Adaptive laboratory evolution enhances cell yield and lipid production of Chlorella sorokiniana under mildly cold conditions

Frontiers in Microbiology
One challenge to large-scale microalgae cultivation, e.g., for biodiesel production, is the seasonal low-temperature conditions. We argue that seasonally varying selection in natural environments has prevented algae from better adapting to cold ...

GENETIC CHANGES WITH GENERATIONS OF ARTIFICIAL SELECTION [PDF]

Genetics, 1980
ABSTRACT Using conditional probabilities and moment-generating matrices, I derived approximate algebraic equations that give expectations of gene frequency, population mean, gene frequency variance within lines, or heterozygosity, and gene frequency variance between lines, or drift, for repeated cycles of recurrent selection in ...

Single‐cell DNA methylation profiling: Technologies, computation, and applications in precision oncology

Molecular Oncology, EarlyView.
Single‐cell DNA methylation (scDNAme) profiling maps epimutational clonal evolution, revealing mechanisms of malignancy and therapeutic resistance across diverse cancer types. By providing a high‐resolution landscape of intratumoral heterogeneity, these technologies empower precise patient stratification, guide the development of enhanced ...

Intraspecific variation in morphological and defensive traits of guava genotypes and their implications for herbivory

Frontiers in Horticulture
IntroductionIntraspecific genotypic variation arising from artificial selection can shift how plants allocate resources, often unbalancing traits related to growth, reproduction, and defense.

Artificial selection for food colour preferences [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2015
Colour is an important factor in food detection and acquisition by animals using visually based foraging. Colour can be used to identify the suitability of a food source or improve the efficiency of food detection, and can even be linked to mate choice. Food colour preferences are known to exist, but whether these preferences are heritable

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.

The Phenotypic and the Genetic Response to the Extreme High Temperature Provides New Insight Into Thermal Tolerance for the Pacific Oyster Crassostrea gigas

Frontiers in Marine Science, 2020
Investigating responses of organisms to stressful or new environments with selection pressure is one of the crucial problems in evolutionary biology, and it is of importance to understand the phenotypic and molecular mechanism underlying thermal ...
