Abstract:
Invasive plants are a major threat to natural ecosystems worldwide. They can outcompete native plants for resources, such as water and sunlight, and can also alter the soil chemistry and hydrology of an area. This can have a devastating impact on native plant communities and the animals that depend on them.
One of the key factors that allows invasive plants to succeed is their ability to adapt to new environments. This is often due to changes in gene expression, which can lead to changes in plant traits, such as growth rate, leaf size, and root structure.
In order to understand how invasive plants adapt to new environments, we need to have a detailed understanding of their transcriptome. The transcriptome is the collection of all RNA molecules that are produced by a cell. By studying the transcriptome, we can identify the genes that are being expressed and how their expression changes in response to different environmental conditions.
In this study, we assembled the transcriptome of a noxious weed, _Centaurea maculosa_. _C. maculosa_ is a native of Europe and Asia that has become invasive in North America. It is a major threat to native plant communities in the western United States, where it can form dense stands that exclude other plants.
We used a combination of RNA-seq and de novo assembly to generate a high-quality transcriptome assembly for _C. maculosa_. The assembly contains over 100,000 transcripts, which represent the vast majority of the genes that are expressed by the plant.
We also performed a differential gene expression analysis to identify the genes that are differentially expressed between _C. maculosa_ plants that were grown in different environments. We found that a number of genes were differentially expressed between plants that were grown in a common garden and plants that were grown in a field setting. These genes are likely to be involved in the plant's response to different environmental conditions.
The transcriptome assembly and differential gene expression analysis that we have generated in this study provide valuable new resources for studying how _C. maculosa_ and other invasive plants adapt to new environments. These resources will help us to understand the mechanisms that allow invasive plants to succeed and develop new strategies for controlling their spread.
