Diverse functions of Polycomb group proteins during plant development

Seminars in Cell & Developmental Biology, 2003
Polycomb group (PcG) proteins play essential roles in animal and plant life cycles by controlling the expression of important developmental regulators. These structurally heterogeneous proteins form multimeric protein complexes that control higher order chromatin structure and, thereby, the expression state of their target genes.

Nitrogen deposition magnifies destabilizing effects of plant functional group loss

Science of The Total Environment, 2022
Terrestrial ecosystems are under threat by the co-occurring biodiversity loss and nitrogen (N) deposition. Awareness is growing that the stabilizing effects of plant diversity on productivity depend on environmental context, but it remains unknown about how the loss of plant functional groups and N deposition interactively influence species richness ...

Plant functional classifications: from general groups to specific groups based on response to disturbance

Trends in Ecology & Evolution, 1997
Predicting the effects of anthropogenic changes in climate, atmospheric composition and land use on vegetation patterns has been a central concern of recent ecological research. This aim has revived the search for classification schemes that can be to group plant species according to their response to specified environmental factors. One way forward is

On a group utility function for siting a nuclear power plant

Civil Engineering Systems, 1983
Abstract A method of group decision making for selecting the optimum location for a nuclear power plant is considered. A concept of convex dependence among three decision makers, an electric power company, the users of electricity, and the population of the region is described using a hypothetical problem.

Phenotypical Variability of Functional Groups of Plants in an Urban Rainforest

Journal of Experimental Agriculture International, 2019
The functional characteristics of plants can be used to understand the changes of vegetation under different environmental pressures, since during the process of succession, the species deal with variations of luminosity, an important resource for the regeneration and growth of plants in humid tropical forests.

The Plant Ionome as a Functional Trait: Variation across Bioclimatic Regions and Functional Groups

Physiologia Plantarum
Abstract Plant chemical composition is a trait gaining increasing importance in plant ecology. However, there is limited research on the patterns and drivers of its variation among different plant functional groups and bioclimatic regions.

Ecosystem properties determined by plant functional group identity

Journal of Ecology, 2010
Summary 1. Ecosystem properties may be determined by the number of different species or groups of species in a community, the identity of those groups, and their relative abundance. The mass ratio theory predicts that the effect of species or groups of species on ecosystem properties will be dependent on their proportional abundance in a community.

Modelling plant species richness using functional groups

Ecological Modelling, 2009
Conservation biologists increasingly rely on spatial predictive models of biodiversity to support decision-making. Therefore, highly accurate and ecologically meaningful models are required at relatively broad spatial scales. While statistical techniques have been optimized to improve model accuracy, less focus has been given to the question: How does ...

Nutrient resorption patterns of plant functional groups in a tropical savanna: variation and functional significance

Oecologia, 2008
Green and senesced leaf nitrogen (N) and phosphorus (P) concentrations of different plant functional groups in savanna communities of Kruger National Park, South Africa were analyzed to determine if nutrient resorption was regulated by plant nutritional status and foliar N:P ratios. The N and P concentrations in green leaves and the N concentrations in
