Mature Citrus Facility

Mature Citrus Facility

The University of Florida, Institute of Food and Agricultural Science (UF/IFAS) and the Citrus Research and Development Foundation (CRDF) established The Mature Citrus Facility (MCF) at the Citrus Research and Education Center (CREC) in Lake Alfred, FL in 2011. This is a fee-for-service production facility for scientists, growers, and industry. Targets include tolerance or resistance to citrus greening or Huanglongbing (HLB), canker and other value-added traits. Mature citrus will flower and fruit earlier than immature citrus, enabling examination of these traits in genetically altered plants.

Mission and goal: Our mission is to accelerate solutions for pests and diseases threatening the Florida citrus industry. Our goal is to produce mature transgenic, cis/intragenic or edited citrus, containing desirable traits for research, testing, and potential commercialization.

ProceduresWe routinely use Dr. Leandro Pena’s Agrobacterium protocol for transformations, but we can also produce cis/intragenics using our own protocol for biolistics, free of plant pest sequences. We are also developing protocols for gene editing of mature citrus using biolistics. A variety of mature sweet orange scions can be transformed that enable early flowering and fruiting. Shoot-tip-grafting can be performed to clean plant material, or plants can be vegetatively propagated (budded or rooted) into replicates. Our priority is to produce mature scions resistant to HLB.
