The HTIRDB: A resource containing a transcriptional atlas for 105 different tissues from each of seven species of domestic herbivore

Here, we describe the Herbivore Transcriptome Integrated Resource Database (HTIRDB, https://yanglab.hzau.edu.cn/HTIRDB#/). The HTIRDB comprises the self-generated transcriptomic data from 100 to 105 tissues from two female domestic herbivores from six species (cattle, donkey, goat, horse, rabbit, and sika deer) and two breeds of sheep, and an extra 28,710 related published datasets. The HTIRDB user-friendly interface provides tools and functionalities that facilitate the exploration of gene expression between tissues and species. The tools for comparative transcriptomics can be used to identify housekeeping genes, tissue-specific genes, species-specific genes, and species-conserved genes. To date, the HTIRDB is the most extensive transcriptome data resource for domestic herbivores that is freely available.
