Abstract

The aim of this project is to establish a transformation protocol for Brachypodium distachyon in order to use it as an alternative model for sugarcane. Research on biological models is important because they provide useful information about organisms whose research is challenging and difficulties for lab research. In order to transform Brachypodium, immature embryos will be used to obtain embriogenic calli with potential to regenerate into new plants. The embryonic calli will be transformed with Agrobacterium tumefaciens (GV3101), which will integrate LUC (LUCIFERASE) under the control of the promoters of BdCCA1 (CIRCADIAN CLOCK ASSOCIATED1) and BdTOC1 (TIME OF CHLORORPHYLL A/B BINDING PROTEIN EXPRESSION), genes that control the circadian clock. The circadian clock modulates most of the biological processes in plants. LUC will allow us to monitor to the circadian clock activity in Brachypodium distachyon in a minimally invasive way. The development of transformation techniques in Brachypodium distachyon and a better understanding of its circadian clock will increase the array of tools available to study sugarcane.
