P5CS — Triticum turgidum subsp. durum

Summary

TRITD1BV1G160830 (symbol P5CS, TtP5CS) on durum wheat chromosome 1B encodes a protein with glutamate 5-kinase (EC 2.7.2.11) and glutamylphosphate reductase (EC 1.2.1.41) activities, and is associated with proline metabolism, the response to desiccation, salt, hyperosmotic salinity, oxidative stress and abscisic acid, as well as root development, embryo development and the transition to flowering. In durum wheat, P5CS1 has been linked to drought tolerance. The gene is also associated with traits including salinity tolerance, photosynthetic rate, respiration rate, grain filling period, and with phenotypes such as proline accumulation, salt stress tolerance, freezing tolerance, pollen fertility, flowering time and root elongation under low water potential.
