AMP1 — Capsicum annuum

Summary

CaAMP1 (T459_15527) on pepper chromosome 5 encodes a metallocarboxypeptidase with carboxypeptidase activity, belonging to the peptidase M28 family and containing a TFR-like dimerisation domain. It is associated with meristem cell maintenance, regulation of meristem size, and meristem maintenance, as well as regulation of seed maturation, seed germination, and developmental processes. The gene is linked to proteolysis, signal transduction, defense response, virus-induced post-transcriptional gene silencing, and homeostasis. It has been connected to drought tolerance. The encoded protein localises to the vacuole, endoplasmic reticulum, mitochondria, plasmalemma, and nucleus. Studies of related genes in other species link the family to plastochron, floral organ identity, leaf size, seed maturation, and root mass density, as well as phenotypes including super-bushy dwarfism, increased shoot branching, and altered ABA response.
