Asteraceae, the largest family of angiosperms, has attracted widespread attention due to its exceptional medicinal, horticultural, and ornamental value. However, conducting research on Asteraceae plants is challenging due to their complex genetic background. With the continuous advancement of sequencing technology, a vast number of genomes and genetic resources from Asteraceae species have been accumulated. This has created a demand for comprehensive genomic analysis of this diverse and expansive plant group. To address this need, we have developed the Asteraceae Genomics Database (AGD; http://cbcb.cdutcm.edu.cn/AGD/).

Currently, the AGD was established as an integrated database resource dedicated to collecting the genomic-related data of the Asteraceae family, including genomic datasets, organellar genomes, and phenotypic information. The AGD boasts a suite of useful tools, including BLAST, JBrowse, SSR Finder, HmmSearch, Heatmap, Primer3, PlantiSMASH, and CRISPRCasFinder. Users can input query sequences in FASTA format or upload a file and select a database for the search. The available BLAST options are automatically set based on the query sequence type and selected database. JBrowse can display the integrated data of three genomes and annotated genomic datasets. Users can upload their data for visualization and comparison with AGD datasets. JBrowse enables genome sequence browsing, viewing gene information, and data comparison. In addition, the SSR Finder module identifies SSRs in uploaded sequences and displays SSRs found in AGD coding sequences. HmmSearch analyzes gene families using profile-HMMs and Heatmap generates visual representations of data matrice. Primer3 can be adopted to design primers for PCR experiment, while PlantiSMASH predicts biosynthetic gene clusters in plants, and CRISPRCasFinder identifies CRISPR-Cas systems in genomes. The establishment of Asteraceae genome database is of great significance in advancing Asteraceae genomics, fostering genetic breeding, and safeguarding biodiversity.
