity genes (UGT362C6/UGT386J4 and UGT386C2/UGT386G5) that expanded through segmental duplication within the UGT gene family of N. lugens. Combining the transcriptome and real-time quantitative PCR data showed that gut, antennae, integument, and ovaries were the tissues enriched with NlUGT gene expression. Six NlUGTs were present mainly in the gut, suggesting their putative roles in detoxification. This research provides valuable information on the molecular and genetic basis of NlUGTs, establishing a solid foundation for subsequent functional investigations of UGTs in planthopper, as well as paving the way for identifying potential targets to manage N. lugens effectively.","PeriodicalId":93949,"journal":{"name":"Comparative biochemistry and physiology.

At a salinity of 80 ppt, 100 % of females produced diapaused cysts, compared to 20 % at 50 ppt. Metabolic profiling revealed significant alterations in a range of metabolites, including 5,6-dihydrouracil, betaine, and malate, in females undergoing oviparity at 80 ppt compared to ovoviviparity at 30 ppt. Multivariate statistical analyses indicated clear separation between the two reproductive strategies. The up-regulated metabolites in oviparity were involved in significant metabolic pathways, such as β-alanine metabolism and the citrate cycle, highlighting substantial metabolic differences between the two reproductive strategies. These identified metabolic pathways might play crucial roles in the maternal response to high salinity, facilitating embryo protection and enhancing the survival and reproductive success of brine shrimp.

The dimorphic expression pattern of most sox genes in intersex and adult gonads was also observed, suggesting an important role of sox genes for sex differentiation in P. leopardus. Notably, sox32 was specifically highly expressed in gonadal tissues and might play a novel role within the gonads.

This species has successfully adapted to shallow-water conditions in paddy fields. To reveal the adaptation mechanism, we conducted transcriptome sequencing on the hepatopancreas of PF-carp under two temperature conditions (28 °C and 38 °C) and concurrently analysed RNA-seq data from hypoxic conditions in the same tissue. By analysing high-temperature transcriptome data, 3154 differentially expressed genes (DEGs) were identified. KEGG analysis indicated that DEGs involved various pathways, including protein processing in endoplasmic reticulum, circadian rhythm, and HIF-1 signaling pathway. Notably, protein processing in endoplasmic reticulum was significantly enriched with key genes such as HSP70, HSP90, HSP40, CNX, CRT, and Bip. Through concurrent analysis of RNA-seq data from hypoxic conditions, we found that PF-carp regulate their metabolism through multiple pathways and produce almost opposite metabolic regulation to adapt to high temperature and hypoxic environments. The opposite activation state observed in the HIF-1 signaling pathway is particularly intriguing. In conclusion, PF-carp appear to rely on protein processing in endoplasmic reticulum to maintain cell homeostasis at high temperatures. The HIF-1 signaling pathway may emerged as a key player in adapting PF-carps to paddy fields.

As a significant species in aquaculture, Lateolabrax japonicus serves as an exemplary model for investigating these interactions and their subsequent effects on growth and health. This study utilized a multi-omics approach, incorporating metagenomic sequencing and non-targeted metabolomics, to delineate the gut microbiota and metabolome of L. japonicus throughout various developmental phases. Collected from a meticulously controlled aquaculture setting, the intestinal microbiota of L. japonicus underwent high-throughput sequencing to scrutinize microbial DNA and enumerate metabolites. The metagenomic analysis uncovered a heterogeneous gut microbiota in L. japonicus, predominantly composed of Proteobacteria and Firmicutes, with marked heterogeneity in microbial composition across developmental stages. A particularly noteworthy discovery was the prevalence of the genus Acinetobacter, which may significantly influence health and disease resistance. The metabolomic profiling discerned 4479 metabolites, each exhibiting pronounced stage-specific metabolic signatures, particularly within lipid, amino acid, and energy metabolism pathways. The correlation analysis between microbiota and metabolites highlighted the substantial impact of specific genera, such as Acinetobacter and Gaeumannomyces, on the metabolic milieu. This study provides a comprehensive overview of the dynamic shifts in the gut microbiota and metabolome of L. japonicus, highlighting stage-specific transitions that could be pivotal for refining aquaculture practices. The findings underscore the complex interdependence between microbiota composition and metabolic function, providing valuable insights into the modulation of fish health and growth.","PeriodicalId":93949,"journal":{"name":"Comparative biochemistry and physiology.
