Chromosome counts in a polyploid series of Saccharomyces.
Direct determination of chromosome number in Saccharomyces is advantageous in the further development of yeast genetics. The enumeration of centromeres by deductions from tetrad analysis sets a minimum chromosome number (Lindegren, 1949; Lindegren and Lindegren, 1951b), but interchromosomal linkage (Shult and Lindegren, 1955) introduces complexities into the deduction of chromosomal numbers fro...
متن کاملCHROMOSOME COUNTS IN SOME MOSSES OF IRAN
Cytological information is absolutely lacking for the Iranian moss flora (Bryophytes). The present research, dealing with cytological studies on the following five species (including two expressions and one variety) of Iranian mosses, namely, Amblystegium riparium (Hedw.) B.S.G. “brevipes” expression(n=20), A. riparium (Hedw.) B.S.G. “pennellii” expression (n=9, 9+m, 9+2m), A. serpens (Hedw.) B...

15 صفحه اولChromosome pairing in polyploid cells.
The homologues in polyploid metaphases of air-dried suspensions of cultured cells are usually seen closely paired as diplochromosomes ("endore duplicated" cells) or unpaired as randomly distributed chromosomes ("poly ploid" cells). More often we find another configuration, a mixture of paired and unpaired chromosomes in the same metaphase, and describe here the conditions under which it appears...
متن کاملThe nucleus of Saccharomyces; a cytological study of a frozen-dried polyploid series.
Identification of the yeast nucleus, and particularly a resolution of its mitotic cycle, can scarcely be considered to have yielded unanimous agreement. In spite of a voluminous cytological literature, little has been established with certainty in regard to the identity, morphology, or numbers of chromosomes, or in regard to the orientation of the dividing nucleus with respect to the centrosome...
