Revisiting the emerging pathosystem of rice sheath blight: deciphering the Rhizoctonia solani virulence, host range, and rice genotype-based resistance

Researchers studied a fungus that causes rice leaf disease in Egypt by isolating and testing different strains to understand why some were more damaging than others. They found the most aggressive strain produced more enzymes that break down plant cell walls, making it more harmful. The team also tested which rice varieties were naturally resistant to the disease and identified specific genes that could help breeders develop disease-resistant rice varieties without needing fungicide chemicals.

A Method to Inoculate Millet Grain-Colonized Fusarium pseudograminearum on Wheat to Obtain Reproducible Disease Symptoms

Scientists developed a standardized method to test wheat varieties for resistance to Fusarium crown rot, a serious fungal disease that damages wheat crops. The method uses millet grains colonized with the disease-causing fungus as inoculum, which is more reproducible and efficient than previous approaches. By testing this on wheat seedlings in controlled greenhouse conditions, researchers can quickly identify wheat varieties with natural resistance, which helps plant breeders develop better disease-resistant wheat crops.

Controlled inoculation provides insight into western redcedar resistance to multiple root- and butt-rot pathogens

Western redcedar is an economically important tree species suffering from fungal diseases that cause wood decay and significant financial losses. Researchers developed controlled methods to test how resistant young redcedar trees are to eight different decay fungi, finding that some fungi are much more damaging than others. Importantly, they discovered that some infections remain hidden without visible symptoms but still harm tree growth, and these hidden infections can be detected using advanced DNA-based methods. This research will help forest managers and breeders develop redcedar varieties with better disease resistance.
