to enhance germplasms of bread wheat, a gene, encoding the smallest y-type high molecular weight glutenin subunit (hmw gs) gene (12.4t) from the d-genome using synthetic hexaploid approach was introgressed into bread wheat. tetraploid wheat (t. turgidum cv. langdon) was crossed with t. tauschii accession aus24092. immature embryos were rescued and placed onto b5 regeneration media. hybrid f1 pl...

Although it is understood that the composition of riparian trees can affect stream function through leaf litter fall, the potential effects of genetic variation within species are less understood. Using a naturally hybridizing cottonwood system, we examined the hypothesis that genetic differences among two parental species (Populus fremontii and P. angustifolia) and two groups of their hybrids ...

Microarray analysis of gene expression patterns in immature ear, seedling and embryo tissues from the maize inbred lines B73 and Mo17 identified numerous genes with variable expression. Some genes had detectable expression in only one of the two inbreds; most of these genes were detected in the genomic DNA of both inbreds, indicating that the expression differences are likely caused by differen...

Rapid and extensive genetic introgression has occurred between Pecos pupfish (Cyprinodon pecosensis) and sheepshead minnow (Cyprinodon variegatus) in the wild. We studied both female mate choice and male-male competition for mates among C. pecosensis, C. variegatus, and their F1 hybrids to determine what role these behaviours played in the formation of the hybrid swarm. Female C. pecosensis pre...

Three murine monoclonal anti-ssDNA autoantibodies have been produced by fusion of spleen cells from NZB/NZW F1 hybrid mice with Sp2/0-Ag 14 murine myeloma cells. Specificity studies characterizing monoclonal anti - ssDNA autoantibodies revealed binding patterns for nucleotides. Clone E-4-1 showed preferential binding with mono-di-and polyguanosine. Clones E-4-4 and E-11-1 specitically bound mon...

Abstract Shared ancestral variation and introgression complicates the reconstruction of phylogenetic relationships among closely related taxa. Here we use overall genomic compatibility as an alternative estimate of species relationships in a group where divergence is rapid and genetic exchange is common. Heliconius heurippa, a butterfly species endemic to Colombia, has a colour pattern genetica...
