Grain proteome response to nitrogen and sulfur supply in einkorn (Triticum monococcum)

Wheat grain storage proteins (GSPs) make up most of the protein content of grain and determine flour end-use value. The synthesis and accumulation of GSPs depend highly on nitrogen (N) and sulfur (S) availability and it is important to understand the underlying control mechanisms. Here we studied how the einkorn (Triticum monococcum ssp. monococcum) grain proteome responds to different amounts of N and S supply during grain development. Two subproteomes were analyzed : albumin-globulin and nuclear proteins.
