Postdoctoral research fellow
Dr Melino is passionate about improving plant nutrition. She is interested in understanding how plant roots take up nitrogen and recycle internal sources of nitrogen. Dr Melino is looking for high performing wheat cultivars that acquire soil nitrogen fertiliser in early stages of growth. This includes looking closely at how root architecture and nitrate transport changes with nitrogen supply. She is also identifying whether high performing wheat cultivars use an internal source of nitrogen-rich metabolites to support growth under stress conditions.
Her previous research at the Centre for Rhizobium Studies at Murdoch University was on the symbiotic interaction between clover and rhizobia. She characterised the incompatibility for nitrogen fixation that exists between clover hosts and strains of distinct geographic origins and predicted the genetic cause using a whole bacterial genome sequencing approach.
