Extracellular DNA as a Strategy to Manage Vascular Wilt Caused by in Tomato ( L.) Based on Its Action as a Damage-Associated Molecular Pattern (DAMP) or Pathogen-Associated Molecular Pattern (PAMP).
Plants (Basel)
October 2024
Article Synopsis
- - Vascular wilt is a major disease impacting tomato yields globally, caused by a specific pathogen that has developed resilience against traditional management strategies due to its ability to persist in soil and invade vascular tissues.
- - Current research is exploring plant defense mechanisms and the use of extracellular DNA (eDNA) to help tomatoes recognize and respond to disease, distinguishing between their own eDNA and that of pathogens.
- - Findings indicate that applying the eDNA of the pathogen in soil can reduce disease severity in tomatoes, enhance certain beneficial compounds, and stimulate defense gene expression, suggesting it could be a viable strategy for managing vascular wilt.
Intercropping Systems to Modify Bioactive Compounds and Nutrient Profiles in Plants: Do We Have Enough Information to Take This as a Strategy to Improve Food Quality? A Review.
Plants (Basel)
January 2024
Various environmental, food security and population health problems have been correlated with the use of intensive agriculture production systems around the world. This type of system leads to the loss of biodiversity and natural habitats, high usage rates of agrochemicals and natural resources, and affects soil composition, human health, and nutritional plant quality in rural areas. Agroecological intercropping systems that respect agrobiodiversity, on the other hand, can significantly benefit ecosystems, human health, and food security by modifying the nutritional profile and content of some health-promoting bioactive compounds in the species cultivated in this system.

- The study investigates the impact of Zinc Oxide Nanoparticles (ZnO NPs) on the Pepper huasteco yellow vein virus (PHYVV), which causes significant losses in jalapeño pepper crops in Mexico.
- Treatment with ZnO NPs showed promising results, significantly reducing symptoms and viral levels in pepper plants, especially at a concentration of 200 mM, with effects varying by treatment timing and pepper variety.
- Findings hint that ZnO NPs enhance plant resistance by altering certain enzyme levels (POD, SOD, CAT, and PAL), highlighting the potential for using nanotechnology to manage viral infections in crops.
Common bean ( L.) is an important crop for food security and for national economics for several countries worldwide. One of the most important factors of risk in common bean production is the fungal disease anthracnose caused by , which, in some cases, causes complete yield losses; this kind of plant disease is usually managed through the application of chemical products such as fungicides that are commonly not accepted by society.

Exposure to low levels of ultraviolet-B radiation (UV-B, 280-315 nm) can also activate antioxidant defenses and acclimation responses. However, how HO and UV-B interact to promote stress acclimation remains poorly understood.
