Funding to break new scientific ground
A PIONEERING SCION PROJECT MONITORING the physiological processes inside trees in realtime and another, 3D printing scaffolding for tissue culture will receive investment funding totalling $1.9 million over three years through the Ministry of Business, Innovation and Employment’s 2022 Endeavour Fund.
The ‘Implanted sensors monitoring tree health and carbon capture efficiency’ project, in partnership with the University of Cambridge, will receive $1 million over three years to design sensors to measure the nutritional status, vitality, carbon capture efficiency and microbiome fitness of growing trees.
Precision forestry uses remote sensing tools such as satellites and drones, combined with sophisticated sensors, to detect subtle variations in plant health, nutrient and water status.
Monitoring the physiological processes inside trees in real time is the only way to fully understand how trees are responding to the environment around them and to future-proof their resilience to climate change, says Scion.
To implement this in practice, Scion will develop sophisticated low-cost bioelectronic sensors which can be implanted inside trees. These types of sensors have been used in biomedical research – but rarely used inside trees for forestry. Their use in New Zealand Radiata Pine will be pioneering.
Data generated by these sensors will be transmitted from the trees via a wireless network in the forest.
Fusing data from remote sensing together with physiological sensors within trees, combined with genome and climate data, can provide the most complete insights into a growing forest anywhere in the world.
Successful too, was the proposal, ‘Plantinspired 3D-printed scaffold for tissue culture’. Awarded $900,000 over three years, Scion scientists will explore new technology that aims to improve the tissue culture technique that makes clonal forestry possible in conifers.
Commercial forestry relies on producing vast numbers of trees – often elite clones. Somatic embryogenesis is the tissue culture technique that is used to create embryos for this purpose, but it has some limitations.
Somatic embryos can have trouble maturing on a flat surface effectively when they are sitting on a dish on a laboratory bench. In nature, these embryos would mature in a complex threedimensional structure as they interact with other cells and respond to different gradients and signals of temperature, mechanical force, nutrients and plant hormones.
Replicating this environment is extremely challenging in the laboratory, yet it is the key to successful tissue culture, says Scion.
This project will adopt sophisticated 3D printing techniques using hydrogels to create a scaffold with gradients of hormones, nutrients and porosity along its length. To visualise this scaffold, imagine a large cardboard tube with round holes in the sides and complex gradients of hormones and nutrients along its length.
While the immediate application is in the forestry industry, the same technique can be applied to other plant species, mammals and to create new biomedical opportunities.
Science leaders at Scion will also contribute to six collaborative projects that received a total of $5,754,700 from the Endeavour Fund. They involve joint research with Auckland University, WSP Research NZ, Manaaki Whenua – Landcare Research, Lincoln University, Auckland University of Technology and Massey University.
“Forests will be at the heart of a low-carbon future New Zealand. At Scion, we’re proud to lead research that will unleash the power of forestry, tackle climate change and help transition New Zealand to a circular bioeconomy,” says Scion Chief Executive, Dr Julian Elder.
