afila, the origin and nature of a major innovation in the history of pea breeding

Nadim Tayeh, Julie M. I. Hofer, Grégoire Aubert, Françoise Jacquin, Lynda Turner, Jonathan Kreplak, Pirita Paajanen, Christine Le Signor, Marion Dalmais, Stéphanie Pflieger, Valérie Geffroy, Noel Ellis, Judith Burstin

The paper identifies the molecular basis of the afila mutation in pea, showing it results from the deletion of two zinc finger transcription factors and reveals haplotype diversity at the af locus.
