Plants orientate their growth either towards (in roots) or away from (in shoots) the Earth's gravitational field. While we are now starting to understand the molecular architecture of these gravity response pathways, the gravity receptor remains elusive. This perspective looks at the biology of statoliths and suggests it is conceivable that their immediate environment may be tuned to modulate the strength of the gravity response. It then suggests how mutant screens could use this hypothesis to identify the gravity receptor.
植物会使其生长方向朝向（根部）或背离（茎部）地球引力场。虽然我们现在开始了解这些重力响应途径的分子结构，但重力感受器仍然难以捉摸。这篇综述探讨了平衡石的生物学特性，并提出其直接环境有可能被调节以调控重力响应的强度，进而提出突变体筛选如何利用这一假说来鉴定重力感受器。
