Cytology of Teliospore Germination and Basidiospore Formation in Uromyces appendiculatus
The cytology of teliospore germination and basidiospore formation in Urornyces appendiculatus vat. appendieulatus was characterized with light and fluoroscence microscopy. Meiosis of the diploid nucleus occurred in the metabasidium. The four haploid daughter nuclei migrated into the basidiospore initials where they underwent a post meiotic mitosis. Each basidiospore was delimited from the meata...
متن کاملDifferences in teliospore germination patterns of Microbotryum violaceum from European and North American Silene species
Microbotryum violaceum (anther-smut) from Silene caroliniana and S. virginica produced promycelia that frequently appeared to contain more than three cells according to the number of septations. This is in contrast to samples from S. latifolia and to previous descriptions of this species. Apparent four-celled promycelia contained three nucleate cells and one anucleate zone. Anucleate zones were...
متن کاملActivation of Teliospore Germination in Uromyces appendiculatus var. appendiculatus. I. Aging and Temperature
The effects of aging and temperature on teliospore germination in Uromyces appendiculatus var. appendiculatus were studied. 1. Indoor storage was good at ~ 4 QC in the dirk. Under these conditions spores remained dormant for ~ 9 mo, but thereafter germination gradually increased to a maximum (~ 63 %) after 36 moo Spores .9tored outdoors showed a marked increase in germination after ~ 4 mo and r...
متن کاملActivation of Teliospore Germination in Uromyces appendiculatus var. appendiculatus. II. Light and Host Volatiles
The effects of light and host volatiles on teliospore germination in Uromyces appendiculatus var. appendiculatus were studied. I. Light intensities ranging 15-26000 lux supported teliospore germination and basidiospore formation. The optimum light intensity was 17000 lux under the described conditions. Light-dark alternation was necessary for teliosp.ore germination: no germination occurred und...
متن کاملCytological Aberrations in Cultures of "normal" Monkey Kidney Epithelial Cells
A cytological study was made of short term primary cultures of monkey kidney epithelial cells grown in serum-containing (M-H) and synthetic (SM-2) media. The mitotic activity of the cultures reached a peak 3 to 5 days after seeding, and rapidly declined if the medium was not changed. With replenishment at 48 hour intervals a high mitotic rate was maintained through the 8th day. Cultures subject...
