We have developed a DNA extraction procedure for milligram amounts of plant tissue.
Yields ranged from 0.3–200 nanograms of DNA per milligram of tissue. The factors affecting …

Two DNA binding guanine-specific antibiotics, chromomycin A 3 (CMA) and the closely
related mithramycin (MM), were used as chromosome fluorescent dyes. Root-tip metaphase …

Both rDNA gene multiplicity and genome size vary widely among eukaryotes. For some time,
there has been debate regarding any possible relationship between these two parameters …

Ribosomal RNA genes in plants are highly variable both in copy number and in intergenic
spacer (IGS) length. This variability exists not only between distantly related species, but …

Publisher Summary This chapter focuses on genomic size evolution in animals. There are
many ways of studying the evolution of genome. The chapter looks on the examination of …

Background In studies looking at individual polyploid species, the most common patterns of
genomic change are that either genome size in the polyploid is additive (ie the sum of …

Abstract Background Nicotiana sylvestris and Nicotiana tomentosiformis are members of the
Solanaceae family that includes tomato, potato, eggplant and pepper. These two Nicotiana …

Background 45S rDNA sites are the most widely documented chromosomal regions in
eukaryotes. The analysis of the distribution of these sites along the chromosome in several …
