Background:

• Transgenic herbicide-resistant (HR) turfgrass offers efficient weed control, improving lawn uniformity and aesthetics.
• Genetically modified organisms (GMOs) like HR turfgrass raise public concerns regarding biosafety and legal aspects.
• Metabolomics provides a comprehensive analysis of biological systems, aiding in the characterization of transgenic grass metabolism.

Purpose of the Study:

• To review metabolomics applications for predicting molecular and physiological phenotypes of HR turfgrass.
• To identify metabolic alterations in genetically modified turfgrass conferring herbicide resistance.
• To provide background on metabolomics, HR crop transformation, biosafety, and turfgrass value.

Main Methods:

• Reviewing recent applications of metabolomics in HR crops.
• Analyzing metabolomics data to predict phenotypes of glyphosate-resistant Kentucky bluegrass and glufosinate-resistant creeping bentgrass.
• Compiling information on turfgrass botany, economic, and aesthetic value.

Main Results:

• Metabolomics can identify specific metabolic alterations in HR turfgrass due to genetic modification.
• This approach aids in understanding the biosafety profile of transgenic turfgrass.
• Metabolomics data can inform public perception and regulatory assessments.

Conclusions:

• Metabolomics is a valuable tool for characterizing HR turfgrass metabolism and assessing biosafety.
• Understanding metabolic phenotypes is crucial for addressing public concerns about GMO turfgrass.
• This review highlights the potential of metabolomics in the development and regulation of HR turfgrass.
