Ultra low frequency yeast cells electric activity
Cifra, Michal ; Pokorný, Jiří ; Jelínek, František ; Hašek, Jiří ; Šimša, Jan
This paper presents results from the measurement of the electrical activity cold sensitive beta-tubulin mutant tub2-401 of yeast cells in frequency region 0.4 - 1.6 kHz. 25 measurements of both synchronized and nonsynchronized cells show that the synchronized cells have higher electrical activity what corresponds to the findings of Pohl et al. Mechanical oscillations of electrically polar structures in cell may give rise to electric oscillations we measured.

Electromagnetic field around yeast cells
Pokorný, Jiří ; Jelínek, František ; Šaroch, Jaroslav ; Hašek, Jiří ; Palán, B.
Electromagnetic field around synchronized cells of tubulin mutant tub2-401 of Saccharomyces cerevisiae was measured in the M phase of the cell cycle in the frequency range of 8-9 MHz. The measured electromagnetic activity is compared with the evolution of the mitotic spindle. The peaks of the electromagnetic activity seems to coincide with formation of the mitotic spindle, with binding of chromatids to kinetochore microtubules, with anaphase A, and with anaphase B.
