Differential Transcriptional Regulation in Roots of Tomato Near-Isogenic Lines in Response to Rapid-Onset Water Stress.

Cultivated tomato ( L.) is susceptible to abiotic stresses, including drought and chilling stress, while its wild relative () exhibits tolerance to many abiotic stresses. Chilling roots to 6°C induces rapid-onset water stress by impeding water movement from roots to shoots.
