Effects of highland environments on clonal diversity in aquatic plants: An interspecific comparison study on the Qinghai-Tibetan Plateau

Frontiers in Plant Science, 2022
Clonal reproduction is one of the most distinctive characteristics of plants and is common and diverse in aquatic macrophytes. The balance between sexual and asexual reproduction is affected by various conditions, especially adverse environments. However,

Structure of O-Antigen and Hybrid Biosynthetic Locus in Burkholderia cenocepacia Clonal Variants Recovered from a Cystic Fibrosis Patient

Frontiers in Microbiology, 2017
Burkholderia cenocepacia is an opportunistic pathogen associated with chronic lung infections and increased risk of death in patients with cystic fibrosis (CF).

Multiple Stressor Differential Tolerances: Possible Implications at the Population Level. [PDF]

PLoS ONE, 2016
The probability of the most sensitive genotypes being eliminated from a population due to a contaminant pulse--genetic erosion--is negatively associated to the within-genotype variation.

CLONAL VARIATION IN PARAMECIUM. I. PERSISTENT UNSTABLE CLONES [PDF]

Genetics, 1972
ABSTRACT Clones of Paramecium of identical serotype when cultured in test tubes may differ in their ability to give rise to subclones of this serotype. Characteristically, stable clones yield progeny indistinguishable from their parents, while from unstable clones diverse subclones with new serotypes can be isolated repeatedly.

1H-NMR-based endometabolome profiles of Burkholderia cenocepacia clonal variants retrieved from a cystic fibrosis patient during chronic infection

Frontiers in Microbiology, 2016
During cystic fibrosis (CF) chronic lung infections, bacteria of the Burkholderia cepacia complex (Bcc) are exposed for several years to a stressful and changing environment.

Clonal reproduction and natural variation of Populus canescens patches [PDF]

Tree Physiology, 2010
Trees growing in their natural habitat represent a valuable resource for elucidating mechanisms of adaptation to environmental constraints. Along the Erqis river, there are various Populus forests, which provide 'natural laboratories' for studying tree ecophysiological responses to their habitat.

Clonal expansion within pneumococcal serotype 6C after use of seven-valent vaccine [PDF]

, 2013
Streptococcus pneumoniae causes invasive infections, primarily at the extremes of life. A seven-valent conjugate vaccine (PCV7) is used to protect against invasive pneumococcal disease in children.

Epigenetic variation in clonal stands of aspen

Folia Geobotanica, 2017
Epigenetic mechanisms can affect ecologically important traits, even in the absence of genetic variation. Environmental factors can influence gene regulation through chemical modifications, such as DNA methylation, resulting in acclimation that can be transferred to subsequent cell generations both mitotically and meiotically.

Clonal variation in the sensitivity of B16 melanoma to m-AMSA [PDF]

British Journal of Cancer, 1982
A hypothesis that m-AMSA may have greater cytotoxicity in melanin-containing tumour tissues, because it may reversibly bind to melanin, leading to prolonged drug exposure, was examined. Clonal lines of B16 melanoma which differed widely in pigmentation level were selected by isolating artificial lung colonies and in vitro soft-agar colonies, and ...
