Genetics of Resistance to Leaf Rust in Wheat: An Overview in a Genome-Wide Level
Due to the global warming and dynamic changes in pathogenic virulence, leaf rust caused by Puccinia triticina has greatly expanded its epidermic region and become a severe threat to global wheat production. Genetic bases of wheat resistance to leaf rust mainly rely on the leaf rust resistance (Lr) gene or quantitative trait locus (QLr). Although these genetic loci have been insensitively studied during the last two decades, an updated overview of Lr/QLr in a genome-wide level is urgently needed. This review summarized recent progresses of genetic studies of wheat resistance to leaf rust. Wheat germplasms with great potentials for genetic improvement in resistance to leaf rust were highlighted. Key information about the genetic loci carrying Lr/QLr was summarized. A genome-wide chromosome distribution map for all of the Lr/QLr was generated based on the released wheat reference genome. In conclusion, this review has provided valuable sources for both wheat breeders and researchers to understand the genetics of resistance to leaf rust in wheat.
