(Aug 26, 2025): A sum of 4,105 new QTL/associations have been curated into the database. (New additions less obsolete/retracted ones: Cattle: 642; Chicken: 212; Goat: 0; Horse: 9; Pig: 371; Sheep: 2,871; Rainbow trout: 0 -- Net increase: 4,105). To date, the current total number of QTL in the database: 296,528 [Breakdown by species -- Cattle: 194,095 (on 558 traits); Chicken: 29,328 (on 243 traits); Goat: 2,713 (on 90 traits); Horse: 2,491 (on 71 traits); Pig: 57,412 (on 410 traits); Sheep: 8,288 (on 182 traits); Rainbow trout: 2,201 (on 35 traits)] curated from 2,991 publications.
( This is a joint release with the 25th CorrDB release.)

In addition, our efforts on keeping data quality since the last release have involved 3,385 QTL, 1,399 base traits and 3,901 trait variants.

Database developments notes:
(1) A new set of curation tools to tag tissue information has been developed to allow animal tissues be identified where applicable, and unambiguously linkable to related database resources involving expression studies, functional annotations, etc. This tool set has included an animal tissue vocabulary collection and maintenance tool (started with Uberon and Brenda tissue ontologies, it currently has 1600+ active terms), a curation portal to allow adding or excluding terms, an automated keyword tagging pipeline to pre-compute possible tissue tags, and a curator confirmation and edit interface to finalize the results. (2) Miscellaneous debugs and web interface adjustments to improve data search. (3) Curation pipeline tuning in terms of data status tracking, monitoring, and report on web portals. For example, a weekly updated number of newly curated (pre-release) data counts can be seen along with other data summaries ("Data in Curation Pipeline") for each species.
