Chromosome evolution in the genus Ophioglossum L.
TLDR
The neobasic number, n= 120, appears to have arisen through various combinations and permutations of these, theoretically 2401 routes; only a relatively few of these routes exist today, suggesting that extreme selection has been exerted against the majority, and further suggesting that Ophioglossum represents an evolutionary dead end through repeated cycles of polyploidy and is possibly at the verge of extinction.About:

Interpretation of karyotype evolution should consider chromosome structural constraints.
Ingo Schubert,Martin A. Lysak +1 more
TL;DR: This work interprets evolutionary genome alterations in a parsimonious way and demonstrates that results of comparative genomics and comparative chromosome painting can be explained on the basis of known primary and secondary chromosome rearrangements.
Journal ArticleDOI
Evolution of DNA amounts across land plants (embryophyta)
TL;DR: It is apparent that this dynamic pattern of genome size evolution is repeated on a broad scale across land plants.
Book ChapterDOI
The Incidence of Polyploidy in Natural Plant Populations: Major Patterns and Evolutionary Processes
TL;DR: Surprisingly, many accepted trends between polyploidy and geography, mating system, and comparative rates of species diversification have become less strong or conflicting with the development of new procedures, in particular with phylogenetic approaches.

Ecological and genetic factors linked to contrasting genome dynamics in seed plants.
Andrew R. Leitch,Ilia J. Leitch +1 more
TL;DR: The genomic structure and evolution of angiosperms and gymnosperms are compared and compared and it is found that angiosperm genomes are more dynamic and diverse, particularly amongst the herbaceous species.

Genome Size Diversity and Evolution in Land Plants
Ilia J. Leitch,Andrew R. Leitch +1 more
TL;DR: This chapter provides an overview of what is currently known about the diversity of genome sizes encountered in land plant groups and considers how such diversity might have evolved.
