Abstract excerpt

The number of seeds a plant produces depends on the number of ovules initiated within the carpels by meristematic tissue called the placenta. Previous studies indicated that ERECTA-LIKE1 (ERL1) and ERL2 receptors and their extracellular ligand EPIDERMAL PATTERNING FACTOR-LIKE2 (EPFL2) promote ovule initiation. Here, we expand this regulatory network by demonstrating that in Arabidopsis (Arabidopsis thaliana),...
