New Peptide Discovery Redefines Plant Fertilization Signals in Arabidopsis | Newswise
Newswise — The peptide, named NON-DEFENSIN PEPTIDE ATTRACTANT 1 (NPA1), represents the first non-defensin-type attractant identified in dicots and expands the known diversity of fertilization cues in flowering plants. Unlike the commonly known cysteine-rich peptides (CRPs) such as LUREs, NPA1 operates independently of the typical defensin-like structure. Successful fertilization in flowering plants depends on precise…
