Homeoviscous adaptation, growth rate, and morphogenesis in bacteria.
Zaritsky A, Parola AH, Abdah M, Masalha H. Zaritsky A, et al. Biophys J. 1985 Aug;48(2):337-9. doi: 10.1016/S0006-3495(85)83788-7. Biophys J. 1985. PMID: 3902110 Free PMC article.
Sensitivity of exponentially growing populations of Escherichia coli to photo-induced psoralen-DNA interstrand crosslinks.
Grover NB, Margalit A, Zaritsky A, Ben-Hur E, Hansen MT. Grover NB, et al. Biophys J. 1981 Jan;33(1):93-106. doi: 10.1016/S0006-3495(81)84874-6. Biophys J. 1981. PMID: 7023563 Free PMC article.
The first assumes that a cell survives as long as at least one copy of its genome remains undamaged; a variant of this permits repair by DNA strand exchange. The second model allows for a limited period of time during which DNA repair can take place. A

Cell-shape homeostasis in Escherichia coli is driven by growth, division, and nucleoid complexity.
Zaritsky A. Zaritsky A. Biophys J. 2015 Jul 21;109(2):178-81. doi: 10.1016/j.bpj.2015.06.026. Biophys J. 2015. PMID: 26200854 Free PMC article.
Analysis of recently published high-throughput measurements of wild-type Escherichia coli cells growing at a wide range of rates demonstrates that cell width W, which is constant at any particular growth rate, is related (with a CV = 2.4%) to the level of nucleoid c …

Deviation from homeoviscous adaptation in Escherichia coli membranes.
Parola AH, Ibdah M, Gill D, Zaritsky A. Parola AH, et al. Biophys J. 1990 Mar;57(3):621-6. doi: 10.1016/S0006-3495(90)82578-9. Biophys J. 1990. PMID: 2106350 Free PMC article.
This result, implying failure of HA, is now complemented by measurements of DPH lifetimes, which indicate that the dominant variables contributing to the drop in P are (a) the order parameter of the membrane, which goes down, and (b) the fluidity, which may slightly increa …

DNA synthesis in Escherichia coli during a nutritional shift-up.
Zaritsky A, Zabrovitz S. Zaritsky A, et al. Mol Gen Genet. 1981;181(4):564-6. doi: 10.1007/BF00428756. Mol Gen Genet. 1981. PMID: 7022132
DNA synthesis in a thymine-requiring Escherichia coli K12 strain was studied by exploiting deoxyguanosine, so simulating the behaviour of Thy+ strains. DNA synthesis is inhibited during the first 24 min after a nutritional shift-up. The new DNA/mass is lower than th …

Enduring toxicity of transgenic Anabaena PCC 7120 expressing mosquito larvicidal genes from Bacillus thuringiensis ssp. israelensis.
Manasherob R, Otieno-Ayayo ZN, Ben-Dov E, Miaskovsky R, Boussiba S, Zaritsky A. Manasherob R, et al. Environ Microbiol. 2003 Oct;5(10):997-1001. doi: 10.1046/j.1462-2920.2003.00503.x. Environ Microbiol. 2003. PMID: 14510853
Chromosome replication, cell growth, division and shape: a personal perspective.
Zaritsky A, Woldringh CL. Zaritsky A, et al. Front Microbiol. 2015 Aug 3;6:756. doi: 10.3389/fmicb.2015.00756. eCollection 2015. Front Microbiol. 2015. PMID: 26284044 Free PMC article. Review.
Accordingly, the primary signal for cell division transmitted by DNA dynamics (replication, transcription and segregation) to the peptidoglycan biosynthetic machinery is of a physico-chemical nature, e.g., stress in the plasma membrane, relieving nucleoid occlusion in the …

Site-specific recombination in the cyanobacterium Anabaena sp. strain PCC 7120 catalyzed by the integrase of coliphage HK022.
Melnikov O, Zaritsky A, Zarka A, Boussiba S, Malchin N, Yagil E, Kolot M. Melnikov O, et al. J Bacteriol. 2009 Jul;191(13):4458-64. doi: 10.1128/JB.00368-09. Epub 2009 May 8. J Bacteriol. 2009. PMID: 19429625 Free PMC article.
