Early identification of plant fungal diseases is critical for timely treatment, which can prevent significant agricultural losses. While molecular analysis offers high accuracy, it is often expensive and time-consuming. In contrast, image processing combined with machine learning provides a rapid and cost-effective alternative for disease diagnosis.

- The study focused on identifying beneficial endophytic fungi from five medicinal plants and their effects on maize seed germination.
- Researchers isolated 97 endophytic fungi from samples and discovered that certain species, such as Alternaria consortiale, significantly improved seed germination and maize growth.
- Findings suggest that these fungi, particularly from high-altitude areas, could serve as biofertilizers, potentially reducing the need for chemical fertilizers in agriculture.
Background: blotch (STB) caused by fungus , is one of the important wheat ( L.) diseases difficult to control because of the lack of wheat resistant cultivars. The use of biological control agents is one possible way for triggering host plant resistance to biotic and abiotic stresses.

Thomson's leaves, respectively, reduced N-acyl homoserine-based quorum sensing in bioindicator strain Pseudomonas syringae pv.
View Article and Find Full Text PDFL-asparaginase is an important anticancer enzyme that is used in the first line treatment of acute lymphoblastic leukemia. This study was conducted to isolate L-asparaginase-producing endophytic fungi from medicinal plants of family Asteraceae. Seven healthy medicinal plants from family Asteraceae were selected for the isolation of endophytic fungi using standard surface sterilization techniques.

- Poplar chips were treated with the fungus Trametes versicolor for different durations (1, 2, and 3 weeks) to enhance kraft pulping effectiveness.
- The treatment led to the degradation of lignin and carbohydrates, improving pulp characteristics such as fiber length and reducing fine fiber content.
- The optimal duration for pre-treatment was identified as 2 weeks, which yielded the best balance of fiber length and quality for kraft pulping.
