Summary
Researchers are developing new methods to study gene function in whole organisms using transformed plants in their natural environments. This approach aims to enhance our understanding of how genes influence an organism's survival and evolution.
Area of Science:
- Molecular Ecology
- Evolutionary Biology
- Plant Sciences
Background:
- Understanding gene function at the organism level is crucial for evolutionary biology.
- Existing gene expression systems often limit the study of whole-organism gene function.
- Natural selection acts on traits influenced by genes, affecting their persistence or modification.
Purpose of the Study:
- To develop novel experimental systems for measuring whole-organism gene function.
- To train "molecularly enabled field biologists" capable of studying gene expression in natural settings.
- To investigate the role of environmentally regulated genes in organismal fitness.
Main Methods:
- Utilizing transformed plants with silenced, environmentally regulated genes.
- Employing natural habitats as experimental "laboratories" for gene function studies.
- Analyzing the impact of gene silencing on organismal fitness and evolutionary trajectories.
Main Results:
- Demonstrated the feasibility of studying gene function in natural ecosystems.
- Provided examples using threonine deaminase and RNA-directed RNA polymerases to illustrate the methodology.
- Highlighted the potential for increased understanding of gene-organism interactions.
Conclusions:
- This approach offers a powerful new avenue for connecting molecular genetics with ecological and evolutionary processes.
- Studying gene function in native habitats can reveal insights into Darwinian fitness.
- The training of "molecularly enabled field biologists" is key to advancing this research area.

01:59Plant Breeding and Biotechnology
Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.
02:02Genomics
Genomics is the science of genomes: it is the study of all the genetic material of an organism. In humans, the genome consists of information carried in 23 pairs of chromosomes in the nucleus, as well as mitochondrial DNA. In genomics, both coding and non-coding DNA is sequenced and analyzed. Genomics allows a better understanding of all living things, their evolution, and their diversity. It has a myriad of uses: for example, to build phylogenetic trees, to improve productivity and...
01:16In-vitro Mutagenesis
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.
02:11Reporter Genes
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
