紫外光照射下的未分裂的龙形体,使这些龙形体形成一个或多个缺失的子代菌落的高百分比。产生的菌落在形态上是正常的,在下一代产生完全正常的菌落。这些结果表明,成熟无性群体中生殖腺的分布反映了一种紫外线不稳定的形态发生物质在未分裂生殖腺中的分布。
Ultraviolet irradiation of undivided gonidia ofVolvox cartericauses these gonidia to form a high percentage of daughter colonies with one or more missing gonidia. The colonies produced are otherwise normal in morphology and produce completely normal colonies in the next generation. These results are interpreted to mean that the distribution of gonidia in mature asexual colonies reflects the distribution in the undivided gonidium of a UV-labile morphogenetic substance.
