Two 24-mer SCAR primers (SW13) were developed from a previously identified 10-mer RAPD primer (OW13(690)) linked to the I gene, which conditions resistance to bean common mosaic virus (BCMV) in common bean. Linkage between SW13 and the I gene was tested in three F2 populations segregating for both SW13 and the I gene: N84004/Michelite (1.0 +/- 0.7 cM),(More)
Previous studies involving platelet-derived growth factor (PDGF) have been based on the premise that a single cell-surface receptor binds all three isoforms of PDGF (AA, BB, and AB). It is now shown that two populations of PDGF receptor exist and can be distinguished by their ligand binding specificity. The B receptor binds only the BB dimer, whereas the(More)
Murine homologs of the PDGF A, PDGF B, and PDGF receptor alpha subunit genes were cloned. These were used, together with a mouse PDGF receptor beta subunit cDNA clone, to monitor gene expression in early postimplantation mouse embryos and in F9 embryonal carcinoma cells. RNAse protection analysis shows that PDGF A chain, but not B chain, mRNA is expressed(More)
DNA-damaging agents produce a plethora of cellular responses that include p53 induction, cell cycle arrest, and apoptosis. It is generally assumed that it is the DNA damage produced by these agents that triggers such responses, but there is limited direct evidence to support this assumption. Here, we used DNA alkylation repair proficient and deficient(More)
It is well-known that production scheduling can be largely categorized into open and closed-shops (Graves (1981)). Open-shops are job-shops, flow-shops, machine-shops and project-shops and deal exclusively with the assignment, sequencing and timing decisions (Pinedo (1995)). Closed-shops on the other hand also deal with the same three decision-groups as(More)
We have characterized platelet-derived growth factor (PDGF) C, a novel growth factor belonging to the PDGF family. PDGF-C is a multidomain protein with the N-terminal region homologous to the extracellular CUB domain of neuropilin-1, and the C-terminal region consists of a growth factor domain (GFD) with homology to vascular endothelial growth factor (25%)(More)
High affinity binding of platelet-derived growth factor (PDGF) has been proposed to involve the interaction of the dimeric PDGF ligand with two receptor subunits, designated alpha and beta. We have cloned and expressed a human PDGF receptor cDNA which differs in sequence from the beta-subunit and which has the PDGF binding properties and monoclonal antibody(More)
We have determined the organization and transcription of a Drosophila DNA segment coding for the purine pathway enzyme, GAR transformylase. Because the transcript encoding this enzyme is very rare, we used a novel method for exon mapping without isolating a cDNA. Our results suggest a long polypeptide having multiple domains, with GAR transformylase at the(More)
Platelet-derived growth factor (PDGF) receptor transfectants of a fibroblastoid cell line (BHK) have been used to investigate the ability of the three dimeric forms of PDGF to elicit a chemotactic response. Cells transfected with the beta receptor subunit were only responsive to PDGF-BB, whereas cells expressing the alpha-receptor subunit were equally(More)
The putative role of tissue factor (TF) as a receptor involved in signal transduction is indicated by its sequence homology to cytokine receptors (Bazan, J. F. (1990) Proc. Natl. Acad. Sci. U. S. A. 87, 6934-6938). Signal transduction induced by binding of FVIIa to cells expressing TF was studied with baby hamster kidney (BHK) cells stably transfected with(More)
