Gene Expression

To understand how plants respond to various environments, Oak Ridge National Laboratory (ORNL) researchers have mapped gene expression in plants that use different photosynthesis strategies. Here, blue edges show positive correlations in gene expression between Kalanchoë genes (dark green nodes) and pineapple genes (yellow nodes). Red edges show negative correlations between gene expression in Kalanchoë and pineapple and in Arabidopsis (light green nodes), a model plant that uses a different photosynthesis strategy.
