Abstract:Six isolates of Fusarium solani f. sp. glycines that cause soybean sudden death syndrome were examined for chlamydospore formation, production, and nuclear status. Chlamydospores formed from macroconidia either terminally, laterally by outward protrusion, or intercalarily. They also formed from germinated macroconidia and hyphae. Occasionally, a single macroconidium produced more than one chlamydospore. The percentage of chlamydospores produced differed significantly (P < 0.0001) by incubation temperature and varied among fungal isolates. More chlamydospores formed at 30 C followed by 25 C, 20 C and 4 C. Nuclear stained chlamydospores usually were uninucleate but occasionally multinucleate. Nuclei migrated from macroconidia into chlamydospores through germ tubes.
