TLDR
Investigation on karyotype, 4C nuclear DNA amount and interphase nuclear volume (INV) of different HimalayanBupleurum species belonging to Umbelliferae revealed genetic differentiation.Abstract:
Investigation on karyotype, 4C nuclear DNA amount and interphase nuclear volume (INV) of different HimalayanBupleurum species belonging toUmbelliferae revealed genetic differentiation. Numerical and structural alternation of chromosomes in interspecific level were manifested in their statistically significant altered species specific 4C nuclear DNA content. Somatic chromosome number ranged between 2n = 14 and 2n = 16.B. himalayense was reported for the first time having 2n = 16 chromosomes. Correlation coefficient among the various chromosomal and nuclear parameters showed no significant progressive or regressive interdependence except in between INV and nuclear DNA amount. Critical differences between 4C DNA content showed interspecific variation.read more

TL;DR: Evidence from morphology, crossability, pollen viability and chromosome synapsis suggests a segmental allopolyploid origin for M. cymbalaria, a taxon of controversial taxonomic identity of the Momordica genus.

Estimation of 4C DNA and Karyotype Analysis in Ginger (Zingiber officinale Rosc.) -I
Anath Bandhu Das,S. Rai,P. Das +2 more
TL;DR: The structural alteration of chromosomes as well as loss or addition of highly repetitive sequences in the genome showed variation in the DNA amount at cultivar level, but a marginal variation in nuclear DNA content at the cultivarlevel indicated a close relationship between them.

Identification of RAPD markers, in situ DNA content and structural chromosomal diversity in some legumes of the mangrove flora of Orissa
TL;DR: By employing RAPD markers, karyotypes and 4C DNA content analysis, the present study has helped to resolve the relationship between the taxonomically diverse leguminous mangroves and study their ability to coexist with mangrove that would shed light on the evolution ofMangroves from terrestrial species.

Molecular phylogeny of Heritiera Aiton (Sterculiaceae), a tree mangrove: variations in RAPD markers and nuclear DNA content
TL;DR: Random amplified polymorphic DNA (RAPD) markers are used to estimate interspecific variation among mangrove and non-mangrove Heritiera fomes, H. littoralis and H. macrophylla to find characteristic molecular markers in H. Macrophylla, a species from a non-reproductive habitat.

Radiation response of dry seeds in two varieties of Triticum durum.
TL;DR: DNA cytophotometric analyses of prophases (4C) in growing root tips of two varieties of durum wheat showed that the variety Aziziah has a DNA content per nucleus 6% higher than Cappelli, which in turn has a larger nuclear volume.

Nuclear volume, nuclear dna content and radiosensitivity in brassica and allied genera
TL;DR: Relationships between nuclear volume, nuclear DNA content and radiosensitivity were studied on genera of a family, species of a genus, and strains a species to observe the radiosensitivity was more markedly correlated with the mean DNA content per chromosome than with the estimated interphase chromosome volume.

Variation in 4C DNA Content and Chromosome Characteristics in Different Varieties of Coriandrum sativum L
Anathbandhu Das,Ranajit Mallick +1 more
TL;DR: The absence of wide differences in nuclear DNA content in the varietal level indicate a close relationship between Coriandrum sativum L. and 4C, which have played a vital role in intervarietal DNA variation.
