The influence of intercropping Paris polyphylla with Polygonatum cyrtonema or Ganoderma lucidum on rhizosphere soil microbial community structure and quality of Paris polyphylla

Researchers studied how planting Paris polyphylla (a rare medicinal plant) together with other plants affects soil health and medicine quality. Growing P. polyphylla alone caused problems like soil nutrient depletion and harmful microorganism growth. When grown alongside Ganoderma lucidum mushrooms or Polygonatum cyrtonema plants, the soil became healthier with better nutrients and beneficial microorganisms. This resulted in higher yields and better quality medicinal compounds in the P. polyphylla.

Rice varietal intercropping mediates resistance to rice blast (Magnaporthe oryzae) through core root exudates

Growing different varieties of rice together can help protect susceptible rice plants from blast disease. When resistant and susceptible rice varieties are planted together, the resistant plants release special chemicals from their roots that help the susceptible plants fight off the fungal disease. Scientists identified four key chemicals—azelaic acid, sebacic acid, betaine, and phenyl acetate—that work together to boost the immune system of susceptible rice plants and directly kill the blast fungus.

Maize Cultivation in Sun Mushroom Post-Harvest Areas: Yield, Soil Chemical Properties, and Economic Viability

This research shows that farmers can grow maize right after harvesting sun mushrooms, using the leftover mushroom material as natural fertilizer. This approach reduces the need for expensive chemical fertilizers while maintaining good crop yields. The system is particularly beneficial for small-scale farmers in Brazil, as it allows them to grow food year-round on the same land while saving money on fertilizer costs.

Vernicia fordii leaf extract inhibited anthracnose growth by downregulating reactive oxygen species (ROS) levels in vitro and in vivo

Researchers found that leaves from the tung tree (Vernicia fordii) contain natural compounds that effectively kill a fungus (Colletotrichum fructicola) that damages oil tea plants. The extract works by increasing harmful oxidative stress in fungal cells and turning off genes the fungus needs to survive. This explains why farmers have successfully grown these trees together for centuries to naturally reduce disease.
