Wheat grain hardness results from highly conserved mutations in the friabilin components puroindoline a and b.

Abstract

"Soft" and "hard" are the two main market classes of wheat (Triticum aestivum L.) and are distinguished by expression of the Hardness gene. Friabilin, a marker protein for grain softness (Ha), consists of two proteins, puroindoline a and b (pinA and pinB, respectively). We previously demonstrated that a glycine to serine mutation in pinB is linked… (More)
