S locus glycoprotein (SLG) and S locus receptor kinase (SRK) cDNAs were isolated from an S allele present in a number of self-compatible Brassica napus lines. This A10 allele did not segregate with self-incompatibility in crosses involving other self-incompatible B. napus lines. The SLG-A10 cDNA was found to contain an intact open reading frame and was(More)
RNA metabolism during amphibian oogenesis has been investigated by the analysis of individual cDNA cloned sequences. Two cDNA clone libraries were constructed from the pA+ RNA of Xenopus ovary and of tadpole. The accumulation of RNAs complementary to individual clones was examined during oogenesis by isolating RNA from oocytes of different stages. There are(More)
In Brassica species, self-incompatibility has been mapped genetically to a single chromosomal location. In this region, there are two closely linked genes coding for the S locus glycoprotein (SLG) and S locus receptor kinase (SRK). They appear to comprise the pistil component of the self-incompatibility reaction. SLG and SRK are thought to recognize an(More)
An S-receptor kinase (SRK) gene associated with self-incompatibility in a Brassica napus subsp. oleifera line has been characterized. The SRK-A14 cDNA shows the highest levels of homology in the 5' end to the SLG-A14 cDNA present at the same locus. RNA blot analysis shows that the SRK-A14 gene is expressed predominantly in the pistil, and at lower levels in(More)
Although engraftment of undifferentiated pluripotent embryonic stem cells (ESCs) into the injured central nervous system (CNS) may lead to targeted cell replacement of lost/damaged cells, sustained proliferative activity combined with uncontrolled differentiation of implanted cells presents a risk of tumor formation. As tumorigenic potential is thought to(More)
