The pollen tube in a flowering plant grows in a direction that is influenced by the mechanical properties of the stigma papillae and the organization of structures called cortical microtubules inside these cells.
Convolutional neural networks and graph partitioning algorithms can be combined into an easy-to-use tool for segmentation of cells in dense plant tissue volumes imaged with light microscopy.
Development of a real-time SnRK2 kinase FRET reporter reveals rapid SnRK2 activation by ABA, but not by Methyl-Jasmonate or elevated CO2, while directly demonstrating basal SnRK2 activity in guard cells.

Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.
A gain-of-function in a new chemical defense resulted in no trade-offs and and independent evolution between novel and ancestral defenses, suggesting low redundancy among different defensive chemicals.

A fungal bioluminescence pathway can be reconstituted in planta to create luminescence in many plant species without external substrate addition, and be used to design customizable reporters of gene-expression.

Auxin binding to the ETTIN transcription factor disrupts the interaction between ETT and a TPL/TPR co-repressor and subsequently affects chromatin dynamics to ensure proper gynoecium development.
