Article Synopsis
- Bletilla striata, a medicinal orchid in China, is used to treat various health issues by reducing blood flow, swelling, and promoting healing.
- In June 2022 and May 2023, a root rot disease affected B. striata in Yunnan Province, with incidence rates of 16% and 17%, leading to wilting and browning of leaves and roots.
- Researchers isolated the pathogen responsible for the root rot from symptomatic plants, obtaining 10 similar fungi isolates, with one representative strain (BJG6) selected for further studies based on its distinctive colony characteristics.
Negative plant-soil feedback (NPSF) due to the buildup of soilborne pathogens in soil is a major obstacle in sustainable agricultural systems. Beneficial rhizosphere microfloras are recruited by plants, and mediating this has become a strategic priority to manipulate plant health. Here, we found that foliar infection of Panax notoginseng by Alternaria panax changed plant-soil feedback from negative to positive.
