A Study of Meiosis and the Effects of Certain Antibiotics Upon Meiosis in Gymnosporangium

Cytological Studies on Germinating Teliospores ofHemileia Vastatrix

“…Most of the abnormalities recorded here have been observed by BERLINER (1954) in the case of Gymnosporangium, whose basidia were exposed to some antibiotics. She mentions that the antibiotic substances may have a decided mutagenic potential.…”

Morphology and Cytology of <i>Ravenelia hobsoni</i> Cooke

“…11). Relatively few reports are available regarding details of sequence of prophase stages in rust fungi (Berliner 1954, Pavgi et al 1960, Payak 1957. The diakinesis passes quickly into metaphase and a spindle is formed.…”

Teliospore Germination and Cytological Aberrations in <i>Puccinia sorghi</i> Schw

“…A sharp decline in basidiospore production, branched promycelia and sterig mata, failure in synchronization or delay in nuclear divisions and prolonged associ ation of daughter nuclei is reported as a common feature in the germinated telio spores of Gymnosporangium clavipes Cooke and Peck treated with antibiotics (Berliner 1954). Comparable observations on P. sorghi show a remarkable simil arity.…”
