Heterocyst differentiation and cell division in the cyanobacterium Anabaena cylindrica: effect of high light intensity.
Heterocyst differentiation in the cyanobacterium Anabaena cylindrica is initiated by the removal of fixed nitrogen from the medium. These specialized cells occur singly at regular intervals within filaments of vegetative cells. Incubation of cultures for periods of up to 12 h immediately prior to or following removal of fixed nitrogen, at a light intensity (500 mi Einsteins cm-2 s-1) approximat...
متن کاملTumors Induced by Viruses: Ultrastructural Studies
A great responsibility is borne by those who determine what level of radiation exposure to man can be regarded as permissable in modern civilization. A value set too high could lead to an excessive load of deleterious mutations in the human genome that we all carry, while a value set too low will prove costly and time consuming to maintain. This book is written by Dr. John F. Loutit who played ...
متن کاملUltrastructural localization of osteopontin in the kidney: induction by lipopolysaccharide.
Osteopontin is a secreted phosphoprotein that is expressed in the normal kidney and induced during various pathologic conditions associated with tubulointerstitial injury. However, the exact cellular location of osteopontin in the kidney has been a matter of controversy, and little is known about the role of osteopontin in the kidney. The purpose of this study was to establish the cellular and ...
متن کاملStudies on Nitrogen Fixation by Blue-green Algae I. Nitrogen Fixation by Anabaena Cylindrica Lemm
RECENT work, particularly that of De (1939), has shown that some blue-green algae are capable of utilizing the free nitrogen of the atmosphere in the synthesis of cell material. Much further work will be necessary, however, before the importance of nitrogen fixation by these organisms in nature can be estimated, our knowledge both of the distribution of the property within the group of the Myxo...
متن کاملUltrastructural studies on mitochondrial swelling.
Mitochondrial swelling induced by valinomycin, calcium chloride and P(i) was studied after potassium permanganate fixation in suspension. Valinomycin induces a rapid K(+) influx, increase of the matrix space and out-folding of the cristae, with good preservation of the matrix material. This swelling is reversible but the cristae do not completely re-form and have a blebbed appearance. On repeat...
