FD1 — Solanum lycopersicum

Summary

SlFD1 (SOLYC10G075160.1) encodes a ferredoxin-type protein with 2Fe-2S cluster binding and phytochromobilin:ferredoxin oxidoreductase activity, localising to the chloroplast thylakoid. In tomato, SlFD1 is associated with photosynthetic electron transport in photosystem I, the xanthophyll cycle, chloroplast-nucleus signalling, and pigment and ferredoxin metabolism. It has been connected to agronomically important traits including leaf chlorophyll and nitrogen content, fruit length, weight and shape, harvest index, yield, net photosynthetic rate, quantum yield, bacterial blight disease resistance, water stress response, herbicide sensitivity, and chloroplast development. Studies of related genes in other species link the ferredoxin family to phytochromobilin biosynthesis, photosynthetic regulation, thermotolerance, defence responses, and antimicrobial activity.
