FPS (TRAESCS2B02G530100) — triticum aestivum

Summary

TRAESCS2B02G530100 (symbol FPS, also known as Tafps1 and Tafps2) on bread wheat chromosome 2B encodes a farnesyl pyrophosphate synthase, a prenyltransferase with geranyltranstransferase and dimethylallyltransferase activities that binds metal ions. The gene is associated with the biosynthesis of isoprenoids, including carotenoids, geranyl diphosphate, farnesyl diphosphate, triterpenoids, saponins, and cholesterol, as well as with responses to jasmonic acid, salicylic acid, gibberellin, fungal molecules, and yeast. It has been connected to aphid resistance, seed dormancy, seed germination, grain yield, drought tolerance, stripe rust, and photosynthetic traits such as net photosynthetic rate, quantum yield, transpiration rate, and photochemical quenching. The encoded protein localises to the cytoplasm and nucleus. Studies of related genes in other species place the family in prenyltransferase pathways (EC 2.5.1.1 and 2.5.1.10).
