The Evolution of Chromosome Arrangements in Carex (Cyperaceae)
TLDR
An integration of biosystematic, cytogenetic, and genomic studies across the Cyperaceae will be needed to address the question of what role chromosome evolution plays in species diversification within Carex and the CyPeraceae as a whole. Expand
Broad variation in rates of polyploidy and dysploidy across flowering plants is correlated with lineage diversification
TLDR
An overview of angiosperm chromosomal evolution and a roadmap for future research on the complex relationships among polyploidy, dysploidsy, and diversification across the angiosperms are provided. Expand
Cyperaceae in a data‐rich era: New evolutionary insights from solid frameworks
Cyperaceae are among the 10 most diverse angiosperm families and the third largest among monocots (Christenhusz & Byng, 2016), with a critical ecological role in wetlands and in high‐latitude andExpand
Meiotic analysis in some species of family Cyperaceae from North India
TLDR
During the present investigation, in some meiotic cells of Cyperus difformis and Isolepis setacea, chromatin threads were found which were typical for the species with inverted meiosis, giving the idea of the presence of inverted meiotic in these two genera. Expand
Chromosome numbers of Carex (Cyperaceae) and their taxonomic implications
TLDR
The results of this study indicate that the position of C. cilicica in Aulocystis section may raise doubts, and attention was paid to the relationship between C. phyllostachys and taxa of the subgenus Carex section Gynobasidae. Expand
Inferring hypothesis-based transitions in clade-specific models of chromosome number evolution in sedges (Cyperaceae).
TLDR
The role of chromosomal rearrangements on lineage diversification is elucidated by analyzing a new comprehensive sedge (Cyperaceae) phylogenetic tree and a complex, heterogeneous model composed of different clade-specific chromosome evolution transitions are significantly supported against the null hypothesis. Expand
Aneuploidy in Cyperus tenuispica from North India
TLDR
Three populations of Cyperus tenuispica Steud belonging to family Cyperaceae were collected from different localities of North India and revealed the existence of two cytotypes with n=8 in two populations and with n-7 in one population. Expand
Agmatoploidy and symploidy: a critical review

TLDR
A critical review of the literature shows that examples of chromosome number doubling by agmatoploidy are rare and not clearly demonstrated, and it is proposed here that these terms should be avoided or even abolished. Expand
Chromosomal rearrangements in holocentric organisms lead to reproductive isolation by hybrid dysfunction: The correlation between karyotype rearrangements and germination rates in sedges.
PREMISE OF THE STUDY Understanding the drivers of speciation is a central task of evolutionary biology. Chromosomal rearrangements are known to play an important role in species diversification, butExpand

On the morphology of the chromosome group in Brachystola magna
TLDR
A critical examination of large numbers of dividing cells is conducted in order to determine whether differences are merely a matter of chance, or whether, in accordance with the view recently expressed by Montgomery, characteristic size-relations are a constant attribute of the chromosomes individually considered.
