Late blight, caused by the oomycete pathogen Phytophthora infestans, is the most devastating potato disease in the world. Control of late blight in the United States and other developed countries relies extensively on fungicide application. We previously demonstrated that the wild diploid potato species Solanum bulbocastanum is highly resistant to all known(More)
Somatic hybrids have been obtained between potato and Solanum bulbocastanum PI 245310, a Mexican diploid (2n=2x=24) species. Through restriction fragment length polymorphism (RFLP) and randomly amplified polymorphic DNA (RAPD) analyses it was found that the somatic hybrids contain each chromosome of the diploid parent and that the synteny of RFLP markers(More)
In this report we discuss the impact of polarized foregrounds on a future CMBPol satellite mission. We review our current knowledge of Galactic polarized emission at microwave frequencies, including synchrotron and thermal dust emission. We use existing data and our understanding of the physical behavior of the sources of foreground emission to generate sky(More)
Development of efficient methods to transfer large DNA fragments into plants will greatly facilitate the map-based cloning of genes. The recently developed BIBAC and TAC vectors have shown potential to deliver large DNA fragments into plants via Agrobacterium-mediated transformation. Here we report that BIBAC and TAC clones containing potato genomic DNA(More)
The wild potato species Solanum bulbocastanum is a source of genes for potent late blight resistance. We previously mapped resistance to a single region of the S. bulbocastanum chromosome 8 and named the region RB (for "Resistance from S. Bulbocastanum"). We now report physical mapping and contig construction for the RB region via a novel reiterative method(More)
