Ontogenesis of Trichothecium roseum during biosynthesis of trichothecin was studied during submerged cultivation on maize and synthetic media. Growth of the fungus is polycyclic; several generations of the submerged mycelium develop from the submerged conidia on the maize medium, and from the submerged conidia, chlamydospores and budding mycelium on the synthetic medium. Differentiation of the mycelium favours biosynthesis of the antibiotic. The nuclei in the cells of the submerged mycelium differ by their number, dimensions, and shape (round and elongated, polyploid). Several nuclei are found in the cells of the submerged mycelium more often during growth on the synthetic medium; this phenomenon is related to the reproductive cells -- submerged conidia and chlamydospores.
在玉米和合成培养基上进行深层培养时，研究了粉红单端孢霉在合成单端孢霉毒素过程中的个体发育。真菌的生长是多循环的；在玉米培养基上，几代深层菌丝体由深层分生孢子发育而来，在合成培养基上则由深层分生孢子、厚垣孢子和出芽菌丝体发育而来。菌丝体的分化有利于抗生素的生物合成。深层菌丝体细胞中的细胞核在数量、大小和形状（圆形、细长形、多倍体）上存在差异。在合成培养基上生长期间，深层菌丝体细胞中更常发现有几个细胞核；这种现象与生殖细胞——深层分生孢子和厚垣孢子有关。
