Phytochrome B inhibits the activity of phytochrome-interacting factor 7 involving phase separation

Cell Reports, 2023
Summary: Shade-intolerant plants sense changes in the light environment and trigger shade-avoidance syndrome in the presence of neighboring vegetation. Phytochrome-interacting factor 7 (PIF7) is an essential regulator that integrates shade signals into ...

Light intensity modulates the regulatory network of the shade avoidance response in Arabidopsis. [PDF]

, 2014
Plants such as Arabidopsis thaliana respond to foliar shade and neighbors who may become competitors for light resources by elongation growth to secure access to unfiltered sunlight.

High planting density induces the expression of GA3-oxidase in leaves and GA mediated stem elongation in bioenergy sorghum

Scientific Reports, 2021
The stems of bioenergy sorghum hybrids at harvest are > 4 m long, contain > 40 internodes and account for ~ 80% of harvested biomass. In this study, bioenergy sorghum hybrids were grown at four planting densities (~ 20,000 to 132,000 plants/ha) under ...

Clouds, shadows, or twilight? Mayfly nymphs recognise the difference [PDF]

, 2006
1. We examined the relative changes in light intensity that initiate night-time locomotor activity changes in nymphs of the mayfly, Stenonema modestum (Heptageniidae).

The skills required for transition to university and study in biological sciences: A student perspective

FEBS Open Bio, EarlyView.
Bioscience students were asked for their opinions on the value and teaching of skills. 204 responded that teamwork, time management and study skills are necessary to reach University, that scientific writing, research, laboratory and presentation skills are taught effectively during their studies, while other skills are gained inherently through study ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions

Advanced Engineering Materials, EarlyView.
This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Avoiding Based on Shades of Gray: Generalization of Pain-Related Avoidance Behavior to Novel Contexts [PDF]

The Journal of Pain, 2020
Avoidance behavior is protective, yet in the absence of genuine bodily threat, it may become disabling. Therefore, we investigated whether avoidance generalizes to novel safe contexts based on the similarity with the acquisition context. Healthy participants performed arm movements using a robotic arm to reach a target. Three trajectories (T1-3) led to
