Symbiotic Mutants of Rhizobium Meliloti Which Produce Non-Succinylated Exopolysaccharide
TL;DR: These mutants were isolated on the basis of their non-fluorescent colony phenotype on agar medium containing the fluorescent stain calcofluor and three of the loci defined by these mutants were shown to reside in a cluster on the megaplasmid pRmeSU47b.
Journal ArticleDOI
Lighting torches in the DNA repair field: development of key concepts
TL;DR: This review traces some of the critical concepts concerning DNA repair and biological responses to DNA damage that have developed since that time, highlighting ways in which Phil Hanawalt has provided leadership in the field at many different levels.
Nucleotide Sequence oftheSalmonella typhimurium mutLGene Required forMismatch Repair: Homology ofMutLtoHexBof Streptococcus pneumoniae andtoPMS1oftheYeast
TL;DR: ThemutLgene ofSalmonella typhimurium LT2 is required fordam-dependent methyl-directed DNA mismatch repair, and the presence of excess amounts of this fusion protein in wild-type mutL+cells resulted in a trans-dominant effect causing thecell to exhibit a highspontaneous mutation frequency.
Identification ofpKM101-Encoded LociSpecifying Potentially Lethal GeneProducts
TL;DR: A number of plasmic loci have been found tocontain genes whose products arepotentially lethal to thebacterial host, and thesegeneshave beenimplicated inenhancing plasmid stability bycoupling hostcell division toplasmid replication.
The Mode of Incorporation of 6-Benzylaminopurine into Tobacco Callus Transfer Ribonucleic Acid
TL;DR: In this article, the incorporation of the synthetic cytokinin, N6-benzyladenine, into the transfer RNA of tobacco callus tissue was shown to involve the intact moiety.
