MIGS Eukaryotic sample from Alternaria alternata
Alternaria alternata
The fungal isolate H91 (Alternaria alternata) was obtained from leaf spots of Poacynum hendersonii (Hook. f.) Woodson in Xinjiang, China, in June 2024. The sample was isolated using single-spore isolation on potato dextrose agar (PDA) at 25 C, and confirmed as A. alternata by morphological and molecular (Alta1, APM, ATP, Calmodulin, PGS1) methods. The disease symptoms include necrotic lesions with dark margins, chlorosis, and premature leaf abscission, resulting in significant yield losses. Our findings will inform targeted management practices, including resistant cultivar selection and fungicide application protocols.
