Cytological Effects of Some Antibiotics

Influence of Gamma Rays on Cell Division in the Seed Roots of Irradiated Dry Seeds of <i>Vince rosea</i> L

“…This type of grouping in root tips has been noticed by Wilson et al (1950) in chemically treated materials. Wilson et al (1951) suggest that there are two or more independent components which control the metaphase orientation of chromosomes and their metaphase movement.…”

“…The existence of "metabolic imbalance" may be further supported by the occurrence of the aggregation of chromosomes in different groups at metaphase and anaphase as well as failure of pre-and postmetaphase movement of chromosomes in several dividing root tip cells of the irradiated seeds of Vinca rosea L. Similar abnormal behaviour of chromosomes has been induced in the dividing cells treated with antibiotics and chemicals by previous workers (Wilson 1950, Matsuura and Iwabuchi 1962and Sharma and Dutta 1962. This type of grouping in root tips has been noticed by Wilson et al (1950) in chemically treated materials.…”

Comparative cytological studies of the effect of some aliphatic alcohols and the fatty alcohols from Euphorbia granulata and Pulicaria crispa on mitosis of Allium cepa.

“…The somatic reduction observed was similar to that observed after treatments with various agents such as colchicine and sodium nucleate (Allen, Wilson and Powell 1950), various antibiotics (Wilson 1950) and glycosides of Nerium oleander (Tarkowska 1971b).…”

The Effect of Cycloheximide on Cell Division in Partially Synchronized Plant Cells

“…3). Wilson (1950) first observed the effect of cycloheximide on chromosome coiling and termed it "supercontraction". There were a small number of blocked prophases with a nuclear envelope and supercontracted chromosomes, but without a nucleolus (Fig.…”

“…INTRODUCTION The effect of the antibiotic cycloheximide on mitosis in plant cells was first reported by Wilson (1950). This and subsequent studies in onion (Hawthorne and Wilson 1952) and pea roots (Bowen and Wilson 1954;Hadder and Wilson 1958) indicated that the two most conspicuous effects were mitotic inhibition and the formation of deviant prophases.…”
