Chromosome Number Variation in Iranian Populations of Acorus calamus

Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...

Morpho-phenology and chromosome number of Iranian Bromus danthoniae Trin. genotypes

ABSTRACT- Bromus danthoniae Trin. is an annual grass species which grows mainly on dry grassy rocky mountain slopes and grassy steppe, and is grazed by many herbivores and recognized as a useful pasture plant. The chromosome number, morphological and anatomical traits of 82 genotypes of B. danthoniae belonging to three sub-taxa were investigated. Twenty-seven quantitative and 20 qualitative mor...

Mechanisms of Chromosome Number Evolution in Yeast

The whole-genome duplication (WGD) that occurred during yeast evolution changed the basal number of chromosomes from 8 to 16. However, the number of chromosomes in post-WGD species now ranges between 10 and 16, and the number in non-WGD species (Zygosaccharomyces, Kluyveromyces, Lachancea, and Ashbya) ranges between 6 and 8. To study the mechanism by which chromosome number changes, we traced t...

Inheritance of chromosome number in pigs.

(Received 23rd January 1968, revised 25th May 1968) Summary. All possible crosses were made between European wild pigs with either 36 or 37 chromosomes and domestic swine with 38. The 36 \m=x\36 cross produced only pigs with 36; the 36 \m=x\37 and 37 \m=x\38 crosses yielded the parent numbers in about equal numbers of pigs. All pigs resulting from the 36\m=x\38cross had 37, while crossing 37\m=...
