SEATTLE - Oct. 26, 2017 - PRLog -- SEATTLE, Wash. – October 26, 2017 – Phytelligence, an agricultural biotechnology company revolutionizing the way food crops are grown,has signed a citrus rootstock licensing agreement with Florida Foundation Seed Producers, giving Phytelligence customers the opportunity to access true-to-type, virus and disease free rootstock that's also resistant to citrus-greening disease.

The licensed rootstocks were released as part of the University of Florida's Citrus Fast Track Release Option. The citrus rootstocks were selected based on their resistance to Huanglongbing disease (HLB, or citrus greening disease) during field trials under severe HLB disease pressure. Scion trees grafted onto these rootstocks showed a reduced frequency of infection and reduced disease symptoms once infected when compared to other commercial rootstocks, according to the Florida Foundation Seed Producers.

The University of Florida license gives Phytelligence propagation rights to the following citrus rootstock cultivars:

·      UFR-1

·      UFR-2

·      UFR-3

·      UFR-4

·      UFR-5

·      UFR-6

·      UFR-15

·      UFR-16

·      UFR-17

As part of their emphasis on replenishing the citrus industry in Florida, Phytelligence will immediately establish Florida-based facilities to begin the rootstock initiation process. Phytelligence will also continue to genetically confirm all rootstocks that come from their facilities, eliminating the rootstock mix-up issues prevalent in the industry. In addition to being genetically confirmed via a DNA-based process, all plants produced by Phytelligence are disease and virus free.

"It is absolutely critical to plant trees with rootstocks that are tolerant, or even resistant, to citrus greening disease and the only way to be 100 percent sure the rootstocks planted are true-to-type, is to use a DNA-based certification process," stated Dr. Fred Gmitter, Citrus Breeder, University of Florida.

Citrus greening disease has plagued Florida and the surrounding areas, leading growers to rip out infected trees and scramble to plant new, disease-resistant rootstock. The combination of infected orchards and recent natural disasters has left growers with few options to obtain citrus-greening disease-resistant rootstock to replant. With this licensing deal, Phytelligence will be able to provide confirmed true-to-type rootstock to growers at a much more rapid pace.
