A Model of Genome Size Evolution for Prokaryotes in Stable and Fluctuating Environments [PDF]

, 2015
Temporal variability in ecosystems significantly impacts species diversity and ecosystem productivity and therefore the evolution of organisms. Different levels of environmental perturbations such as seasonal fluctuations, natural disasters, and global ...

Divide to Conquer: Evolutionary History of Allioideae Tribes (Amaryllidaceae) Is Linked to Distinct Trends of Karyotype Evolution

Frontiers in Plant Science, 2020
Allioideae (e.g., chives, garlics, onions) comprises three mainly temperate tribes: Allieae (800 species from the northern hemisphere), Gilliesieae (80 South American species), and Tulbaghieae (26 Southern African species). We reconstructed the phylogeny

The Evolutionary Patterns of Genome Size in Ensifera (Insecta: Orthoptera)

Frontiers in Genetics, 2021
Genomic size variation has long been a focus for biologists. However, due to the lack of genome size data, the mechanisms behind this variation and the biological significance of insect genome size are rarely studied systematically. The detailed taxonomy

Genome size and genomicGCcontent evolution in the miniature genome‐sized family Lentibulariaceae [PDF]

New Phytologist, 2014
• Lentibulariaceae contains species with the smallest genome size in tracheophytes, yet data are available only for 8% of its species. This prevents understanding of the history of miniaturization events and their possible reasons. Nothing is known about the variation of genomic DNA base composition.

Methods of internal standards’ preservation for genome size assessments: a comparative study

Caryologia
Assessing genome size in plant species using flow cytometry requires fresh plant material from both the target species and appropriate internal standards. The use of fresh material from the standards is sometimes difficult.

A dormant resource for genome size estimation in ferns: C‐value inference of the Ophioglossaceae using herbarium specimen spores

Applications in Plant Sciences, 2021
Premise The great variation of genome size (C‐value) across land plants is linked to various adaptative features. Flow cytometry (FCM), the standard approach to estimating C‐values, relies mostly on fresh materials, performing poorly when used with ...

Treatment Decision‐Making Roles and Preferences Among Adolescents and Young Adults With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Decision‐making (DM) dynamics between adolescents and young adults (AYAs) with cancer, parents, and oncologists remain underexplored in diverse populations. We examined cancer treatment DM preferences among an ethnically and socioeconomically diverse group of AYAs and their parents.

Intragenomic Conflict between Knob Heterochromatin and B Chromosomes Is the Key to Understand Genome Size Variation along Altitudinal Clines in Maize

Plants, 2021
In maize, we studied the causes of genome size variation and their correlates with cultivation altitude that suggests the existence of adaptive clines.

Novel Genetic Risk Factor Identified for L‐Asparaginase‐Induced Pancreatitis in Pediatric Patients With Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background L‐asparaginase is a critical component in treatment protocols for pediatric acute lymphoblastic leukemia. Acute pancreatitis reactions can necessitate delays and, in some cases, discontinuation of L‐asparaginase, which compromises outcomes.
