▶ AI Summary
The study reanalyzed 1,107 public grapevine transcriptomic datasets to build condition‑specific gene expression atlases and a whole‑genome co‑expression network associated with drought stress. A web‑based Hydric Stress Atlas App enables exploration of these resources, and network topology analysis identified candidate genes for drought tolerance that can serve as molecular markers or targets for genome editing. This work provides tools for advancing molecular breeding and sustainable viticulture under climate change.
