Article Synopsis
- Melatonin is a molecule found in many living organisms, and studies on its role in plants, particularly grapevines, have largely focused on its effects on growth and how it's produced, but the key genes involved in its synthesis are not fully understood.
- This study successfully cloned and identified the gene VvSNAT2 in grapevine, which encodes a protein important for melatonin production, showing optimal enzymatic activity at pH 8.8 and 45°C, and is influenced by melatonin treatment and pathogen exposure.
- Overexpressing VvSNAT2 in Arabidopsis led to increased melatonin and chlorophyll levels, improved resistance to powdery mildew, and heightened expression of salicylic acid signaling
Grape (Vitis vinifera) VvDOF3 functions as a transcription activator and enhances powdery mildew resistance.

Article Synopsis
- DOF proteins are important transcription factors in plants, influencing development and defense, but research on them in grapes is limited.
- In this study, the researchers identified and characterized a specific DOF gene, VvDOF3, from grapevine that can activate transcription and is located in the nucleus.
- The findings showed that VvDOF3 is triggered by substances and infections related to plant defense and enhances resistance to powdery mildew in Arabidopsis through the salicylic acid signaling pathway.
Article Synopsis
- Powdery mildew, caused by fungal pathogens, negatively affects grape leaves and fruits, prompting research into grape resistance mechanisms.
- The study focused on the VvTIFY9 protein, which is linked to plant stress responses, revealing its higher expression in grape leaves and its induction by salicylic acid (SA) and infection.
- Results indicated that overexpressing VvTIFY9 enhanced resistance to powdery mildew and activated defense-related genes, suggesting its key role in SA-mediated resistance in grapes.
