Plant-derived transfer DNAs.
The transfer of DNA from Agrobacterium to plant cell nuclei is initiated by a cleavage reaction within the 25-bp right border of Ti plasmids. In an effort to develop all-native DNA transformation vectors, 50 putative right border alternatives were identified in both plant expressed sequence tags and genomic DNA. Efficacy tests in a tobacco (Nicotiana tabacum) model system demonstrated that 14 o...
متن کاملHorizontal Gene Transfer Contributes to Plant Evolution: The Case of Agrobacterium T-DNAs
Horizontal gene transfer (HGT) can be defined as the acquisition of genetic material from another organism without being its offspring. HGT is common in the microbial world including archaea and bacteria, where HGT mechanisms are widely understood and recognized as an important force in evolution. In eukaryotes, HGT now appears to occur more frequently than originally thought. Many studies are ...
متن کاملCoexistence of Bos taurus and B. indicus mitochondrial DNAs in nuclear transfer-derived somatic cattle clones.
We investigated the mitochondrial DNA (mtDNA) composition in one of the largest adult somatic mammalian clones (n = 20) reported so far. The healthy cloned cattle were derived from nuclear transfer of an identical nuclear genetic background (mural granulosa donor cells including surrounding cytoplasm) into enucleated oocytes with either Bos indicus or B. taurus mtDNA. Here we report the first c...
متن کاملSupercoiled mitochondrial DNAs from plant tissue culture cells.
Supercoiled mitochondrial DNA (mtDNA) has been isolated in preparative amounts from five different plant species and compared on agarose gels. The gels reveal considerable mtDNA size heterogeneity within each species as well as substantial differences in the range and frequency of the mtDNA size classes among the different plants. The two lowest size classes of three of the plants have been ext...
متن کاملPlant-derived compounds in treatment of leishmaniasis
Leishmaniasis is a neglected public health problem caused by the protozoan species belonging to the genus Leishmania affecting mostly the poor populations of developing countries. The causative organism is transmitted by female sandflies. Cutaneous, mucocutaneous, and visceral clinical manifestations are the most frequent forms of leishmaniasis. Chemotherapy still relies on the use of pentavale...
