FNR — Zea mays

Summary

ZM00001EB299960, designated ZmFNR, encodes a ferredoxin-NADP reductase (EC 1.18.1.2) with FAD- and NAD-binding domains, localised to the chloroplast thylakoid membrane and stroma. The gene is associated with C4 photosynthesis, light absorption, dark adaptation, oxidative phosphorylation, water transport, and response to water. It is linked to hydrogen metabolism, quinone anabolism, the GABA shunt, steroid metabolism, sucrose breakdown, and the oxidative pentose pathway. Associations with traits include quantum yield, transpiration rate, stomatal resistance, respiration rate, heterosis, heat tolerance, root length, and root growth, as well as nitrite detoxification. Studies of related genes in other species link the family to root thickness, seed dormancy, and photochemical quenching.
