ERF.D2 negatively controls drought tolerance through synergistic regulation of abscisic acid and jasmonic acid in tomato.

Plants inevitably encounter a diverse array of constantly changing environmental stresses, and drought stands out as one of the most severe threats to plants. Abscisic acid (ABA) and jasmonic acid (JA) work synergistically to increase plant drought tolerance, but their interplay during drought response remains elusive. Here, we uncovered that ABA induced the degradation of a negative transcription regulator, ethylene responsive factor (ERF.

The RALF2-FERONIA-MYB63 module orchestrates growth and defense in tomato roots.

Plant secreted peptides RAPID ALKALINISATION FACTORs (RALFs), which act through the receptor FERONIA (FER), play important roles in plant growth. However, it remains unclear whether and how RALF-FER contributes to the trade-off of plant growth-defense. Here, we used a variety of techniques such as CRISPR/Cas9, protein-protein interaction and transcriptional regulation methods to investigate the role of RALF2 and its receptor FER in regulating lignin deposition, root growth, and defense against Fusarium oxysporum f.

Exogenous Rosmarinic Acid Application Enhances Thermotolerance in Tomatoes.

Due to global warming, high-temperature stress has become a major threat to plant growth and development, which causes a severe challenge to food security worldwide. Therefore, it is necessary to explore the plant bioactive molecules, which could be a promising approach to strengthening plant thermotolerance. Rosmarinic acid (RA) serves as a plant-derived phenolic compound and has beneficial and health-promoting effects for human beings.
