In conclusion, although surgery remains the first choice to treat ROLC, a considerable number of patients are inoperable. EBRT is an alternative, but is hampered since the ROLC is effectively invisible. We report that the use of metallic clips placed during bronchoscopy can make ROLC visible for the radiation oncologist. The clips appear to be safe, well tolerated and removable in inoperable pa...

In cell cultures of carrot (Daucus carota l.), somatic embryogenesis can be induced by transferring cells from a medium containing 2,4-dichlorophenoxyacetic acid (2,4-D) to one devoid of 2,4-D. Previous analysis of transgenic carrot cells containing the 5' noncoding sequence of the Ri plasmid rolC and a structural gene for bacterial 0-glucuronidase (uidA) has shown that the chimeric gene is act...

In cell cultures of carrot (Daucus carota L.), somatic embryogenesis can be induced by transferring cells from a medium containing 2,4-dichlorophenoxyacetic acid (2,4-D) to one devoid of 2,4-D. Previous analysis of transgenic carrot cells containing the 5' non-coding sequence of the Ri plasmid rolC and a structural gene for bacterial beta-glucuronidase (uidA) has shown that the chimeric gene is...

We describe a genetic switch based on the Ac transposable element of maize and the rolC gene of Agrobacterium rhizogenes, a dominant gene, which has pleiotropic effects on plant growth and morphology. Moreover, rolC gene expression under the control of the 35S cauliflower mosaic virus promoter decreases chlorophyll content in transgenic tobacco plants. Chlorophyll is a visible cell-autonomous m...

Wild-type potato (Solanum tuberosum L.) plants and their transformants harboring agrobacterial rolB or rolC genes under control of the patatin class I promoter were cultured in vitro. These plants were used as a source of single-node stem cuttings. The structure of native starch in tubers formed on cuttings was determined using methods of X-ray scattering and differential scanning microcalorime...

BACKGROUND The ability of conventional CT scans and fiberoptic bronchoscopy to localize and properly stage radiographically occult lung cancer (ROLC) in the major airways is limited. High-resolution CT (HRCT) scanning and autofluorescence bronchoscopy (AFB) may improve the assessment of ROLC before the most appropriate therapy can be considered. PATIENTS AND METHODS We prospectively studied 2...

This paper presents the map and DNA sequence analysis of pRi8196 transferred DNA (T-DNA) genes encoding root-inducing and mannopine synthesis functions. A canonical 24-base-pair border repeat as well as two "pseudoborders" are present at the functional right T-DNA border. To the left of this border are homologs of the mas1' and mas2' genes of TR pRiA4. Next to these are five open reading frames...

The extent of phenotypic variation of St. John's wort (Hypericum perforatum L.) plants transformed with wild agropine ATCC 15834 Agrobacterium rhizogenes plasmid was evaluated with respect to the number of rol genes integrations. The transfer of T(L)-DNA to plant explants during each transformation event was incomplete with different rolA, rolB, and rolC copy numbers. Along with typical feature...
