A change in the cell wall status initiates the elimination of the nucellus in Arabidopsis

Miryam Iannaccone, Weijie Xu, Dennys-Marcela Gómez-Páez, Sandrine Choinard, Elisa Maricchiolo, Alexis Peaucelle, Aline Voxeur, Kalina T. Haas, Catherine Lapierre, José M. Jiménez‐Gómez, Andrea Pompa, Enrico Magnani

The paper shows that pectin degradation in the cell wall initiates nucellus elimination in Arabidopsis, regulated by TRANSPARENT TESTA 16, and suggests this cell wall change drove seed evolution.

Too much sugar makes plants "pregnant": maternal sucrose signals fertilization in Arabidopsis seeds

Weijie Xu, Miryam Iannaccone, Dennys-Marcela Gómez-Páez, Sandrine Choinard, Jing Lü, Rozenn Le Hir, Sylvie Dinant, Lothar Kalmbach, Regina Feil, John Edward Lunn, Christian Meyer, Enrico Magnani

The paper shows that sucrose triggers a fertilization-independent response in Arabidopsis maternal tissues, initiating seed development through hormonal and sugar signaling.
