CEO — Triticum aestivum

Summary

TRAESCS1A02G195400 (TaCEO) on wheat chromosome 1A encodes a protein with NAD ADP-ribosyltransferase activity, a sodium:hydrogen exchanger, and transcriptional co-regulator functions, containing WWE_RCD1, RST, and poly(ADP-ribose) polymerase catalytic domains. The gene is associated with salinity stress tolerance in wheat, pre-harvest sprouting, and regulation of auxin biosynthesis, photosynthesis, and shade avoidance. It is linked to cellular responses to zinc and oxidative stress, chlorophyll breakdown, immune response downregulation, and microtubule assembly. Associations include shoot system boron content, sodium and potassium uptake, boron and zinc sensitivity, vegetative vigor, starch grain synthesis, carotenoid content, iron concentration, panicle length, seed dormancy, and leaf senescence. Related genes in other species are associated with salt tolerance, ion homeostasis, drought and heat stress tolerance, light acclimation, and phototropism.
