AMP1 — Capsicum annuum

Summary

CaAMP1 (T459_21094) on pepper chromosome 7 encodes an aminopeptidase NAALADL1 with metallocarboxypeptidase, aminopeptidase, and metallopeptidase activities, belonging to the peptidase M28 family. The gene is associated with meristem cell maintenance, regulation of meristem size, seed germination, regulation of seed maturation, proteolysis, defense response, signal transduction, virus-induced PTGS, and homeostasis. It is linked to drought tolerance. The encoded protein localizes to the apical plasma membrane, vacuole, endoplasmic reticulum, mitochondria, plasmalemma, and nucleus. Related genes in other species are linked to 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, and increased shoot branching.
