Role of Two Cell Wall Amidases in Septal Junction and Nanopore Formation in the Multicellular Cyanobacterium Anabaena sp. PCC 7120

Autor: Jan Bornikoel, Alejandro Carrión, Qing Fan, Enrique Flores, Karl Forchhammer, Vicente Mariscal, Conrad W. Mullineaux, Rebeca Perez, Nadine Silber, C. Peter Wolk, Iris Maldener

Publikováno v: Frontiers in Cellular and Infection Microbiology, Vol 7 (2017)

Filamentous cyanobacteria have developed a strategy to perform incompatible processes in one filament by differentiating specialized cell types, N2-fixing heterocysts and CO2-fixing, photosynthetic, vegetative cells. These bacteria can be considered

Analysis of a Het- mutation in Anabaena sp. strain PCC 7120 implicates a secondary metabolite in the regulation of heterocyst spacing

Autor: Todd A. Black, C P Wolk

Publikováno v: Journal of Bacteriology. 176:2282-2292

Transposon-generated mutant N10 of Anabaena sp. strain PCC 7120 has a Het- phenotype (A. Ernst, T. Black, Y. Cai, J.-M. Panoff, D. N. Tiwari, and C. P. Wolk, J. Bacteriol. 174:6025-6032, 1992). Reconstruction of the transposon mutation reproduced a H

Role for hetC in the Transition to a Nondividing State during Heterocyst Differentiation in Anabaena sp

Autor: X Xu, C P Wolk

Publikováno v: Journal of Bacteriology. 183:393-396

Nitrogen-deprived filaments of wild-type or hetC Anabaena sp. produce respectively, at semiregular intervals, heterocysts and weakly fluorescent cells. Unlike heterocysts, the latter cells can divide and elongate, producing a pattern of spaced series

A transposition-induced mutant of Nostoc ellipsosporum implicates an arginine-biosynthetic gene in the formation of cyanophycin granules and of functional heterocysts and akinetes

Autor: Francisca Fernández-Piñas, C P Wolk, Francisco Leganés

Publikováno v: Scopus-Elsevier

In strain NE1 of Tn5-1058-mutagenized Nostoc ellipsosporum, the transposon was found within a gene whose translation product is similar in amino acid sequence to the arginine-biosynthetic protein N-acetylglutamate semialdehyde dehydrogenase encoded b

hetC, a gene coding for a protein similar to bacterial ABC protein exporters, is involved in early regulation of heterocyst differentiation in Anabaena sp. strain PCC 7120

Autor: I Khudyakov, C P Wolk

Publikováno v: Journal of Bacteriology. 179:6971-6978

Transposon-generated mutant C3 of Anabaena sp. strain PCC 7120 is unable to form heterocysts upon deprivation of combined nitrogen but forms a pattern of spaced, weakly fluorescent cells after 2 days of deprivation. Sequence analysis of chromosomal D

Nitrogen deprivation of Anabaena sp. strain PCC 7120 elicits rapid activation of a gene cluster that is essential for uptake and utilization of nitrate

Autor: Y Cai, C P Wolk

Publikováno v: Journal of Bacteriology. 179:258-266

A transposon bearing luxAB, encoding luciferase, as a reporter of transcription was used to identify genes that are activated rapidly upon deprivation of Anabaena sp. strain PCC 7120 of fixed nitrogen. The three transposon-marked loci that were ident

Publikováno v: Journal of Bacteriology. 176:5059-5067

pEC22 is a small plasmid that encodes the restriction-modification system MR.EcoT22I. Restriction and functional analysis of the plasmid identified the positions of genes encoding that system. The plasmid is able to be conducted by conjugal plasmids,
