Crop root types - responses to the environment

Understanding supply and support trade-offs in maize aerial roots
People: Amanda Rasmussen and Erin Sparks (University of Delaware) To optimise plant resilience and productivity under ever changing environments we need to understand the trade-offs between optimising different plant functions. This research explores whether there are trade-offs in support and supply for maize root types. This exciting cross-disciplinary project combines my expertise on resource supply with Sparks' expertise on mechanical support to determine whether we can identify germplasm that optimises both strength and resource capture and movement. We will unravel what controls the trade-off between supply and support to understand the boundaries so we can optimise maize varieties for local conditions, providing farmers with the best chance at future-proofing their farm and our food supplies.

- nutrient uptake and responses People: Amanda Rasmussen, Findimila Ishaya This research will improve our understanding of the functioning of an important class of roots in our most important cereal crops. Understanding how these roots respond to different environments will allow us to breed more effective crops to improve food production more sustainably.

Tree Cutting propagation
People: Amanda Rasmussen, Johnatan Vilasboa (Post doc), Nadeesha Lewke Bandara (KTP Associate), Vaishali Panwar (PhD) The UK Government has pledged to plant more trees (40,000 ha per year by 2030). This research aims to improve our understanding of different plant hormone signals controlling stem-formed roots on the base of cuttings. Improving rooting of tree cuttings from a genetically diverse base of stock-plants will facilitate the production of large scale tree plantings, multiplication of disease resistant or stress resilient trees or endangered species. Collaborators: Prof Jonathan Aylott (School of Pharmacy, UoN); Matevz Papp-Rupar, Louisa Robinson-Boyer (NIAB-EMR); Jo Clark (Future Trees Trust); Ed Marley, Kevin Hobbs (Whetman Plants International (WPI)).

Aerial roots - Ecological options for urban spaces
|
Physiological roles of aerial roots in urban environments
People: Amanda Rasmussen, Susan Abernathy Aerial roots are essential to plants growing in diverse ecological niches. They help plants climb from ground up trunks, survive in the canopy as epiphytes or stretch their roots down to the ground as hemi-epiphytes. Little is known about the physiology of these fascinating and diverse root types despite many plants selected for urban greenspace also depending on them. Understanding the physiology of stem-root types will improve urban greenspace management, enhancing plant diversity in city-scapes with flow-on implications for wider biodiversity and improving mental health.

Plants on the Pill: Crop root responses to wastewater pharmaceuticals
People: Amanda Rasmussen, MD Khaled Mosharaf (PhD student)
This research will improve our understanding of crop physiology responses to human pharmaceuticals found in waste water. Understanding how pharmaceutical interact with plant functioning during soil exposure will allow us to breed crops more efficiently with respect to water use, improving sustainable food production.
