The serine/threonine protein kinase <i>STY13</i> gene, belonging to the protein kinase family, is one of the largest and most functionally diverse gene families, which is a critical regulatory molecule for cell function. In this study, we systematically identified and analyzed the <i>STY13</i> gene family in two major cultivated cotton species (<i>Gossypium hirsutum</i> and <i>Gossypium barbadense</i>) and their two ancestors (<i>Gossypium arboretum</i> and <i>Gossypium raimondii</i>). A total of 46, 50, 26 and 24 <i>STY13</i> genes were identified from these four species, respectively. Phylogeny analysis showed that cotton <i>STY13</i> genes (cotton STY protein kinase genes) could be classified into five groups. This gene family was evenly distributed on each chromosome in cotton. <i>STY13</i> genes contain light-responsive elements, stress-responsive elements, growth and developmental elements, and multiple gene and protein binding sites. Most motifs in the <i>STY13</i> proteins were conserved and had similar distribution patterns. However, there were some differences in specific motifs in different subfamilies. Gene expression analysis based on RNA-seq and qRT-PCR showed that <i>STY13</i> genes were responsive to abiotic stress. <i>GhSTY13-12</i> gene was located in cytoplasm. Silencing of the <i>GhSTY13-12</i> gene resulted in reduced leaf chlorosis, increased total antioxidant capacity, decreased malondialdehyde content, and enhanced drought and salt tolerance. These results provide a scientific basis for further research on the function of <i>STY13</i> in cotton and its application on cotton trait improvement.</p></div>","PeriodicalId":574,"journal":{"name":"Functional & Integrative Genomics","volume":"25 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We combined genome-wide association studies (GWAS) on amyloid endophenotypes measured in cerebrospinal fluid (CSF) and positron emission tomography (PET) as surrogates of amyloid pathology, which may provide insights into the underlying biology of the disease. We performed a meta-GWAS of CSF Aβ42 and PET measures combining six independent cohorts (<i>n</i> = 2,076). Given the opposite beta direction of Aβ phenotypes in CSF and PET measures, only genetic signals showing opposite directions were considered for analysis (<i>n</i> = 376,599). We explored the amyloidosis signature in the CSF proteome using SOMAscan proteomics (ACE cohort, <i>n</i> = 1,008), connected it with GWAS loci modulating amyloidosis and performed an enrichment analysis of overlapping hits. Finally, we compared our results with a large meta-analysis using publicly available datasets in CSF (<i>n</i> = 13,409) and PET (<i>n</i> = 13,116). After filtering the meta-GWAS, we observed genome-wide significance in the rs429358-<i>APOE</i> locus and annotated nine suggestive hits. We replicated the <i>APOE</i> loci using the large CSF-PET meta-GWAS, identifying multiple AD-associated genes including the novel <i>GADL1</i> locus. Additionally, we found 1,387 FDR-significant SOMAscan proteins associated with CSF Aβ42 levels. The overlap among GWAS loci and proteins associated with amyloid burden was minimal (<i>n</i> = 35). The enrichment analysis revealed mechanisms connecting amyloidosis with the plasma membrane’s anchored component, synapse physiology and mental disorders that were replicated in the large CSF-PET meta-analysis.
