Streptomycin-resistant Plants from Callus Culture of Haploid Tobacco
TLDR
Conditions are worked out for the isolation of streptomycin-resistant tobacco cell lines, from which diploid fertile plants carrying the streptomecin- resistant character, were regenerated and seedlings grown from seeds of self-fertilized resistant Str-r1 plants were resistant.Abstract:
THERE are few reports of the isolation of biochemical mutants from cultured plant cells1–3. We know of none describing plants which have been regenerated from these mutant cell lines and which still carry the mutant trait. We have worked out conditions for the isolation of streptomycin-resistant tobacco cell lines, from which diploid fertile plants carrying the streptomycin-resistant character, were regenerated. Seedlings grown from seeds of self-fertilized resistant Str-r1 plants were also resistant. The progeny obtained from crosses of Str-r1 plants and streptomycin sensitive (Str-s) plants showed non-Mendelian, uniparental transmission of the resistance trait.read more

TL;DR: Transgenic plants showed complete resistance towards high doses of the commercial formulations of phosphinothricin and bialaphos, presenting a successful approach to obtain herbicide‐resistant plants by detoxification of the herbicide.

Induction of male sterility in plants by a chimaeric ribonuclease gene
TL;DR: Chimaeric ribonuclease genes that are expressed in the anthers of transformed tobacco and oilseed rape plants were constructed to facilitate the production of hybrid seed in various crop plants.

TL;DR: Plants regenerated from transformed cell lines were phenotypically normal and fertile, and they maintained and expressed the foreign gene throughout the development of vegetative and generative organs.

Stable transformation of plastids in higher plants
TL;DR: Stable genetic transformation of the plastid genome is reported in a higher plant, Nicotiana tabacum, obtained after bombardment of leaves with tungsten particles coated with pZS148 plasmid DNA.

TL;DR: The results demonstrate that foreign genes are not only transferred but are also functionally expressed when the appropriate constructions are made using promoters known to be active in plant cells.

Karyotypic changes in callus cultures from haploid and diploid plants of Crepis capillaris (L.) Wallr
TL;DR: Two auxin-heterotrophic callus cultures of Crepis capillaris were studied and it has been found that new karyotypes also originate through chromosome rearrangements at the same ploidy level as the original explant.

Induction and Isolation of Auxotrophic Mutants in Somatic Cell Cultures of Nicotiana tabacum
TL;DR: A method for the selection of auxotrophic mutants from somatic cell cultures of Nicotiana tabacum depends upon the incorporation of 5-bromodeoxyuridine into the DNA of wild-type cells and upon its lack of incorporation into theDNA of Auxotrophic cells.
