AMP1 — Capsicum annuum

Summary

CaAMP1 (T459_24274) on pepper chromosome 9 encodes a metallocarboxypeptidase with carboxypeptidase activity, belonging to the peptidase M28 family. The gene is associated with meristem cell maintenance, regulation of meristem size, meristem maintenance, regulation of seed maturation, seed germination, proteolysis, signal transduction, defense response, virus-induced PTGS, and homeostasis. It has been linked to drought tolerance. The encoded protein localizes to the vacuole, endoplasmic reticulum, mitochondria, plasmalemma, and nucleus. Related genes in other species link the family to RNA silencing, plastochron, floral organ identity, leaf size, seed maturation, and root mass density, as well as phenotypes including super-bushy dwarf with increased leaf number and sterility, increased shoot branching and leaf number, and extremely small and sterile plants.
