AMP1 — Capsicum annuum

Summary

CaAMP1 (T459_18645) on pepper chromosome 7 encodes a peptidase M28 domain-containing protein with carboxypeptidase and metallocarboxypeptidase activity. 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 post-transcriptional gene silencing, and homeostasis. Its product localizes to the vacuole, endoplasmic reticulum, mitochondria, plasmalemma, and nucleus. CaAMP1 has also been connected to drought tolerance. Related genes in other species link the family to RNA silencing, plastochron, floral organ identity, leaf size, seed maturation, and shoot branching phenotypes.
