Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids

FEBS Open Bio, EarlyView.
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Directed evolution of enzymes at the crossroads of tradition and innovation

FEBS Open Bio, EarlyView.
An iterative cycle of data‐driven enzyme optimization comprising four stages: genetic diversification of a template enzyme, expression of protein variants, high‐throughput evaluation, and machine‐learning‐guided redesign of the next variant library.

Guiding AlphaFold to predict how Munc13‐1 opens Syntaxin‐1

FEBS Open Bio, EarlyView.
The syntaxin‐1 Habc‐domain (orange), linker (pink) and SNARE motif (yellow) form a closed conformation that binds to Munc18‐1 (violet) and is opened by the Munc13‐1 MUN domain (cyan) to form the SNARE complex that triggers neurotransmitter release.

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.

Plant Population Density and Competition

Crops respond to plant population density modifying the characteristics of individual plants by changing the number and size of their organs. The yield response to density can be described mathematically by the “Law of Reciprocal Yield.” Mortality of ...

Density-dependent habitat selection in plants

Evolutionary Ecology, 1997
Pea plants exhibit density-dependent habitat selection as they grow. We split the root of a young pea (Pisum sativum L.) so that half grew in one pot and half in an adjacent pot. The rest of the plant remained intact. This is a ‘fence-sitter plant’. Each root-half was exposed either to no competition in its pot or to competitor plants sharing its pot ...

PLANT-TO-PLANT VARIABILITY OF MAIZE PLANTS GROWN AT DIFFERENT DENSITIES

Canadian Journal of Plant Science, 1983
Development of plant-to-plant variability in plant height, flowering characteristics and grain yield was studied in two maize (Zea mays L.) hybrids grown over 2 yr at 62 000, 93 000 and 124 000 plants/ha. The purpose of the research was to provide fundamental data on patterns of interplant variability in maize, as a foundation for more applied studies

THE DEVELOPMENT OF PLANT-TO-PLANT VARIABILITY IN MAIZE AT DIFFERENT PLANTING DENSITIES

Canadian Journal of Plant Science, 1979
The development of plant-to-plant variability in dry weight components, leaf area, plant height and ear characteristics was studied by sequential sampling in a single-cross maize (Zea mays L.) hybrid grown in the field at 50 000, 100 000, 150 000, and 200 000 plants/ha.

Plant Density and Competition

2016
Crops respond to planting density modifying the characteristics of individual plants by changing the number and size of their organs. The density response can be described mathematically by the “Law of Reciprocal Yield”. Under very high density mortality of individuals occurs and is often more pronounced when environmental conditions are more suitable (

Density Determination in Plant Communities

Oikos, 1958
In an earlier paper by the former of the present authors (BOCHER, 1935), a modification of Raunkier's method of frequency determination was described. This modification made it possible to evaluate the density of shoots or individuals in plant communities.
