Abstract excerpt

In flowering plants, successful male reproduction requires the sophisticated interaction between somatic anther wall layers and reproductive cells. Timely degradation of the innermost tissue of the anther wall layer, the tapetal layer, is critical for pollen development. Ca2+ is a well-known stimulus for plant development, but whether it plays a role in affecting male reproduction remains elusive. Here we report...
