Expression data from Arabidopsis suspension cells overexpressing LHW and T5L1-GFP. Arabidopsis thaliana

Plant vascular tissues are essential for the existence of land plants. Many studies have revealed the process underlying the development of vascular tissues. However, the initiation of vascular development is still a mystery. LONESOME HIGHWAY (LHW), which encodes a bHLH transcription factor, is expressed in the initial step of vascular development in roots. LHW and TMO5 LIKE1 (T5L1) interact each other and function as a heterodimer. Here, we identified specific genes downstream of LHW-T5L1 with transformed suspension culture cells in microarray experiments. Overall design: To identify genes downstream of LHW-T5L1, we collected three samples at 0h and 12h with or without estrogen with triplicates.
