Litchi Aroma Terpenoid Profiles and Gene Expression Data

24 litchi cultivars were profiled to identify 14 key terpenoids, such as caryophyllene and geraniol, which classify cultivars into aroma groups. The dataset includes results from genome-wide screening of 46 LcTPS genes and functional assays linking transcription factor LcCDF3 to LcTPS39 expression. It supports research on the genetic regulation of floral-fruity aroma in litchi aril.

Use Cases

• Analyze the correlation between 14 key terpenoid concentrations and the classification of 24 litchi cultivars into light or strong aroma groups.
• Investigate the expression patterns of 46 LcTPS genes, particularly LcTPS39, across different litchi cultivars to identify aroma-related biosynthetic genes.
• Model the regulatory relationship between transcription factor LcCDF3 and the LcTPS39 promoter using in vitro and in vivo assay data.
• Compare caryophyllene production levels in litchi callus and tomato fruit samples following LcCDF3 overexpression experiments.

Strengths

• Profiles 24 distinct litchi cultivars, providing a comparative basis for aroma studies.
• Identifies 14 specific key terpenoids, including caryophyllene and geraniol, with analytical measurements.
• Includes data from a genome-wide screening of 46 LcTPS genes and subsequent functional validation assays.

Limitations

• The dataset is small in file size (225.5 KB), indicating limited raw data volume for large-scale statistical modeling.
• Data is derived from a specific experimental study on litchi, limiting generalizability to other fruit species without further validation.
• Temporal and broader geographic coverage of the litchi samples is not specified in the input.
