Transcription Factors and Regulatory Networks

We intend to implement the ChIP-Seq technology in sugarcane, to identify TF targets and gene promoters.

The results will have multiple direct consequences on breeding programs that frequently select for CREs and TF changes in search for genotypes better adapted to the environment and with increased agronomical performance.

We also participate in the development of the GRASSIUS database to establish sugarcane, rice, maize and sorghum regulatory networks.
