Flow charts are presented which systematise recently published work on gravitropic responses of the mushroom stipe of Coprinus cinereus. The hypothetical model represented by the charts suggests that the meiotic division is a pivotal point in the gravitational biology of the mushroom fruit body. The unilateral gravity vector seems to be required for formation of the tissues in which meiosis normally occurs, and stipes become gravitropically competent only after onset of meiosis. The gravitropism flow-chart also indicates that two signals emanate from the upper regions of the stipe, one promotes the process of gravitropic bending, and is followed by a second signal which compensates for excess bending and adjusts the stipe apex to the vertical. Formalisation of the various observations into flow-charts, even though comparatively simple at the moment, facilitates comparison with other species and concentrates attention on aspects requiring further experimental analysis.
文中呈现了流程图，这些流程图将最近发表的关于灰盖鬼伞菌柄重力反应的研究工作进行了系统化整理。这些图表所代表的假设模型表明，减数分裂是蘑菇子实体重力生物学中的一个关键点。单侧重力向量似乎是正常发生减数分裂的组织形成所必需的，并且菌柄只有在减数分裂开始后才具有重力感应能力。重力感应流程图还表明，菌柄上部区域发出两种信号，一种促进重力弯曲过程，随后是第二种信号，该信号补偿过度弯曲并将菌柄顶端调整到垂直方向。将各种观察结果整理成流程图，尽管目前相对简单，但有助于与其他物种进行比较，并将注意力集中在需要进一步实验分析的方面。
