The damage to wheat crops by stem rust poses a threat the food security of world’s population. species Thinopyrum ponticum (Podpěra, 1902) (Z.-W. Liu and R.-C. Wang, 1993) is non-host for fungus Puccinia graminis f. sp. tritici Eriks. Henn. (Pgt). Sr24, Sr25, Sr26 genes, transferred from Th. gene pool, protect cultivars disease in different regions world. study resistance (NHR) effects introgre...

Enrichment of grains with anthocyanins is considered a feasible approach to improving the nutritional properties bread wheat. Here, two black-grained substitution lines either 4B or 4D chromosomes substituted by wheatgrass (Thinopyrum ponticum) 4Th were created via marker-assisted combining anthocyanin biosynthesis regulatory genes Pp-1, Pp3 (Purple pericarp), and Ba1 (Blue aleurone) in genetic...

Lophopyrum elongatum, a close relative of wheat, provides a source of novel genes for wheat improvement. Molecular markers were developed to monitor the introgression of L. elongatum chromosome segments into hexaploid wheat. Existing simple sequence repeats (SSRs) derived from genomic libraries were initially screened for detecting L. elongatum loci in wheat, but only 6 of the 163 markers teste...

Abstract Background Thinopyrum intermedium (2n = 6x 42) is an important wild perennial Triticeae species exhibiting many potentially favorable traits for wheat improvement. Wheat- Th . partial amphiploids serve as a bridge to transfer desirable genes from into common wheat. Results Three octoploid Trititrigia accessions (TE261–1, TE266–1, and TE346–1) with good resistances stripe rust, powdery ...

A large percentage of the repetitive elements in mammalian genomes are retroelements, which have been moved primarily by LINE-1 retrotransposons and endogenous retroviruses. Although LINE-1 elements have remained active throughout the mammalian radiation, specific groups of endogenous retroviruses generally remain active for comparatively shorter periods of time. Identification of an unusual ex...

Human rhinoviruses (HRVs) are the main cause of cold-like illnesses, and currently no vaccine or antiviral therapies against HRVs are available to prevent or mitigate HRV infection. There are more than 150 antigenically heterogeneous HRV serotypes, with ∼90 HRVs belonging to major group species A and B. Development of small animal models that are susceptible to infection with major group HRVs w...
