Lessons learned and recommendations in conducting solutions-driven environmental and public health research.

Solutions-driven research is a transdisciplinary approach that incorporates diverse forms of expertise to identify solutions to stakeholder-identified environmental problems. This qualitative evaluation of early solutions-driven research projects provides transferable recommendations to improve researcher and stakeholder experiences and outcomes in transdisciplinary environmental research projects.

DeepLearnMOR: a deep-learning framework for fluorescence image-based classification of organelle morphology.

The proper biogenesis, morphogenesis, and dynamics of subcellular organelles are essential to their metabolic functions. Conventional techniques for identifying, classifying, and quantifying abnormalities in organelle morphology are largely manual and time-consuming, and require specific expertise. Deep learning has the potential to revolutionize image-based screens by greatly improving their scope, speed, and efficiency.

The synthesis of xyloglucan, an abundant plant cell wall polysaccharide, requires CSLC function.

Xyloglucan (XyG) is an abundant component of the primary cell walls of most plants. While the structure of XyG has been well studied, much remains to be learned about its biosynthesis. Here we employed reverse genetics to investigate the role of cellulose synthase like-C (CSLC) proteins in XyG biosynthesis.

What Goes Up Must Come Down: Integrating Air and Water Quality Monitoring for Nutrients.

Excess nitrogen and phosphorus ("nutrients") loadings continue to affect ecosystem function and human health across the U.S. Our ability to connect atmospheric inputs of nutrients to aquatic end points remains limited due to uncoupled air and water quality monitoring.

Ecosystem services in the Great Lakes.

A comprehensive inventory of ecosystem services across the entire Great Lakes basin is currently lacking and is needed to make informed management decisions. A greater appreciation and understanding of ecosystem services, including both use and non-use services, may have avoided misguided resource management decisions in the past that have resulted in legacies inherited by future generations. Given the interest in ecosystem services and lack of a coherent approach to addressing this topic in the Great Lakes, a summit was convened involving 28 experts working on various aspects of ecosystem services in the Great Lakes.

Ecosystem services in risk assessment and management.

The ecosystem services (ES) concept holds much promise for environmental decision making. Even so, the concept has yet to gain full traction in the decisions and policies of environmental agencies in the United States, Europe, and elsewhere. In this paper we examine the opportunities for and implications of including ES in risk assessments and the risk management decisions that they inform.

Ecosystem services as assessment endpoints for ecological risk assessment.

Ecosystem services are defined as the outputs of ecological processes that contribute to human welfare or have the potential to do so in the future. Those outputs include food and drinking water, clean air and water, and pollinated crops. The need to protect the services provided by natural systems has been recognized previously, but ecosystem services have not been formally incorporated into ecological risk assessment practice in a general way in the United States.

In vivo imaging of the S-locus receptor kinase, the female specificity determinant of self-incompatibility, in transgenic self-incompatible Arabidopsis thaliana.

Background And Aims: The S-locus receptor kinase (SRK), which is expressed in stigma epidermal cells, is responsible for the recognition and inhibition of 'self' pollen in the self-incompatibility (SI) response of the Brassicaceae. The allele-specific interaction of SRK with its cognate pollen coat-localized ligand, the S-locus cysteine-rich (SCR) protein, is thought to trigger a signalling cascade within the stigma epidermal cell that leads to the arrest of 'self' pollen at the stigma surface. In addition to the full-length signalling SRK receptor, stigma epidermal cells express two other SRK protein species that lack the kinase domain and whose role in the SI response is not understood: a soluble version of the SRK ectodomain designated eSRK and a membrane-tethered form designated tSRK.

Toward a standard lexicon for ecosystem services.

The complex, widely dispersed, and cumulative environmental challenges currently facing society require holistic, transdisciplinary approaches to resolve. The concept of ecosystem services (ES) has become more widely accepted as a framework that fosters a broader systems perspective of sustainability and can make science more responsive to the needs of decision makers and the public. Successful transdisciplinary approaches require a common language and understanding of key concepts.

Exploring the role of a stigma-expressed plant U-box gene in the pollination responses of transgenic self-incompatible Arabidopsis thaliana.

Recognition of "self" pollen in the self-incompatibility (SI) response of the Brassicaceae is determined by allele-specific interaction between the S-locus receptor kinase (SRK), a transmembrane protein of the stigma epidermis, and its ligand, the pollen coat-localized S-locus cysteine-rich (SCR) protein. The current model for SRK-mediated signaling proposes a central role for the plant U-box (PUB) Armadillo repeat-containing protein ARC1, an E3 ligase that interacts with, and is phosphorylated by, the kinase domain of SRK. According to the model, activated ARC1 causes the degradation of factors required for successful pollen tube growth.

The role of the atmosphere in the provision of ecosystem services.

Solving the environmental problems that we are facing today requires holistic approaches to analysis and decision making that include social and economic aspects. The concept of ecosystem services, defined as the benefits people obtain from ecosystems, is one potential tool to perform such assessments. The objective of this paper is to demonstrate the need for an integrated approach that explicitly includes the contribution of atmospheric processes and functions to the quantification of air-ecosystem services.
