FPS1 — Phaseolus vulgaris

Summary

PHAVU_006G136300, designated PvFPS1, encodes a protein with geranyltranstransferase and dimethylallyltransferase activities that binds metal ions. This French bean gene on chromosome 6 is associated with the biosynthesis of farnesyl diphosphate, geranyl diphosphate, carotenoids, triterpenoids, saponins, and cholesterol. PvFPS1 has been linked to responses to salicylate, jasmonic acid, gibberellin, and fungal molecules, as well as to protein transport. The encoded protein localises to plastids, cytosol, cytoplasm, and nucleus. Associations with plant growth, seed germination, embryo and seedling development, terpenoid biosynthesis, sitosterol content, and aphid resistance have been observed. Studies of related genes in other species connect the family to seed development, chloroplast development, isoprenoid biosynthesis, seed germination capacity, aphid repellence, and jasmonic acid response.
