Disentangling blade and vasculature shape in grapevine leaves

Wahiba Yahiaoui, Safa Smail, Yemeen Ayub, Qiao Lu, Peter S. Cousins, Luis Antonio Diaz-Garcia, Margaret H. Frank, Lauren R. Headland, Ciera C Martinez, Zoë Migicovsky, Aashish Ranjan, Neelima Sinha, Joel F. Swift, Efrain Torres‐Lomas, Elizabeth Munch, , Daniel H. Chitwood

This study uses topological data analysis and deep learning to show that grapevine leaf blade and vasculature shapes are predictively linked, suggesting a one-to-one relationship between the two tissues.
