Hibiscus bullseyes reveal mechanisms controlling petal pattern proportions that influence plant-pollinator interactions

This study identifies mechanisms controlling petal pattern proportions in Hibiscus trionum, showing how pre-patterned boundaries influence pollinator attraction through variations in bullseye size.

Geometry and cell wall mechanics guide early pollen tube growth in Arabidopsis thaliana

This study investigates how geometry and cell wall mechanics guide early pollen tube growth in Arabidopsis thaliana, showing that WT papilla cells direct growth while ktn1-5 mutants allow free movement along geodesics.

Invasion of the stigma by the pollen tube or an oomycete pathogen: striking similarities and differences

This study compares how stigma papillae respond to invasion by a pollen tube and an oomycete pathogen, revealing shared and distinct cellular responses.

Live-cell imaging of early events following pollen perception in self-incompatible Arabidopsis thaliana

The paper uses live-cell imaging in self-incompatible Arabidopsis to show that stigmatic cells control pollen hydration and respond to pollen tube intrusion by remodeling actin cytoskeleton.

Mechanical properties of the stigmatic cell wall mediate pollen tube path in Arabidopsis

The paper shows that mechanical properties of the papilla cell wall, influenced by KTN1, affect pollen tube path in Arabidopsis by altering cell wall stiffness and microtubule orientation.

The molecular signatures of compatible and incompatible pollination

The paper identifies molecular signatures of compatible and incompatible pollination in Arabidopsis thaliana by analyzing transcriptomic changes during pollen-stigma interaction.
