Asexual development, conidiation, in the filamentous fungus Neurospora crassa is a simple developmental process that starts with the growth of aerial hyphae. Then, the formation of constrictions and subsequent maturation gives rise to the mature conidia that are easily dispersed by air currents. Conidiation is regulated by environmental factors such as light, aeration and nutrient limitation, and by the circadian clock. Different regulatory proteins acting at different stages of conidiation have been described. The role of transcription factors such as FL, and components of signal transduction pathways such as the cAMP phosphodiesterase ACON-2 suggest a complex interplay between differential transcription and signal transduction pathways. Comparisons between the molecular basis of conidiation in N. crassa and other filamentous fungi will help to identify common regulatory elements.

景天孢子的分生孢子：模型真菌的营养繁殖。

在丝状真菌Neurospora crassa中的无性繁殖，绝育是一个简单的发育过程，始于气生菌丝的生长。然后，颈缩的形成和随后的成熟产生了易于通过气流分散的成熟分生孢子。分娩受环境因素（例如光照，通风和养分限制）以及昼夜节律的影响。已经描述了在分生过程的不同阶段起作用的不同调节蛋白。转录因子（例如FL）的作用以及信号转导途径（例如cAMP磷酸二酯酶ACON-2）的成分表明差异转录和信号转导途径之间存在复杂的相互作用。准con割分子基础的比较猪笼草和其他丝状真菌将有助于鉴定常见的调控元件。
