摘要
Since the discovery of Systemin in tomatoes in 1991, many additional peptide hormones have been discovered in plants. Plant peptide hormones typically start as small precursor pro- teins （-100a.a.）, which include N-terminal secretory or anchor sequences, and are post-translationally processed into a smaller hormonally active peptide （on the range of 5-18 a.a.）. To date, peptide hormones have been shown to have diverse functions in plants, including nearly every aspect of develop- ment and morphogenesis. Here, we discuss recent reports regarding the CLV3/ESR-RELATED （CLE） and ROOT GROWTH FACTOR （RGF） families of peptide hormones.
