Assembling the transcriptome of a noxious weed: New resources for studying how plants invade
Date:3/5/2013

lation from its invasive range (Oregon). Comparing transcriptomes across ranges will reveal new changes in gene expression in the highly successful invasive population. "This system has great potential as a comparative framework for studying adaptation to new environments and invasion," comments Jaiswal.

To allow future studies to identify the functions of slender false brome genes, the authors also compared the false brome transcriptome to those of well-studied agricultural species, including rice and sorghum. If false brome possesses a gene that has already been studied in an agricultural species, it will be easier to identify the gene's supposed function. The teams from Jaiswal's and Cruzan's laboratories are exploring these newly developed genetic resources, which may provide insights into how slender false brome has adapted to Oregon's different environmental conditions.

The authors published their results, including details on data retrieval, in the March issue of Applications in Plant Sciences (available for free viewing at http://www.bioone.org/doi/pdf/10.3732/apps.1200011). Fox and Cruzan note, "The seed and genomic resources are publicly available, so it would be relatively easy for any research group to establish a research program focused on slender false brome."
