Chromosome Studies on <i>Trillium kamtschaticum</i> Pall

Maedi - visna PALL

Rise in temperature is not observed in visna or maedi. The animals seem to be remarkably alert and the appetite remains unaffected throughout. The period between inoculation of infective visna material and the development of clinical signs varies from animal to animal even with a standard dose. Usually this period is very long and several months to several years may elapse before clinical signs...

CHROMOSOME STUDIES OF IRANIAN MEMBERS OF TRIBE SOPHOREAE (FAMILY LEGUMINOSAE

The tribe Sophoreae sensu Polhill [9,10] is a large and diverse assemblage comprising the ancient and primitive ancestral stocks of Papilionoideae. The most frequent chromosome basic numbers in this tribe are x = 11 and x = 9 but chromosome numbers range from x = 8-14 are also known. In this study chromosome numbers and karyotype variation of Iranian members of tribe Sophoreae are reported. Ira...

Karyotype and pattern of chromosome replication in Lagurus lagurus Pall (Cricetidae, Microtinae).

The potential value of chromosome characters in mammalian taxonomy has been limited by the inadequate knowledge of the chromosomes of various species listed by the systematists (Makino 1951). In recent years some cytologists have become interested in studying the karyotype of different mammalian species (Klinger 1963, Nadler 1965). In addition, the need for detailed knowledge about the karyotyp...

Sex Chromosome Aneuploidy: Prospective Studies on Children

This two-volume publication contains the proceedings of a NATO Advanced Study Institute, held in April 1978. The material is organized in five sections. In the first section J. Bonner presents a historic review of chromatin research. The following section describes biophysical and chemical methods used in the study of isolated chromatin, such as electron microscopy, circular dichroism, X-ray di...
