Genetic Transformation in Yeasts [PDF]
Journal of General Microbiology, 1974 SUMMARY: The transformability of 25 strains of yeasts belonging to 23 species in three genera - Saccharomyces, Hansenula and Candida - was investigated with respect to ten characters. Eighteen hour cultures at about the end of the log phase of growth, addition of 10 μg DNA/ml, and an incubation time of 30 min at 30 to 37 °C usually yielded best results.

First Steps towards Underdominant Genetic Transformation of Insect Populations [PDF]
, 2014 The idea of introducing genetic modifications into wild populations of insects to stop them from spreading diseases is more than 40 years old. Synthetic disease refractory genes have been successfully generated for mosquito vectors of dengue fever and ...

Insights into the genetic influences of the microbiota on the life span of a host
Frontiers in Microbiology, 2023 Escherichia coli (E. coli) mutant strains have been reported to extend the life span of Caenorhabditis elegans (C. elegans). However, the specific mechanisms through which the genes and pathways affect aging are not yet clear.

Genetic Transformation in Rhizobium [PDF]
Journal of General Microbiology, 1969 SUMMARY: Mutants of ground nut (Rhizobium cowpea group) strain gr3 were isolated using ultraviolet radiation and N-methyl-N'-nitrosoguanidine (NTG) as mutagenic agents. An adenine-requiring mutant was used as the recipient and its wild type as the donor in transformation studies. Initially minimal medium supplemented with 2 μg. adenine/ml. was used for

Genetic Transformation in Pseudomonas [PDF]
Journal of General Microbiology, 1967 SUMMARY: Intraspecific and interspecific transformation in Pseudomonas has been investigated. Two isoleucine+valine requiring mutants of Pseudomonas aeruginosa have been transformed to prototrophy. By using gelatin liqui-faction as a marker character it was observed that two strains of P. fluorescens, a phytopathogen P.

Transformation-Interaction-Rational Representation for Symbolic Regression [PDF]
, 2022 Symbolic Regression searches for a function form that approximates a dataset often using Genetic Programming. Since there is usually no restriction to what form the function can have, Genetic Programming may return a hard to understand model due to non-linear function chaining or long expressions.
