SPX3 (TRAESCS2B02G195900) — triticum aestivum

Summary

TRAESCS2B02G195900, designated TaSPX3 on chromosome 2B of bread wheat, encodes an SPX domain-containing protein. The gene is associated with the positive regulation of cellular response to phosphate starvation and with cellular response to cold. TaSPX3 has been linked to shoot phosphorus content, phosphate homeostasis, and the phosphate starvation response. Associations also include flag leaf angle, plant height, heading time, anthesis time, grain weight, grain yield, and wheat stripe rust disease response. The encoded protein localises to both the cytoplasm and nucleus. TaSPX3 is associated with the downregulation of unidimensional cell growth and regulation of leaf development. Related genes in other species are linked to phosphorus starvation tolerance and flowering time.
