▶ AI Summary
Foliar application of Trichoderma harzianum cell‑free culture filtrates enhanced fruit yield, root growth, and photosynthesis in a commercial tomato cultivar under long‑term water deficit. Systems‑level analysis showed that the filtrate largely prevented drought‑induced transcriptional changes, suppressing about half of water‑stress responsive genes, thereby improving tolerance to water scarcity.
