Sugarcane Protein Kinases

Protein Kinases activate signaling cascades in response to environmental stimuli and our studies point to a predominant role of PKs in the regulation of sucrose content and drought responses.

To identify new genes associated to brix, drought and lignin content we are characterizing the transcriptome of genotypes and cultivars that contrast for these traits using olinonucleotide arrays. Genes of interest will be functionally evaluated by generating transgenics altered for their expression. A catalogue of Sugarcane Signal Transduction components has been produced.
