Genome size and DNA base composition of geophytes: the mirror of phenology and ecology?
Although geophytism together with producing larger cells appears to be an advantageous strategy for fast development of an organism in seasonal habitats, the drought sensitivity of large stomata may restrict the occurrence of geophytes with very large genomes to regions not subject to water stress.

Significance Our large-scale survey of genomic nucleotide composition across monocots has enabled the first rigorous testing, to our knowledge, of its biological significance in plants. We show that…
Ancestral Chromosomal Blocks Are Triplicated in Brassiceae Species with Varying Chromosome Number and Genome Size1
These findings provide compelling evidence of an ancient hexaploidization event and corresponding whole-genome triplication shared by the tribe Brassiceae, demonstrating the usefulness of comparative cytogenetics for elucidation of phylogenetic relationships.
Understanding intraspecific variation in genome size in plants
The recent progress in understanding the spatio-temporal dynamics of intraspecific variation in genome size caused by the gradual accumulation of mutations is reviewed.
Genome size variation in Central European species of Cirsium (Compositae) and their natural hybrids.
Considerable differences in nuclear DNA content exist among Central European species of Cirsium on the diploid level and a negative relationship was detected between the genome size and the tendency to form natural interspecific hybrids.
Evolution of genome size in Carex (Cyperaceae) in relation to chromosome number and genomic base composition.
It is concluded that the evolution of genome and karyotype in Carex is promoted by frequent chromosomal fissions/fusions, rare polyploidy and common repetitive DNA proliferation/removal.
Genome size and GC content evolution of Festuca: ancestral expansion and subsequent reduction.
The present study indicates the high potential of general quantitative characters of the genome for understanding the long-term processes of genome evolution, testing evolutionary hypotheses and their usefulness for large-scale genomic projects.

The absence of correlation between genomic parameters and ecological variables suggests that the driving forces of miniaturization are of intrinsic nature, and the extreme dynamics of Lentibulariaceae genomes provides a unique opportunity for studying genomeminiaturization and GC content variation.
