Understanding how climate change is affecting plant growth is highly relevant given the potential to improve and increase crop production worldwide. The current collaborative SPRINT proposal will take advantage of already available Kalanchoë pinnata lines transformed with 35S::rolC and 35S::rolB (Danish partners) to investigate the impact of abiotic stresses, i.e. UV-B and drought, on growth and flavonoid accumulation in relation to untransformed plants (control).The hypothesis is that large-scale changes in gene expression are associated with rol overexpression and involve ROS-mediated signaling through MCF members.Therefore, diferente approaches will be employed to assess ROS and flavonoid accumulation as well as transcriptomic changes,and differentially expressed genes (DEG) in these plants.
