Characterization of wheat-alien translocations conferring resistance to diseases and pests: current status

Wild relatives of common wheat, Triticum aestivum, and related species are an important source of disease and pest resistance and several useful traits have been transferred from these species to wheat. C-banding and in situ hybridization analyses are powerful cytological techniques allowing the detection of alien chromatin in wheat. Cbanding permits identification of the wheat and alien chromosomes involved in wheat-alien translocations, whereas genomic in situ hybridization analysis allows determination of their size and breakpoint positions. The present review summarizes the available data on wheat-alien transfers conferring resistance to diseases and pests. Ten of the 57 spontaneous and induced wheat-alien translocations were identified as whole arm translocations with the breakpoints within the centromeric regions. The majority of transfers (45) were identified as terminal translocations with distal alien segments translocated to wheat chromosome arms. Only two intercalary wheat-alien transloctions were identified, one induced by radiation treatment with a small segment of rye chromosome 6RL (H25) inserted into the long arm of wheat chromosome 4A, and the other probably induced by homoeologous recombination with a segment derived from the long arm of a group 7 Agropyron elongatum chromosome with Lrl9 inserted into the long arm of 7D. The presented information should be useful for further directed chromosome engineering aimed at producing superior germplasm.

“…A resistance gene (Wsm1) was identified and transferred from intermediate wheat-grass [Thinopyrum intermedium (Host) Barkworth & DR Dewey] to wheat to limit infection by the virus and WCM colonization (Friebe et al, 1996). Transfer of this resistance traces to crosses between wheat and intermediate wheat-grass produced more than three decades ago (Wells et al, 1973(Wells et al, , 1982. Subsequent breeding led to the development of wheat lines with Wsm1 and the potential to prevent major economic losses.…”

Wheat streak mosaic virus (WSMV) is one of the most important diseases limiting winter wheat (Triticum aestivum L.) production in the western Great Plains of North America. There is no known effective WSMV resistance within the primary gene pool of wheat. However, a resistance gene (Wsm1) has been transferred to wheat from a perennial relative, intermediate wheat-grass [Thinopyrum intermedium (Host) . Nebraska-adapted winter wheat lines carrying Wsm1 were used to characterize the effects of this alien introgression on agronomic and quality traits. Sister-lines from six breeding populations were evaluated under virus-free conditions, and under a naturally occurring viral infection. In uninfected locations, no significant difference for grain yield was detected between resistant (R) and susceptible (S) lines, when averaged over populations, but resistant lines had significantly higher test weights. Within populations, significantly higher grain yield was observed only in population 1, while significantly higher test weights occurred in populations 1, 2, 5 and 6. At the infected location, resistant lines were significantly higher in yield in five of six populations. In two of six populations, susceptible lines were significantly higher in bread loaf volume and bake mix time, while in the remaining populations, no significant quality differences were observed. As the Wsm1 gene provided yield advantages under viral infection, and there was no yield detriment in the absence of the virus, its deployment in hard winter wheat cultivars merits consideration.

“…However, among the Triticeae, the perennial genera, Secale cereale, Agropyron elongatum, Agropyron intermedium and other Agropyron species have been found resistant to either the virus, vector or both (McKinney & Sando, 1951;Somsen & Still, 1970;Martin et al, 1976;Sharma et al, 1984;Stoddard et al, 1987aStoddard et al, , 1987b. Genes for resistance to WSMV have been transferred from Agropyron intermedium (Lay et al, 1971;Wells et al, 1973Wells et al, , 1982Wang et al, 1977;Liang et al, 1979) and Agropyron elongatum (Sebesta & Bellingham, 1963;Larson & Atkinson, 1970;Sebesta et al, 1972) to wheat. Two genes Cmc1 (Thomas & Conner, 1986;Thomas and Whelan, 1991) and Cmc2 (Larson & Atkinson, 1970) conferring resistance to wheat curl mite colonization have been identified and transferred to wheat.…”
