This paper explores the genetic basis of the ability of the fungus, Ustilago maydis, to induce neoplastic galls in the corn plant (Zea mays). Pathogenic mutants of U. maydis were produced by ultraviolet irradiation of cultures of nonpathogenic diploids homozygous at the b locus. The mutants formed smaller neoplasms, produced fewer teliospores, and showed higher frequencies of meiotic failure and lower rates of basidiospore survival than did the wild-type fungus.
本文探讨了真菌玉米黑粉菌（Ustilago maydis）在玉米植株（Zea mays）中诱导肿瘤性瘿瘤的能力的遗传基础。通过对在b位点纯合的非致病性二倍体培养物进行紫外线照射，产生了玉米黑粉菌的致病突变体。与野生型真菌相比，这些突变体形成的肿瘤较小，产生的冬孢子较少，减数分裂失败的频率较高，担孢子存活率较低。
