Mismatch between pollen and pistil size causes asymmetric mechanical reproductive isolation across Phlox species
A. F. Feller, G. Burgin, N. Lewis, R. Prabhu, R. Hopkins
The paper investigates how differences in style length between Phlox species create an asymmetric mechanical barrier to reproduction, reducing heterospecific seed set and revealing a link between pollen size and pollen tube growth.
