Research Project: The Development of Novel Blood and Cara Cara Like Citrus Varieties

Location: Crop Improvement and Genetics Research

Project Number: 2030-21000-020-06
Project Type: Trust

Start Date: Oct 01, 2012
End Date: Sep 30, 2015

Objective:
The goal of the project is to develop the molecular tools enabling the production of citrus plants that accumulate lycopene and/or anthocyanin nutrients within their fruit. Improved biotechnological tools facilitating the genetic engineering of citrus species will also be developed.

Approach:
Novel transformation constructs designed to activate the metabolic pathway for lycopene production and/or anthocyanin production in citrus fruit will be built and introduced into citrus and tomato plants using Agrobacterium-mediated transformation. These constructs will also carry recombinase attachment sites allowing the testing of novel transgene targeting and excision strategies within the plant genome. Also, citrus fruit-specific promoters that will facilitate the precise expression of transgenes conferring lycopene and anthocyanin production will be identified and characterized. This research is synergistic to previous grants obtained from the CRB.
