Abstract
Dr. Ribeiro's groups has recently shown that sugarcane plants previously exposed to drought and rehydration events exhibited a better photosynthetic performance and growth rate when exposed to a new drought event compared to plants previously grown in well-watered conditions. Plant memory refers to the capacity of a previous exposure to stressful events trigger changes that regulate all plant development, allowing a more efficient and rapid response in cases of recurrent stresses. In that way, this present project aims to identify metabolic and molecular markers associated sugarcane drought memory and to evaluate its inheritance and persistence in vegetatively propagated plants. For this purpose, we intend to combine the expertise of two recognized groups in complementary areas of this project: Dr. Ribeiro's group in Brazil has been working with several important crops, focusing on their physiological responses to a myriad of abiotic stresses; complementarily, Dr Fernie group in Germany is widely known for their expertise in several well established platforms for studying plant metabolic and transcriptomic interactions. Therefore, this project will perform untargeted large-scale metabolome and transcriptome analyses on different tissues samples from sugarcane plants exposed to cycles of drought and rehydration. We will also analyze the physiological and molecular responses of these plants, associating them with memory to drought and their inheritance in propagules. Based on the obtained data, we aim to propose new management practices of pre-sprouted sugarcane seedlings in nursery condition, in addition to establishing a platform for transcriptomic analysis in this species, which will serve as a basis for the identification and understanding of the molecular mechanisms that allow memory inheritance to environmental stresses in sugarcane.
