TLDR
The variation in 4C DNA amounts between the species of Calathea was not distinct but in two species of Maranta, a notable variation in nuclear DNA amount was recorded and the amount of nuclear DNA did not show direct correlation with the total chromosome length and volume.Abstract:
Karyological analysis including determination of somatic chromosome number, total chromosome length, volume and karyotype formula andin situ estimation of 4C-nuclear DNA amount were carried out on 14 different species and varieties of the generaCalathea, Maranta andStromanthe. The 4C nuclear DNA amount was estimated through Feulgen microspectrophotometry following single wavelength method and expressed in arbitrary units of relative absorbances. The variation in 4C DNA amounts between the species ofCalathea was not distinct but in two species ofMaranta, a notable variation in nuclear DNA amount was recorded. In addition, the amount of nuclear DNA did not show direct correlation with the total chromosome length and volume. The absence of wide difference in nuclear DNA content at an interspecific level might have some adaptive value.read more

Nuclear DNA Amounts in Angiosperms and their Modern Uses—807 New Estimates
TL;DR: This paper lists DNA C-values for 807 angiosperm species from 70 original sources, including 520 from sources published after 1996, and 691 for species not included in any of the previous five lists.

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.

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.

Dysploidy and polyploidy trigger strong variation of chromosome numbers in the prayer-plant family (Marantaceae)
TL;DR: Dysploid variation, polyploidy and, to a lesser extend, hybridization may be the main factors in chromosome number evolution of the family Marantaceae.

DNA Synthesis and Cell Division in Germinating Onion: III. Variation in Apparent Feulgen-DNA Content with Nuclear area Change
TL;DR: Careful microspectrophotometric analysis of the 2C (Gl) nuclear population of the onion during the critical period of decompaction from the quiescent to the functional state reveals an increase in apparent DNA content correlated with increased nuclear area.

Cytophotometric Measurement of DNA, Total Proteins and Histone in the Nuclei of Triticum Dicoccum, Aegilops Longissima and their Amphydiploid
G. Martini,A. Brunori +1 more
TL;DR: Cytophotometric analysis of isolated nuclei in Triticum dicoccum, Aegilops longissima and their amphydiploid has shown that the DNA, total protein and histone contents are the sum of the nuclear contents of the same compounds in the two parent species.
