Plasticity of flower longevity in alpine plants is increased in populations from high elevation compared to low elevation populations

open access: yesAlpine Botany, 2016
Flower longevity is an adaptive trait, optimized to balance reproductive success against the costs of flower maintenance. The trait is highly plastic in response to pollination success, and numerous studies report increased flower longevity in high ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Physiological and biochemical changes during flower senescence of herbaceous peony and a new postharvest approach for extending flower longevity

open access: yesOrnamental Plant Research
The herbaceous peony is a significant cut-flower plant cultivated worldwide. However, the in-depth understanding of herbaceous peony flower senescence is scarce, and the short natural florescence substantially restricts its industrial development.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

open access: yesAging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications

open access: yesAdvanced Materials, EarlyView.
Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

Evaluation of Ornamental and Postharvest Potential of Oil-Type Sunflower Genotypes Grown Under Dense Sowing Conditions

open access: yesHorticulturae
Sunflower is predominantly cultivated and extensively studied as an oil-type crop, which has contributed to the development of broad genetic variability within oil-type germplasm.

Genotypic Variation in Postharvest Flower Longevity of Asiatic Hybrid Lilies [PDF]

open access: yesJournal of the American Society for Horticultural Science, 1998
Genotypic variation in postharvest flower longevity was determined for 63 Asiatic lily hybrids ( Lilium L.). The reliability of standardized test conditions for longevity screening was also examined. Improvement of lily flower longevity by breeding appears feasible.
