???displayArticle.abstract???
The Alliance of Genome Resources (Alliance) is an extensible coalition of knowledgebases focused on the genetics and genomics of intensively-studied model organisms. The Alliance is organized as individual knowledge centers with strong connections to their research communities and a centralized software infrastructure, discussed here. Model organisms currently represented in the Alliance are budding yeast, C. elegans, Drosophila, zebrafish, frog, laboratory mouse, laboratory rat, and the Gene Ontology Consortium. The project is in a rapid development phase to harmonize knowledge, store it, analyze it, and present it to the community through a web portal, direct downloads, and APIs. Here we focus on developments over the last two years. Specifically, we added and enhanced tools for browsing the genome (JBrowse), downloading sequences, mining complex data (AllianceMine), visualizing pathways, full-text searching of the literature (Textpresso), and sequence similarity searching (SequenceServer). We enhanced existing interactive data tables and added an interactive table of paralogs to complement our representation of orthology. To support individual model organism communities, we implemented species-specific "landing pages" and will add disease-specific portals soon; in addition, we support a common community forum implemented in Discourse. We describe our progress towards a central persistent database to support curation, the data modeling that underpins harmonization, and progress towards a state-of-the art literature curation system with integrated Artificial Intelligence and Machine Learning (AI/ML).

	Figure 2. Paralog table for C. elegans hlh-25.The table presents a ranking of paralogs for the hlh-25 gene, based on a weighted scoring algorithm that incorporates sequence conservation metrics. It lists the gene symbols, provides the alignment length in amino acids, and quantifies the similarity and identity percentages of genes paralogous to hlh-25. The methodology count, indicating the number of algorithms supporting the paralogous relationship, is also included. In this ranking, hlh-27 is identified as the primary paralog due to its high similarity and identity scores, despite being recognized by fewer methods than hlh-28.

	Figure 4. Screenshot of results from the Alliance SequenceServer BLAST tool.The results have been enhanced relative to the default Sequence Server results page by the addition of links to Alliance JBrowse and to the corresponding gene page (in this case, C. elegans abi-1) at the Alliance website for each BLAST hit.
	Figure 5. Output of a BLAST searchAfter a user clicks on the JBrowse link for a BLAST hit they are directed to the web service where they will see a track for the BLAST hit and how the hit aligns with other tracks.
	Figure 6. AllianceMine example.Using a simple template, a disease ontology (DO) term is chosen, and all genes associated with this DO term are returned in a downloadable table.
	Figure 7. Alliance Pathway Viewer.The pathway widget displays gene products (light purple rectangles), protein complexes (light grey rectangles) and chemicals (light blue rectangles) and the flow of information and material between them (relations). These relations, shown in legend indicate direct or indirect regulation that can be positive, negative or of unknown effect direction.
