Thylakoid membrane transporter SecE1 is required for chloroplast development and photosynthetic function in Arabidopsis.
Chloroplast biogenesis depends on protein transport, pigment biosynthesis, and thylakoid membrane assembly, which are coordinated through anterograde (nucleus-to-plastid) and retrograde (plastid-to-nucleus) signaling. The chloroplast Sec translocon mediates the import of nuclear-encoded precursor proteins across the th...
