In this study, we analyzed the transcriptome patterns and enzymatic activities in the liver of <em>Scatophagus argus</em> following IGF3 injection. We identified 155 differentially expressed genes (DEGs), which were enriched in terms ‘retinol metabolism’, ‘steroid hormone biosynthesis’, ‘epidermal growth factor receptor tyrosine kinase inhibitor resistance’, and ‘one carbon pool by folate’ in Kyoto Encyclopedia of Genes and Genomes pathway analysis.

The combined analysis of transcriptome patterns and enzyme activities suggests IGF3 may promote energy storage and protein synthesis by the liver. These findings indicate IGF3 may support the liver to promote ovarian development and maturation in <em>S. argus.</em></p></div>","PeriodicalId":100065,"journal":{"name":"Agriculture Communications","volume":"1 2","pages":"Article 100016"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949798123000169/pdfft?md5=e0fdbef99dfa27fef34e321c7b66899b&pid=1-s2.0-S2949798123000169-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135615611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Curiously, the fact that insects are seldom the target of insecticide application is the object of frequent neglect, potentially leading to undesirable consequences. This concern is even more troubling when systemic insecticides are considered because the use of such compounds is on the rise and the popularity of preemptive seed coating with these compounds has greatly increased during the last decades. Thus, insecticide action is not limited to insects, but also affects crop plants, especially when systemic insecticides are considered. Plants are the primary target of application and venue to reach the arthropods targeted by the insecticidal molecule. Thus, they can retain and distribute insecticides and their byproducts, and eventually exhibit the consequences of such exposure. Consequently, phytotoxicity and/or bioactivation may ensue. The former response is better known although more frequently explored when herbicides are considered, while the latter is sparking more attention recently. These potential insecticide-mediated responses, particularly when systemic insecticides are considered, are here discussed individually and as a part of a biphasic continuum of response based on the hormesis phenomenon and its implications.</p></div>","PeriodicalId":100065,"journal":{"name":"Agriculture Communications","volume":"1 1","pages":"Article 100002"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49709507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, we selected a new set of 16 core SNPs and 18 core DUS traits, which exhibited higher efficiency in variety identification due to their convenient and easy processing. Moreover, the observed variations in SNP markers among each pair of tomato varieties were linearly correlated with those comparison of all different DUS traits (R<sup>2</sup> ​= ​0.85), and the linear correlation was also obtained based on the comparison of different core SNP fingerprints with those of the core DUS traits (R<sup>2</sup> ​= ​0.86).

The aim of this study was to evaluate the advantages of Bayesian threshold model and machine learning method in genomic prediction of ordered categorical traits in fish. The study was based on the analyses of simulated data and real data of Atlantic salmon. Ordinal categorical traits were simulated with varying numbers of categories (2, 3 and 4) and levels of heritabilities (0.1, 0.3 and 0.5). Linear and threshold models with BayesA and BayesCπ methods, as well as a machine learning method, support vector regression with default (SVRdef) and tuning (SVRtuning) hyperparameters were used to investigate their prediction abilities. The results showed that Bayesian threshold models yielded 2.1%, 2.6% and 2.9% higher prediction accuracies on average for 2-, 3- and 4-category traits, respectively, than Bayesian linear models. Furthermore, SVRtuning produced higher prediction accuracy compared with SVRdef and Bayesian threshold models in all scenarios. For real data, Bayesian threshold models yielded 1.2% higher prediction accuracy than Bayesian linear models, and SVRdef and SVRtuning yielded 3.3% and 6.6% higher prediction accuracies than Bayesian methods, respectively.
