Nonchromosomal antibiotic resistance in bacteria: genetic transformation of Escherichia coli by R-factor DNA.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1972
Transformation of E. coli cells treated with CaCl(2) to multiple antibiotic resistance by purified R-factor DNA is reported. Drug resistance is expressed in a small fraction of the recipient bacterial population almost immediately after uptake of DNA ...

Genetic Transformation in Conifers [PDF]

open access: yes, 1999
Several attempts at the genetic improvement of tree species have been made, but in comparison with crop plants the efforts as well as the results have been rather limited. The most commonly used approaches have involved selection of superior genotypes from natural outbred populations, mutations, and intra- and inter-specific hybridization under ...

Ethylene production in plants during transformation suppresses vir gene expression in Agrobacterium tumefaciens [PDF]

open access: yes, 2008
•Ethylene evolution from plants inhibits Agrobacterium-mediated genetic transformation, but the mechanism is little understood. In this study, the possible role of ethylene in Agrobacterium-mediated genetic transformation was clarified.•It was tested ...

Approaches to genetic tool development for rapid domestication of non-model microorganisms

open access: yesBiotechnology for Biofuels, 2021
Non-model microorganisms often possess complex phenotypes that could be important for the future of biofuel and chemical production. They have received significant interest the last several years, but advancement is still slow due to the lack of a robust

Tumor Analyses Reveal Squamous Transformation and Off-Target Alterations As Early Resistance Mechanisms to First-line Osimertinib in EGFR-Mutant Lung Cancer

open access: yesClinical Cancer Research, 2020
Purpose: Patterns of resistance to first-line osimertinib are not well-established and have primarily been evaluated using plasma assays, which cannot detect histologic transformation and have differential sensitivity for copy number changes and ...

Genetics of Follicular Lymphoma Transformation

open access: yesCell Reports, 2014
Follicular lymphoma (FL) is an indolent disease, but 30-40% of cases undergo histologic transformation to an aggressive malignancy, typically represented by diffuse large B cell lymphoma (DLBCL). The pathogenesis of this process remains largely unknown.

Establishment of Hevea brasiliensis lines overexpressing genes involved in ethylene signalling pathway [PDF]

open access: yes, 2016
The gaseous plant hormone ethylene has a wide variety of applications in agriculture and horticulture. Ethylene Response Factors (ERF) are the last transcription factors of the ethylene signalling pathway and control a large number of ethylene-responsive

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.

Efficiency of Genetic Transformation Via Pollen-Tube Pathway of Jatropha (Jatropha Curcas L.) Based on Histochemical and Molecular Analysis [PDF]

open access: yes, 2017
The genetic transformation via pollen-tube pathway is an alternative method to overcome the constraints imposed by genotype specificity in transformation and regeneration in jatropha (Jatropha curcas L.) tissue culture.

From “the dialectics of nature” to the inorganic gene [PDF]

open access: yes, 1999
The concept of projection from one space to another, with a consequent loss of information, can be seen in the relationships of gene to protein and language description to real situation.
