Electron microscopic study of the process of DNA ejection from the head of PL-1, a Lactobacillus casei phage. 1987

K Watanabe, and T Fukuzaki, and M Hayashida, and Y Nakashima

The process of DNA ejection from the head of PL-1, a Lactobacillus casei ATCC 27092 phage, was studied by electron microscopy by counting the number of ghost particles with empty heads among phages already adsorbed to the cell. The process of DNA ejection was temperature- and live cell-dependent.

UI MeSH Term Description Entries
D007780 Lacticaseibacillus casei A rod-shaped bacterium isolated from milk and cheese, dairy products and dairy environments, sour dough, cow dung, silage, and human mouth, human intestinal contents and stools, and the human vagina. L. casei is CATALASE positive. Lactobacillus casei
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D004279 DNA, Viral Deoxyribonucleic acid that makes up the genetic material of viruses. Viral DNA
D001435 Bacteriophages Viruses whose hosts are bacterial cells. Phages,Bacteriophage,Phage
D013696 Temperature The property of objects that determines the direction of heat flow when they are placed in direct thermal contact. The temperature is the energy of microscopic motions (vibrational and translational) of the particles of atoms. Temperatures
