The Natural Variation in Six Populations of Calendula officinalis L.: A Karyotype Study
In the current investigation, karyotype analysis and chromosome characteristics of six populations of Calendula officinalis L.(pot marigold) from Iran are studied. Results showed that all populations were diploid (2n= 2x= 32), and had symmetrical karyotypes composing mainly of metacentric and submetacentric chromosomes. The mean chromosome length ranged from 1.05 in Karaj to 1.50 μm in...

متن کاملPrognostic value of monosomal karyotype in comparison to complex aberrant karyotype in acute myeloid leukemia: a study on 824 cases with aberrant karyotype.
In acute myeloid leukemia (AML) the subset with complex karyotype (CK) is traditionally regarded as the worst prognostic group. However, ≥ 3, ≥ 4, or ≥ 5 abnormalities have been variably used for its definition. Recently, monosomal karyotype (MSK) was suggested to indicate an even inferior outcome. We tested which definition fits best to identify the most unfavorable subgroup. After excluding p...
