Gene Symbol detail

Gene Symbold
Class Level 1 Reaction to Puccinia triticina
Level 2 Genes for resistance
Level 3
Level 4
Symbol Wild Type Lr34
Synonyms LrT2{321}
Symbol comment In addition to conferring seedling and adult plant resistance, Lr34 responds in a complementary manner when combined with either Lr33 or LrT3 {321}. In the Thatcher background, Lr34 is associated with increased resistance to stem rust {299,321}.
Although the resistance gene in the near-isogenic Thatcher line, RL6077, was considered to be Lr34 on the basis of disease response, leaf tip necrosis and its association with resistance to stripe rust, a cross with RL6058 segregated for two genes. A translocation to another chromosome was suggested {324}.

Comment A QTL, which is likely to correspond to Lr34, was identified in the Opata 85/W-7984 (ITMI) RI mapping population. The resistance was contributed by Opata 85 {0090}.
On the basis of leaf tip necrosis and lack of segregation in a diallel, cv. Saar, Simogh, Homa, Parastoo and Cocnoos were considered to have Lr34, but each also possessed 2 or 3 additional adult plant resistance factors {10110}.
This gene is identical to Yr18, Pm38 and Ltn and confers stem rust resistance in some genetic backgrounds.
Diagnostic markers based on the gene sequence are reported in {10713}; AC Domain, Cappelle Desprez, H-45, Jagger, Newton, RL 6077, and H-45 do not carry Lr34 {10713}.
