Project title: Advanced cryobanking for propagation-recalcitrant and critically endangered plant species.

Dates: 2009 - 2017

Funding: Australian Research Council (ARC) Linkage Projects schemes

Location: Biodiversity Conservation Centre (Kings Park)

Research themes

  • rare species conservation
  • south-west Western Australian species
  • cryopreservation
  • tissue culture
  • plant physiology
  • plant metabolomics

Project description

This project will advance methods for the repatriation of recalcitrant/threatened plant species to post-mined sites to achieve best practice ecological restoration in areas of high biodiversity. In particular, the nature of freezing and dehydration damage to cell membranes at various stages of tissue culture and cryopreservation will be investigated to try to minimise its deleterious effects.

In addition, metabolic changes that affect cryogenic survival will be assessed to provide further insight into the role of oxidative stress and the toxicity of cryopreservation processes. Ultimately improved cryogenic protocols will be developed to maintain the integrity of long-term cryobanks of key species for post-mining ecological restoration.
