在子实体形成过程中，橙黄点霉产生一种胞外的、可扩散的信号分子（信息素）。在光照和黑暗条件下，信息素都能缩短聚集期，并代替光照刺激聚集体成熟为子实体。细胞在光照下比在黑暗中对较低浓度的信息素更敏感，这可能解释了光对聚集和子实体形成的刺激。信息素还与GMP协同作用，缩短了聚集期。信息素的化学行为是一种低分子量的脂质。
An extracellular, diffusible signaling molecule (pheromone) was produced by Stigmatella aurantiaca during fruiting body formation. The pheromone decreased the aggregation period in both the light and the dark and substituted for light in stimulating the maturation of aggregates into fruiting bodies. The cells were more sensitive to lower concentrations of pheromone in the light than in the dark, possibly explaining the stimulation of aggregation and fruiting body formation by light. The pheromone also interacted cooperatively with GMP to shorten the aggregation period. The pheromone behaved chemically as a low-molecular-weight lipid.
