CEMA — Asparagus officinalis

Summary

A4U43_C05F35810, symbolised as CEMA (also known as DLDG1 or AoDLDG1) in asparagus (Asparagus officinalis) on chromosome 5, encodes a protein with ferrous iron transmembrane transporter, proton transporter, and potassium:proton antiporter activities. The product is localised to the chloroplast membrane, inner membrane, and envelope. This gene is associated with iron and potassium ion membrane transport, proton transmembrane transport, cell pH regulation, and nonphotochemical quenching. It is linked to chloroplast pH homeostasis, leaf greening, and light response. Related genes in other species are linked to non-photochemical quenching, abnormal chloroplast phenotypes, lithium content, and light intensity response traits.
