Identification of Novel Broad-Spectrum Leaf Rust Resistance Sources from Khapli Wheat Landraces

Plants, 2022
Wheat leaf rust caused by Puccinia triticina Eriks is an important disease that causes yield losses of up to 40% in susceptible varieties. Tetraploid emmer wheat (T. turgidum ssp. Dicoccum), commonly called Khapli wheat in India, is known to have evolved

Evaluation of Wheat Germplasm for Resistance to Leaf Rust (Puccinia triticina) and Identification of the Sources of Lr Resistance Genes Using Molecular Markers

Plants, 2021
Leaf rust, caused by Puccinia triticina (Ptr), is a significant disease of spring wheat spread in Kazakhstan. The development of resistant cultivars importantly requires the effective use of leaf rust resistance genes.

Comparative genomics reveals lineage-associated structural variation and diversification in a barley fungal pathogen. [PDF]

New Phytol
Genome‐wide copy‐number variation landscape highlights structural divergence across Puccinia hordei isolates and potentially links Cyp51 amplification to fungicide insensitivity. Summary Leaf rust, caused by Puccinia hordei, is a major barley disease worldwide.

Wheat's war against stripe rust: Integrating host immunity, genomics and breeding for durable resistance. [PDF]

Plant Genome
Abstract Wheat (Triticum aestivum L.), a foundation of global food security, faces persistent threats from stripe rust caused by Puccinia striiformis f. sp. tritici (Pst). The pathogen thrives in cool and humid environments and regularly causes epidemics that lead to severe yield losses.
