Molecular cytogenetic characterisation of a leaf-rust resistant wheat-Thinopyrum ponticum partial amphiploid

Molecular cytogenetic characterization of parental genomes in the partial amphidiploid Triticum aestivum × Thinopyrum ponticum

The wheat line PF 839197 and six hybrid derivatives from a cross between PF 839197 and Thinopyrum ponticum were cytologically characterized by fluorescent in situ hybridization (FISH). Probes for the 5S and 45S rDNA genes (pTa794 and pTa71, respectively), a highly repetitive rye sequence (pSc119.2), the synthetic oligonucleotide (AAG)5, and total genomic DNA from Th. ponticum and rye were used....

Baryonic Z ′ connection of LEP R b , c data with Tevatron ( W , Z , γ ) bb̄ events

The mixing of a new Z ′ boson with the Z significantly improves the fit to the LEP precision electroweak data, provided that the Z ′ couples mainly to quarks. If M Z 2 < 200 GeV, the s-channel Z 2 production and (W, Z, γ)Z 2 pair production cross sections at the Tevatron give an excess above QCD of b ¯ b and (W, Z, γ)b ¯ b events, respectively, with invariant mass m(b ¯ b) ≈ M Z 2 , which provi...

Simultaneous visualization of different genomes (J, JSt and St) in a Thinopyrum intermedium × Thinopyrum ponticum synthetic hybrid (Poaceae) and in its parental species by multicolour genomic in situ hybridization (mcGISH)

Multicolour genomic in situ hybridization (mcGISH) using total genomic DNA probes from Thinopyrum bessarabicum (Săvulescu & Rayss, 1923) Á. Löve, 1984 (genome J(b) or E(b), 2n = 14), and Pseudoroegneria spicata (Pursh, 1814) Á. Löve, 1980 (genome St, 2n = 14) was used to characterize the mitotic metaphase chromosomes of a synthetic hybrid of Thinopyrum intermedium (Host, 1805) Barkworth & D.R. ...

RAPD and ISSR-assisted identification and development of three new SCAR markers specific for the Thinopyrum elongatum E (Poaceae) genome.

Diploid Thinopyrum elongatum, a wild relative of wheat, contains many agronomically desirable traits and has potential for increasing genetic variability and introducing desirable characters in this crop. Few molecular markers are available for rapid screening of T. elongatum genome segments in the wheat genetic background. We used 36 RAPD primers and 33 ISSR primers to screen for polymorp...
