HLB Tolerance Data Expected in Early 2023
Conclusive data on trials in the Millennium Block, expected in early 2023, may reveal which of more than 5,500 trees can tolerate HLB, researchers say. The Millennium Block is at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) Indian River Research and Education Center (IRREC) in Fort Pierce. IRREC Director Ronald Cave said the 20-acre grove, established …
Canker Resistance Progress May Help With HLB
A team of researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) has successfully identified the CsDMR6 gene, which impacts a citrus tree’s reaction to the citrus canker pathogen. Zhanao Deng and Fred Gmitter, both professors and plant breeders, are members of that team. By editing the CsDMR6 gene in the plant’s DNA to interfere with …
