When double is not twice as much

Frontiers in Plant Science, 2011
Gene and genome duplications provide a playground for various selective pressures and contribute significantly to genome complexity. It is assumed that the genomes of all major eukaryotic lineages possess duplicated regions that result from gene and ...

Correlation between histological grading and ploidy status in oral leukoplakia, oral submucous fibrosis, and oral squamous cell carcinoma: A flow cytometric analysis

Journal of Pharmacy and Bioallied Sciences, 2020
Background: Methods to analyze progression of carcinogenesis and stage of cancer are vital nowadays due to the high prevalence of these lesions. DNA ploidy analysis is one such important method in early diagnosis and improving prognosis.

Induction of tetraploidy in Juncus effusus by colchicine

Biologia Plantarum, 2010
Tetraploidy was induced in vitro in mat rush (Juncus effusus L.) cultivar Nonglin-4 by exposure to colchicine (0, 50, 100 and 500 mg dm-3) for 6, 12 and 24 h. Flow cytometric analysis was used to confirm the ploidy level.

Evolution of haploid-diploid life cycles when haploid and diploid fitnesses are not equal. [PDF]

Evolution; international journal of organic evolution, 2017
Many organisms spend a significant portion of their life cycle as haploids and as diploids (a haploid-diploid life cycle). However, the evolutionary processes that could maintain this sort of life cycle are unclear. Most previous models of ploidy evolution have assumed that the fitness effects of new mutations are equal in haploids and homozygous ...
