Costs and Benefits of Transgenerational Induced Resistance in Arabidopsis

Frontiers in Plant Science, 2021
Recent evidence suggests that stressed plants employ epigenetic mechanisms to transmit acquired resistance traits to their progeny. However, the evolutionary and ecological significance of transgenerational induced resistance (t-IR) is poorly understood ...

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Environment-driven reprogramming of gamete DNA methylation occurs during maturation and is transmitted intergenerationally in Atlantic Salmon

G3: Genes, Genomes, Genetics, 2021
An epigenetic basis for transgenerational plasticity in animals is widely theorized, but convincing empirical support is limited by taxa-specific differences in the presence and role of epigenetic mechanisms.

How developmental stressors affect mitochondrial respiratory function: a systematic review and meta‐analysis

Biological Reviews, EarlyView.
ABSTRACT The environmental conditions organisms experience during early development can have powerful and sustained effects on morphology, physiology, behaviour, and performance. Such developmental effects can influence reproductive success, survival, and life‐history strategies and can be transmitted across generations (i.e.

Rapid within‐ and transgenerational changes in thermal tolerance and fitness in variable thermal landscapes

Ecology and Evolution, 2020
Phenotypic plasticity may increase the performance and fitness and allow organisms to cope with variable environmental conditions. We studied within‐generation plasticity and transgenerational effects of thermal conditions on temperature tolerance and ...

Transgenerational effects of stress exposure on offspring phenotypes in apomictic dandelion. [PDF]

PLoS ONE, 2012
Heritable epigenetic modulation of gene expression is a candidate mechanism to explain parental environmental effects on offspring phenotypes, but current evidence for environment-induced epigenetic changes that persist in offspring generations is scarce.

Sustainable Business Model Innovation and Firm's Performance: A Multiple Case Study in the Agri‐Food Industry

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This research investigates how sustainability‐oriented initiatives aimed at innovating a firm's business model can lead to different economic, social and environmental performance configurations, with the objective of identifying the determinants that explain these differences. We carried out a multiple case study, selecting firms based on the

Temperature-size responses during ontogeny are independent of progenitors’ thermal environments [PDF]

PeerJ
Background Warming generally induces faster developmental and growth rates, resulting in smaller asymptotic sizes of adults in warmer environments (a pattern known as the temperature-size rule).

Transgenerational effect alters the interspecific competition between two dominant species in a temperate steppe

Ecology and Evolution, 2021
One of the key aims of global change studies is to predict more accurately how plant community composition responds to future environmental changes. Although interspecific relationship is one of the most important forces structuring plant communities, it

A shining starlet: Nematostella vectensis as a model for developmental, regenerative, and comparative biology

Developmental Dynamics, EarlyView.
Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.
