Plasticity of the tobacco genome was studied by testing the DNAs of protoplast-derived regenerants with three different repetitive DNA sequences by the method of quantitative DNA/DNA hybridizations. A large population of 91 regenerants belonging to 3

A study was made of the SOS induction of the gene sulA of Escherichia coli K12 in relation to the gene dosage of the gene recA. In experiments the sulA::lacZ fusion strain PQ37 and derivatives of PQ37 with the multi-copy plasmids pDR1453 or pBR322 we

Several simple furan and nitrofuran compounds were tested for mutagenicity and related biological activities, in the Ames test, the bacterial repair test, the prophage-induction test and the chloroplast-bleaching test. Only those compounds having the

Using SDS-polyacrylamide gel electrophoresis to study the early expression of P22 genes we show that early expression of the ant-gene (imm I region) is turned off after 6-8 min, independent of the 'late' acting mnt-repressor. A semi-clear mutant call

The composite transposon Tn 3(lac+ carried by the wide-host range conjugative plasmid R772 was transferred from Escherichia coli into Agrobacterium tumefaciens. We showed that the lac operon was expressed and inducible in A. tumefaciens independently

The effects were studied of three clear plaque mutations of phage P22 (cir4-1, cir5-1 and cir6-1) on antirepressor synthesis. The mutant site cir4-1 has no influence on the expression of gene ant. The cir5-1 and cir6-1 mutations prevent the repressio

It is proposed that the transcription of the c-2 repressor gene initiates at two promoters, pre and prm, similarly to the transcription of the c-I gene of lambda phage. In the P22 phage, these promoters are defined by mutations of c54 and K5.

Unlike in most bacterial species, so far studied synthesis of DNA inLactobacillus acidophilus R-26 continues even in the absence of protein synthesis or in the absence of essential amino acids, the increase of DNA under these conditions being 100–1

Thymineless death (TLD) as well as deoxyribosideless death (DRLD) can be observed inLactobacillus acidophilus R-26 during growth in media lacking thymine or deoxyriboside respectively. Both phenomena exhibit the same interval of lage period (2–3 h)
