All of the three genes were activated as the temperature decreased, and the greatest response was observed for StPSY1. StPSY3 was for the first time shown to respond to cold stress and photoperiod. A search for cis-regulatory elements was carried out in the promoter regions and 5'-UTRs of the StPSY genes, and the regulation of all three genes proved associated with the response to light. A high level of cold-induced activation of StPSY1 was tentatively attributed to the presence of cis elements associated with sensitivity to cold and ABA.</p>","PeriodicalId":11351,"journal":{"name":"Doklady Biological Sciences","volume":" ","pages":"21-26"},"PeriodicalIF":0.0,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140305163","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}

The MtHb proportion in the erythrocyte stroma was found to exceed 80% (6.20 ± 0.59 µM). Clarified hemolysates were nearly free of MtHb (0.5 ± 0.2 µM). Membrane-bound ferric hemoglobin did not affect the erythrocyte resistance to osmotic shock. The osmotic fragility range was determined using a LaSca-TM laser microparticle analyzer (BioMedSystems, Russia) to be 102-136 mOsm/kg, much the same as in other bony fish species. A nitrite load (10 mg/L) significantly increased the MtHb content in the blood.
