Triticum monococcum L.
Einkorn wheat (Triticum monococcum) possesses high resistance to leaf, stem, and stripe rust due to pre-haustorial defense mechanisms and the presence of specific resistance genes (Sr21, Sr22, Sr35, Yr34).
In the reference 4 varieties crop Einkorn wheat, where this is mentioned in the description.
Einkorn is characterized by its interaction with Puccinia triticina, Puccinia graminis f. sp. tritici, and Puccinia striiformis f. sp. tritici. The key defense mechanism against leaf rust is pre-haustorial resistance, which suppresses pathogen development before haustoria form within plant tissues. Upon contact with the pathogens, resistant forms exhibit a hypersensitive response or show a complete absence of visible symptoms, except for faint chlorotic spots.
This species is a valuable source of resistance genes that are introgressed into polyploid wheat cultivars. Notable among these are genes Sr21, Sr22, and Sr35 for protection against stem rust, including the Ug99 (TTKSK) race, as well as gene Yr34 (Yr48) for the control of stripe rust. Resistance to leaf rust in this crop is often race-non-specific (horizontal) in nature, providing protection against a broad spectrum of pathotypes.
